Care FAQ

Healthy, well-handled rats very rarely bite. A rat that has been socialised calmly from a young age will almost never bite their owner, and most bites that do happen are either accidental, for example mistaking a finger for food, or a response to fear or pain rather than aggression.

If a rat does nip, think about what caused it rather than treating it as a character flaw. A nervous rat that bites when cornered will usually become much gentler with patient, consistent handling over time. Biting is not a normal part of life with well-kept rats.

Yes, often surprisingly so. Many rats will actively seek out their owner, climb onto them for a rest, and groom their hands or hair. They recognise familiar people and often clearly prefer them over strangers.

Individual personalities vary, and shyer rats may take longer to come around, but most do with calm, consistent handling. Bruxing (a gentle tooth-grinding sound) and boggling (the eyes appear to vibrate slightly) are signs of contentment you will often notice during quiet moments together.

Even 10 to 15 minutes of calm handling each day makes a real difference to bonding over time. Consistency counts for more than long sessions, especially with younger or more nervous rats.

Yes. Rats are highly social animals and should always be kept with at least one companion. A rat kept alone is likely to become bored and stressed, which can affect both their behaviour and their health over time.

A minimum of two is the standard recommendation, though three or more (a mischief) is often more stable. Same-sex groups are usually straightforward to manage. The extra cost of keeping two rats rather than one is small compared to the difference it makes to their wellbeing.

Rats should always be kept in pairs or groups. They are deeply social animals and a lone rat will almost always become withdrawn or anxious over time, however attentive their owner is. The only exception is a rat who has recently lost a companion; some need a short period before being introduced to new rats, but even then, companionship should be the goal.

Always get at least two. Most people find a pair no harder to keep than one, and the difference it makes to their quality of life is significant.

Rats should always be kept separate from cats and dogs. Even a calm, friendly cat or dog has strong natural prey instincts, and a rat can be seriously injured in a moment of excitement that the larger animal did not intend as aggression.

Rats need a secure cage that other animals cannot access, and they should never be left in the same space unsupervised. The safest approach is to treat them as separate parts of the household entirely.

Yes, many owners do and it works well. Having the cage nearby makes it easier to notice changes in behaviour and means your rats get more incidental interaction throughout the day.

A few practical things to consider: rats are most active in the evening and at night, so some noise from movement and chewing is normal after dark. Some people also find they are mildly allergic to rat dander over time, which is worth being aware of if you have a history of pet allergies. Good ventilation in the room (or an air purifier) and keeping bedding clean helps with both.

Both have real advantages depending on your situation. Baby rats (kittens) are often easier to bond with and can be tamed to your specific household from the start, but they are more time-intensive early on and can be more nippy and hyperactive during adolescence.

Adult rats, particularly those from a rescue, are often already socialised and their personality is established, so you know what you are getting. They may take a little longer to bond with new owners but many settle in quickly. If you are a first-time owner with limited time for intensive socialisation, an already-handled young adult can actually be a gentler introduction to rat keeping.

Most pet rats live between two and three years, with some well-cared-for individuals reaching four years or beyond. Two years is often cited as the average, but rats from reputable breeders with good genetics and attentive care regularly exceed that. Genetics, diet and the quality of their environment all play a significant part.

Because their lives are relatively short, health changes can develop quickly. Getting into the habit of a simple weekly check at home, looking at weight, coat condition, breathing and behaviour, means you are more likely to catch anything early. Finding an exotic-savvy vet before you actually need one urgently is one of the most practical things a new rat owner can do.

Often yes, though not always. Rats from pet shops or feeder lines tend to have shorter lifespans, not because they are bred to die young, but because mass breeding rarely selects for health or longevity. Poor genetics, high stress environments, and little to no health screening all play a part.

A rat from a responsible breeder or a specialist rescue is more likely to reach the higher end of the lifespan range. If you are still choosing where to get your rats from, researching breeders who health test their lines and can tell you about the parents is time well spent.

For two rats, aim for at least 60 × 40 × 60 cm, but bigger is always better. Height matters more than floor space because rats love to climb. Bar spacing should be 12 mm or less to prevent escapes, especially for young or small rats. Add solid shelves, ropes, and hammocks to break up vertical space and prevent long falls. If you are choosing between two cage sizes, pick the taller one.

Pet rats need a large, well-ventilated metal cage with horizontal bars for climbing. Multi-level cages work best because rats naturally explore upwards. Look for secure door latches, solid shelves, and enough space to hang hammocks and ropes. Glass tanks and small starter cages are not suitable for adult rats. When in doubt, choose the larger cage.

No. Glass tanks are not suitable as a home for pet rats, even large ones. They have poor ventilation, which allows ammonia from urine to build up quickly and irritate rats' sensitive lungs. They also offer no opportunity to climb, which is an important natural behaviour for rats.

A well-ventilated metal cage with horizontal bars is the right choice. If you already have a tank and are waiting to upgrade, increase spot-cleaning frequency and make sure the room is well aired, but treat it as temporary rather than a long-term setup. Some owners do repurpose a tank as a standalone dig box, which is a perfectly good secondary use.

Bar spacing of 12 mm or less is safe for most adult rats. Anything wider risks a rat getting their head or body stuck, which can cause serious injury. Young rats, small females (does), and any rat under around 300 g need the smaller end of that range.

If you are unsure about a cage, test it by trying to push two fingers through the bars side by side. If they fit easily, the spacing is likely too wide for smaller rats. Bar spacing is one of the most commonly overlooked safety details when choosing a first cage.

A perspex base tray is a custom-cut acrylic insert that sits inside the bottom of a rat cage, raising the effective depth of the substrate. Standard cage trays are usually only a few centimetres deep, which limits how much bedding you can use. A perspex tray allows you to build up 15 to 20 cm or more of substrate, which gives rats the opportunity to dig and burrow naturally.

It is a popular modification in the UK rat community and can make a noticeable difference to enrichment, particularly for rats that enjoy digging. Trays are typically made to measure by acrylic suppliers or cut by owners themselves. A glass tank can also be used as a standalone dig box for free roam time, which achieves a similar result without modifying the main cage.

Most rats do best on low-dust, paper-based bedding. Paper pellets or cardboard-based bedding work well in litter areas because they absorb smell and stay put. Avoid pine and cedar shavings, as the oils can irritate rats' lungs. If bedding creates a visible dust cloud when poured, it is not suitable. Aim for around 8 to 10 cm depth where your rats toilet most, and a thinner layer elsewhere.

Yes, plain cardboard is safe for rats and most enjoy it. It is good for chewing, shredding, hiding in, and foraging around. Cardboard boxes, tubes, egg cartons, and tissue boxes are all useful and free sources of enrichment.

Avoid cardboard with heavy ink printing, glossy coatings, or tape still attached. Plain brown cardboard and unbleached card are the safest options. Cardboard is not suitable as bedding on its own since it does not absorb urine well, but as enrichment and nesting material it is a brilliant everyday addition to any cage.

Pet rats are naturally clean animals that groom themselves regularly, and a healthy rat kept in good conditions produces very little odour. They do not smell bad. The smell most people associate with rats usually comes from a dirty cage, not the animals themselves.

Urine is the main source of odour, particularly from unneutered males, who tend to scent mark more than females. Kept on top of, the smell is very manageable. Cleaning the cage a few times per week, spot-cleaning daily, and using an absorbent paper-based bedding will keep smells well under control. Good ventilation matters too, so avoid tanks or enclosures with restricted airflow.

Placing a small litter tray in a corner of the cage and training your rats to use it consistently can significantly reduce the area you need to spot-clean each day.

Yes, unneutered male rats (bucks) do tend to be smellier than females (does). Males scent mark more often, leaving small traces of urine as they explore, and this is usually the main source of odour.

It does not mean males are unpleasant to keep. Good absorbent bedding, daily spot-cleaning and a well-ventilated cage keep things manageable. Some owners choose to have their bucks neutered, which noticeably reduces marking in many rats. Worth a chat with a vet with rat experience if it becomes a concern.

Usually it comes down to two things: not enough bedding and infrequent spot-cleaning. If urine soaks through to the tray beneath, the smell builds fast no matter how often you do a full clean.

Aim for around 8 to 10 cm of bedding so urine is absorbed before it reaches the base. Spot-clean wet patches daily and do a full cage clean every three to five days depending on how many rats you have. Good airflow helps too, so avoid tanks or enclosed units with poor ventilation.

Spot-clean daily and do a full clean every three to five days for a pair of rats. Larger groups will need the lower end of that range.

Spot-cleaning means removing visibly wet or soiled bedding and refreshing litter trays. A full clean means washing down the bars, base and any shelves, then replacing all bedding. Avoid heavily scented or bleach-based products as rats have sensitive airways; a diluted pet-safe disinfectant or hot water works well. Leaving a small handful of used bedding when you restock helps your rats settle back in more quickly.

They can take the edge off background odour in the room, but they will not fix a cage that needs cleaning more often. Think of them as a complement to good husbandry, not a replacement for it.

If you do want one, look for a unit with both a HEPA filter and an activated carbon layer. HEPA captures particles but carbon is what tackles ammonia from urine. Position it near the cage but not directly in front, and choose a model rated for a slightly larger room than you have so it can run quietly on a lower setting.

A good quality rat nugget (lab block) should make up the main diet to keep nutrition balanced. Add fresh vegetables daily and fruit only in small amounts. Fresh water should always be available from more than one source, for example a bottle and a bowl. Scattering part of the dry food around the cage encourages natural foraging behaviour.

Good nutrition starts with rat nuggets or lab blocks as the daily foundation. Add fresh vegetables every day and offer small amounts of fruit a few times a week. Treats should be occasional rather than daily. Always provide clean, fresh water. Keeping the base diet consistent helps prevent selective feeding.

Some experienced owners feed a quality grain mix instead, or make their own, though nuggets are generally easier to manage and reduce the risk of selective feeding.

A few common foods to keep away from rats entirely: raw sweet potato, raw dried beans and lentils, green or uncooked potato, rhubarb, and the pips or stones from fruit like apples, cherries and plums.

Citrus fruit (oranges, lemons, limes) should not be given to male rats as a compound in the peel and pith has been linked to kidney problems in bucks (males) specifically. Blue cheese and other mould-ripened cheeses are also best avoided.

When trying any new food, offer just a pea-sized amount first and wait 24 hours to check for any digestive reaction before giving more.

Peanuts are not toxic but they are not a great choice as a regular treat. Raw peanuts can interfere with digestion, and even roasted ones are high in fat, which can contribute to weight gain over time.

If you want to give a nut as an occasional treat, a single walnut or small piece of almond is a better option. Peanut butter is sometimes used to encourage eating in unwell or underweight rats, but it should not be an everyday snack. A good quality rat nugget as the main part of their diet, with fresh veg alongside, gives them everything they need.

No. Pet rats do not need salt licks or mineral blocks if they are fed a complete rat nugget as their main diet. These foods already provide balanced minerals. Salt blocks are designed for livestock and are not necessary for companion rats.

A small drip is normal, but constant leaking usually has a cause. Overfilling can create pressure that forces water out, and temperature changes can increase dripping. Clean the nozzle regularly and run water through it so the ball bearing moves freely. Check bottle angle and seal fit. Always provide at least two water sources so your rats are never without access if one fails.

Yes, and most rats pick it up fairly quickly. They naturally tend to use one or two corners of the cage to toilet, so you are mostly just working with a habit they already have.

Place a corner litter tray where they already tend to go, and fill it with a paper-based cat litter rather than their usual bedding so they can tell the difference. Pop a little soiled bedding in at first so they recognise it as the right spot. Move any stray deposits into the tray for the first few days and they usually get the idea.

It is actually a good sign. Rats scent mark things they are comfortable with and consider theirs, and that includes you. Being marked means your rat feels at ease, not that something is wrong.

Unneutered males do it most, but females mark too. Keeping a small fleece or cloth on your shoulder or lap gives them somewhere to go that is easy to wash. Most rats settle down as they get older and the novelty of exploring you wears off.

Yes, most rats can learn to recognise their name with a bit of consistency. They have good hearing and memory, and will often turn or come towards you when they hear a familiar sound associated with something positive.

The easiest way to teach it is to say their name each time you offer a treat or open the cage. Short names with clear sounds tend to work best. Most rats start responding noticeably within two to four weeks if the association is repeated daily. Do not worry if they sometimes seem to ignore you; rats respond most reliably when there is something in it for them.

Slowly and on their terms. Pushing a nervous rat to be handled before they are ready will set things back rather than move them forward. Start by simply sitting near the cage and letting them get used to your presence, voice and smell without any pressure to interact.

Once they are comfortable approaching your hand voluntarily, you can begin short, calm handling sessions. Keep early sessions brief and always end on a positive note with a small treat. Most rats come around significantly within a few weeks of consistent, patient handling. Some naturally shy individuals take longer, and that is fine too. They can still have a good quality of life.

Start on neutral ground that none of the rats recognise as their territory. Keep early sessions short and calm, then slowly increase time together as they settle. Do not rush; some introductions take days and others take weeks. Swapping bedding or hammocks between cages beforehand helps rats get used to each other's scent before they meet face to face.

Yes. Rats are intelligent and curious animals that need regular mental stimulation to stay happy and healthy. A rat with nothing to do in a bare cage is likely to become inactive, overweight, or start showing repetitive behaviours like bar chewing.

The good news is that keeping rats engaged does not need to be complicated or expensive. Rotating a few simple items, such as a cardboard box, a tunnel, a rope, or a foraging scatter feed, is often more effective than a cage full of permanent fixtures they have stopped noticing. Changing things up every few days makes a real difference.

Rats are good at hiding discomfort, so small changes in behaviour are often the earliest clue that something is wrong. A rat that is less active than usual, eating or drinking less, sitting hunched, or has lost noticeable weight warrants a closer look.

Other signs to watch for include laboured breathing, discharge from the eyes or nose, a dull or unkempt coat, or any lumps appearing on the body. None of these are causes for panic on their own, but any sign that persists for more than a day or two is worth a call to your vet.

Getting into the habit of a simple weekly check at home, briefly noting weight, coat condition and behaviour, means you are much more likely to spot changes early when they are easier to address.

Respiratory infections are one of the most common health issues in pet rats, so knowing what to look for matters. Early signs include sneezing, clicking or rattling sounds when breathing, and a slight puffing of the fur. You may also notice reddish-brown discharge (called porphyrin) around the nose or eyes. A small amount after sleep can be normal, but larger quantities or discharge that keeps reappearing can indicate stress or illness.

A rat that is breathing with visible effort, sitting hunched and still, or has lost interest in food needs to be seen by a vet promptly. Respiratory issues can move quickly in rats, so early attention makes a real difference. If you are unsure, it is always better to ring your vet for advice rather than wait.

Yes, tumours are one of the most common health issues in pet rats, particularly in does (females). Mammary tumours are the most frequently seen type and, while the word tumour sounds alarming, the majority are benign and can often be removed successfully by an experienced vet.

The key is finding them early. Get into the habit of running your hands gently over your rats during handling, feeling for any new lumps, particularly along the belly and chest where mammary tissue runs. A lump that appears and grows quickly is worth a vet call sooner rather than later. Caught early, many rats recover well from surgery and go on to live comfortably afterwards.

Hind leg degeneration (HLD) is a condition where a rat gradually loses the use of their back legs as they age. It tends to appear in older rats, typically in the second half of their lives, and is more common in bucks (males). The back legs become weaker and may drag, though the rat usually remains alert, hungry, and otherwise comfortable.

It is not painful in itself and many rats adapt well, continuing to eat, interact and enjoy life with some adjustments to their setup. Lowering hammocks, reducing shelf heights, and providing soft bedding on the cage floor helps them stay comfortable and mobile for as long as possible. If you notice your rat's back legs becoming unsteady, a vet check is worth having to rule out other causes and discuss how to support them.

If something feels off, trust that instinct. As a guide, book a vet appointment if your rat has been off food or water for more than 24 hours, is breathing with visible effort or making clicking sounds, has lost noticeable weight, has a lump that was not there before, or is significantly less active than normal.

For anything that comes on suddenly or seems severe, such as collapse, laboured breathing or an obvious injury, contact a vet the same day. Registering with a vet who sees rats before you actually need one urgently is genuinely worthwhile, as not all small animal practices have experience with them. A quick call to describe symptoms is always a reasonable first step if you are unsure.

Rats instinctively hide pain, which makes it genuinely difficult to spot. The most reliable signs are behavioural rather than physical: a rat in pain may sit hunched with their fur slightly puffed, move less than usual, flinch or react when touched in a particular area, grind their teeth in a way that sounds different from contented bruxing, or show a dull, glazed expression. Loss of appetite is another strong indicator.

If your rat seems quieter than normal or is not moving around comfortably, take it seriously rather than waiting to see if it passes. Rats rarely show obvious signs until they are struggling significantly. When in doubt, a call to your vet is always the right move.

Rats do not need routine annual health checks the way cats and dogs do. Their lives are short and fast-moving, and the most valuable thing you can do is learn to carry out basic health checks at home on a weekly basis, covering weight, coat condition, breathing and any new lumps.

Even so, registering with a vet who has experience with rats when you first get them is genuinely worthwhile. Not all small animal practices see rats regularly, and knowing who to call before an emergency saves precious time. Building that relationship early costs nothing and matters a great deal when you need it.

Pet insurance for rats is available in the UK but worth thinking through carefully. Premiums can be comparable to cat and dog policies, and excesses mean smaller claims often cost more to pursue than to pay directly. Many owners find setting aside a small emergency fund each month more practical, particularly as rats have shorter lifespans than other pets.

That said, surgery such as tumour removal can run to several hundred pounds, and for some owners the peace of mind is worth the cost. If you do look into it, check the excess, the annual limit, and that exotic small animals are fully covered under the policy.

This is one of the hardest parts of keeping rats, and it is something most owners will face more than once. Because rats are prey animals, they instinctively hide pain and illness, which means by the time they show visible signs of suffering, they are often already struggling significantly.

As a general guide, it may be time to consider letting go if your rat has stopped eating and drinking for more than a day or two, is no longer able to move around comfortably, seems distressed or in persistent pain, or has stopped engaging with their surroundings and companions. A vet can help you assess their quality of life and make the decision feel less lonely.

There is a saying in the rat community that it is better to say goodbye a week too early than a day too late. It is an act of care, not a failure, and the kindest thing you can do for an animal that has given you so much.

Rats start to struggle above 26°C (79°F) and are at real risk of heatstroke above 30°C (86°F). Unlike us, they cannot sweat, so they have very limited ways to cool themselves down.

Keep their cage between 18°C (64°F) and 26°C (79°F) where possible. During warm weather, move them away from direct sunlight and south-facing windows, and use a fan to keep air moving in the room. A ceramic tile or frozen treat in the cage gives them a way to cool down comfortably.

A simple digital thermometer placed at cage height is the easiest way to keep track. Rooms can feel fine to you but still exceed 26°C (79°F) at cage level, especially on upper shelves or near glass.

A rat in difficulty will look limp or unresponsive, may have reddened skin around the ears, and could be breathing heavily. These are signs to act on immediately.

Move them somewhere cooler straight away and offer fresh water. You can dampen their fur gently with cool (not cold) water, focusing on the ears and tail. Avoid ice or very cold water as the sudden shock can cause more harm. If your rat is not responding normally, contact a vet urgently.

A small thermometer in the room means you can step in before symptoms appear. Acting before temperatures hit 30°C is far safer than waiting for visible signs of distress.

Rats need opportunities to climb, chew, hide, and explore. Hammocks, tunnels, ropes, cardboard boxes, and safe wooden chews all help. Enrichment does not need to be expensive; simple items rotated regularly are often more effective than a cage full of permanent toys. Changing the layout occasionally also helps keep things interesting.

Two of the easiest options use things most people already have at home. The first is a tissue box stuffed with toilet roll tubes packed loosely with paper strips or plain tissue, with small treats hidden inside the tubes. Rats have to investigate and dig through to find the food, and it keeps them busy for longer than most bought toys. Refreshing the hiding spots each time you offer it keeps it feeling new.

The second is an egg tray or egg carton with treats placed in some of the cups and covered loosely with paper. Simple to set up, takes seconds, and most rats work through it enthusiastically. Plain ice lolly sticks can also be scattered through bedding with a little soft food on them as a low-effort scatter forage. None of these cost anything and all of them tap into natural foraging behaviour.

Choose a plain substrate free from additives. Organic topsoil that clearly states it contains no fertilisers, pesticides or wetting agents is a good option. Pet-safe coco coir is another reliable, often lower-dust choice. Avoid multipurpose compost, perlite, slow-release fertiliser pellets, and moisture-control crystals. Provide at least 5 to 8 cm depth, keep it lightly damp rather than wet, and replace every few days or sooner if needed.

Ropes can be useful for climbing, but they need to be chosen carefully and checked often. Use thick ropes made from natural fibres such as cotton, hemp, or jute. Avoid synthetic rope and anything that sheds fibres easily. If you notice heavy fraying, long loose threads, or significant chewing damage, remove the rope straight away. Rope is optional enrichment rather than essential equipment.

For healthy adult rats, aim for at least one hour of free roaming outside the cage each day, though more is always better for active younger rats. Free roam time gives them the space to run, explore and interact with you in ways a cage simply cannot provide, even a large one. Older or less mobile rats may prefer shorter, calmer sessions at floor level.

A rat-proofed room or pen works well. Check for gaps they could squeeze through, cables they might chew, and anything toxic or fragile at ground level before letting them out. Rats that get regular free roam time tend to be calmer, more confident, and easier to handle than those kept exclusively in their cage.

No. Rats are not built for endurance running the way hamsters are. Their natural movement is based around exploring, climbing, and problem solving rather than running continuously in one direction.

Free roaming outside the cage, multi-level layouts, ropes, and platforms all provide more varied and natural exercise than a wheel. A wheel can be optional enrichment for some individuals, but it is not a care essential and most rats do not rely on one.

They can be, but only if the size is right and the rest of the cage is not compromised to fit one in. A correctly sized upright wheel with a solid running surface is safe for rats that choose to use it.

The bigger consideration is space. A wheel large enough to be suitable for rats, at least 16 inches for bucks (males), takes up a significant amount of cage room. For most setups, that space is better used for platforms, hammocks, and climbing routes, which benefit all rats rather than just those who happen to enjoy running.

Big enough for the rat to run with a completely flat back from shoulders to tail. The minimum is 14 inches for adult does (females) and 16 inches for adult bucks (males). If the spine curves at any point while running, the wheel is too small and should not be used.

Many wheels sold as rat wheels are closer to hamster sizes and are not actually suitable for adult rats, even when labelled otherwise. If in doubt, go larger rather than smaller.

No. Flat or saucer-style wheels force rats to run at an angle, which causes unnatural bending through the spine and uneven strain on the hips and tail base. This applies even to large flat wheels. They are not suitable for rats and are best avoided entirely.

Yes, very. Adult males in particular often ignore wheels completely or lose interest as they get older and heavier. It is not a sign that something is missing from their care.

Rats that do not use a wheel are not missing out as long as they have space to explore, things to climb, and regular time outside the cage. Free roaming and a well-set-up cage meet their exercise needs without one.
