By Dr Duncan Houston
A new rabbit hiding in a tunnel or a hamster waiting until dark to explore may simply need time to feel safe. A small pet that stops eating, struggles to breathe or becomes weak needs a different response.
A good homecoming gives your pet familiar food, suitable housing and control over contact. This guide focuses on rabbits, guinea pigs, hamsters, rats and ferrets, because their diets, social needs and warning signs are not interchangeable.
Quick Answer
Prepare a secure, species-appropriate home before collection, keep the initial routine quiet and let your new small pet approach you voluntarily. Preserve familiar food and established compatible companions, while keeping unfamiliar animals apart until you have an introduction plan. Check eating, droppings, movement and breathing from arrival; do not dismiss appetite loss or weakness as settling-in stress.
What should you prepare before bringing a small pet home?
Ask the rescue or previous carer for the exact food and feeding routine, medical records, known handling preferences and details of existing companions. Confirm the animal's species, sex and reproductive status rather than guessing. Arrange a veterinary practice that treats that species and find out who provides emergency care.
Set up the permanent enclosure or a suitable settling area before travelling. Check door catches, gaps, electrical cables, accessible medicines, cleaning products and anything that could be swallowed. A small carrier is for transport, not a substitute for an adequately sized living space.
- Give them somewhere to retreat. Provide accessible shelters without forcing the animal to remain visible.
- Make essentials easy to find. Place familiar food and functioning water containers near safe routes between resting areas.
- Check the room as well as the enclosure. Avoid direct sun, temperature extremes, smoke and persistent noise.
- Plan safe movement. Provide suitable flooring, exercise space and species-appropriate opportunities to explore.
Guinea pigs need several refuges, a comfortable environment and regular access to exercise. Familiar objects and travelling with their established companions can also make a move less disruptive. See the RSPCA's guinea pig housing and transport guidance.
Which parts of the plan depend on the species?
| Animal | Important difference | Homecoming priority |
|---|---|---|
| Rabbit | Needs a fibre-rich diet and appropriate rabbit companionship. | Keep hay available, protect exercise space and preserve an established compatible bond. |
| Guinea pig | Needs dietary vitamin C and compatible guinea pig company. | Use its own appropriate diet and provide enough shelters and feeding access for every animal. |
| Hamster | Companionship rules differ from social rodents. | House Syrian and Chinese hamsters alone; do not add an unfamiliar hamster as a welcome gift. |
| Rat | Needs compatible rat companions and gradual, positive human contact. | Preserve a stable group and let the rats investigate you in their own time. |
| Ferret | Is an obligate carnivore with different food needs from herbivores. | Provide its familiar appropriate diet and carefully secured exploration space. |
The Merck Veterinary Manual's rabbit nutrition guidance explains why dietary fibre matters. Ferrets need animal-based nutrition, as described in Blue Cross's ferret care advice. Do not offer one shared bowl of food to different species.
The RSPCA explains the different companionship needs of hamsters and rats. A solitary hamster does not need a cage mate simply because a rat does.
How should the first few days work?
Use a secure, ventilated carrier suitable for the animal. At home, place it within the prepared secure area and allow a safe exit when possible. Do not tip the animal out or pass it between family members.
Keep visitors and optional handling to a minimum. Sit nearby, speak gently and allow the animal to choose whether to approach. For hamsters, Blue Cross recommends minimal disturbance during the first two or three days, apart from necessary care. Quiet settling still includes checking that the animal is well.
Maintain the familiar diet initially unless your vet advises an urgent change. If it needs improving, plan the transition with the rescue or vet. Introducing new food, a new enclosure and intensive handling together makes it harder to identify why an animal becomes unsettled.
During each care check, look for food actually eaten, fresh droppings, urine, comfortable movement and easy breathing. A full food bowl alone tells you little, and food disappearing into a hamster's store does not necessarily show how much it ate. Record observations so that another household member knows what has changed.
Is hiding normal, or is my new pet unwell?
Interpret hiding alongside physical signs. Retreating when someone enters the room is different from remaining hunched, barely moving and leaving food untouched. Stress can affect behaviour, but pain, dental disease, digestive problems, respiratory illness and unsuitable housing can look like nervousness.
| What you notice | How to interpret it | What to do |
|---|---|---|
| Uses a hide but eats, passes normal droppings and moves comfortably when undisturbed | Compatible with cautious adjustment. | Keep the routine quiet and continue checks at care times. |
| Repeated escape attempts, fighting or one animal prevented from reaching food | The environment or social arrangement needs attention. | Remove the immediate hazard and contact the rescue or an appropriate behaviour professional; seek veterinary care for injuries. |
| Eating less, fewer droppings, drooling, diarrhoea or unusual inactivity | Possible illness, not a reliable sign of ordinary settling. | Call a species-experienced vet promptly. For a rabbit or guinea pig that stops eating, call now. |
| Difficult breathing, collapse, seizures, major injury or severe weakness | Potential emergency. | Contact an emergency vet immediately and arrange transport. |
Guinea pig dental and digestive disease can cause appetite loss, and breathing problems may deteriorate quickly. In rabbits, gut stasis and intestinal obstruction can both be serious. A vet may need an examination and imaging to distinguish them. Offering a favourite treat cannot rule either out.
When is this an emergency?
Seek immediate veterinary help for breathing difficulty, collapse, seizures, severe pain, major bleeding or an animal that is cold and poorly responsive. Do not assume a cold, motionless pet needs time to become emotionally comfortable.
A ferret straining without passing urine, staggering or becoming profoundly lethargic also needs urgent attention. The Merck Veterinary Manual lists these among ferret emergency signs. For changes in eating or drinking, the RSPCA advises contacting a vet straight away.
Phone ahead, minimise handling and transport securely. Do not give human medicine or force food or water into a weak, struggling animal. Ask the vet what to do during the journey.
How should you introduce other animals and children?
Keep unfamiliar animals separate initially and ask your vet or rescue about health screening and the right introduction process. Do not exchange bedding while disease precautions are still being assessed. An established compatible pair arriving together is a different situation from two strangers meeting for the first time.
Rabbit introductions should be gradual and supervised in appropriate neutral space, as described by the RSPCA's rabbit companionship guidance. Guinea pigs need their own compatible companions. Housing rabbits with guinea pigs creates dietary, injury and disease concerns.
Do not arrange face-to-face meetings between prey animals and dogs, cats or ferrets as a settling exercise. Keep secure physical separation and prevent other pets from staring into, pawing at or climbing on the enclosure.
An adult should supervise children. Start with watching and helping prepare supplies. Let the animal approach at floor level; do not chase it from a shelter or restrain it for cuddles. Learn the correct lifting technique for that species before necessary handling.
What should you do next?
- Today: confirm secure housing, familiar food, working water access and a quiet retreat. Save the vet's contact details.
- At each care check: note eating, droppings, urine, breathing and activity. Check each animal individually in a group.
- As confidence improves: introduce short voluntary interactions and simple suitable enrichment. Increase one challenge at a time.
- Arrange the first veterinary assessment: book promptly after arrival, with timing based on age, records and health. Symptoms override any routine appointment date.
- At the appointment: discuss diet, body condition, dental health, preventive care, reproductive management and any introduction concerns.
Common mistakes to avoid
- Waiting 48 hours for appetite loss or severe inactivity to resolve.
- Forcing frequent handling because you want the pet to bond quickly.
- Assuming every small mammal needs the same food or companions.
- Replacing all familiar surroundings and introducing many new treats at once.
- Using a fixed weekly deep-clean schedule for every species, regardless of soiling, bedding type or disease-control needs.
How can you keep building confidence?
Keep care times predictable, remove soiled material regularly and adapt cleaning to the species and enclosure. Preserve clean familiar items when appropriate, but follow veterinary disinfection instructions if illness is suspected.
Provide daily opportunities for suitable movement and natural behaviour: safe foraging, tunnels, shelters or supervised exploration. Introduce new experiences gradually and watch whether your pet approaches willingly. Comfortable eating, resting and movement are more meaningful early goals than accepting cuddles.
Frequently asked questions
How long does a new small pet take to settle?
There is no reliable deadline for every species or individual. Judge progress by comfortable eating, normal droppings, exploration and less fear. Do not use a settling period to explain away signs of illness.
Should I handle my new pet on the first day?
Keep handling to what is necessary for safe care. Allow voluntary contact and learn the appropriate handling technique before lifting. Some animals enjoy interaction without enjoying being picked up.
My new rabbit is hiding and not eating. Should I wait?
No. Contact a rabbit-experienced vet now. Reduced appetite with fewer droppings needs prompt assessment even immediately after a move.
Can my new guinea pig live with my rabbit?
Do not introduce them as housemates. Their communication, nutrition and health risks differ; arrange appropriate companionship within each species.
Should I buy a companion for a new hamster?
Do not add an unfamiliar hamster. Syrian and Chinese hamsters should live alone. Ask a knowledgeable rescue or vet about the needs of your particular hamster.
