Rehome Pets
Who can live alone, and who cannot
This is the first thing to get right, because it determines whether you are rehoming one animal or a group, and getting it backwards causes real harm.
| Animal | Housing | Note |
|---|---|---|
| Guinea pigs | Never alone | Highly social; rehome in their existing pairs or groups |
| Rats | Never alone | Very social; keep same-sex groups together |
| Mice | Females in groups | Males often must be housed singly due to fighting |
| Gerbils | In pairs or groups | Established pairs should not be split |
| Syrian hamsters | Always alone | Solitary; housing two together causes serious fighting |
| Chinese hamsters | Usually alone | Generally solitary as adults |
| Ferrets | Best in pairs or groups | Social, and need far more space and time than most expect |
State the correct answer for your animal in the listing. A surprising number of adopters do not know that Syrian hamsters must live alone, or that a single guinea pig is a welfare problem.
Preparing your pet
- Check for the common problems. Overgrown teeth and nails, wet tail in hamsters, mites, lumps in older rats, respiratory noise. Small mammals hide illness and deteriorate fast, so an exotics vet check is worthwhile if anything seems off.
- Separate any mixed-sex groups before rehoming, unless you intend to hand over a pregnancy you have not disclosed. Accidental litters are extremely common in small pets.
- Ferrets: confirm vaccination status, which is required in some countries, and note whether they are neutered or implanted.
- Guinea pigs: note the vitamin C supplementation, since they cannot synthesise it and this is a very common gap in new owners' knowledge.
- Write down the food brand and amount, bedding type, cage setup, handling tolerance, and waking hours.
Writing the listing
- Photograph in natural light at the animal's level, and include a shot of the current housing.
- Give the species precisely — "Syrian hamster", "Roborovski hamster", "Abyssinian guinea pig".
- State age, sex, and whether neutered. Age matters: hamsters live two to three years, so a one-year-old is middle-aged and adopters should know that.
- Say whether the animal is hand-tame, tolerates handling, or is nervous — all are placeable.
- If they are a bonded pair or group, say so in the first line and state that you will not split them.
- Say what housing you require. "Needs a cage of at least X" filters your inbox usefully.
- Say what is included, and give your reason for rehoming.

Screening adopters
People screen small pets far less carefully than dogs and cats, which is precisely why small pets end up in bad situations. Ask the same questions you would ask anyone:
- What cage do you have, and what size is it?
- Where in the house would it live? (Near a television or in a child's bedroom is a poor answer for a nocturnal animal.)
- What would you feed?
- Do you have other animals of this species? Same sex? How would you introduce them?
- Do you have cats or dogs, and how would they be kept away?
- Have you kept this species before? What happened?
- Which vet would you use, and do they see small mammals?
- Who is the pet for, and who will actually do the cleaning and feeding?
- Are you aware this species lives roughly X years?
Ask who will do the care, not who wants the pet. With small animals these are frequently different people, and the placement depends entirely on the answer to the first question.
The feeder-animal problem
This is the specific risk for small mammals. Rats, mice, gerbils and hamsters advertised free are actively sought as live food for reptiles and birds of prey. The signals are consistent: wanting several at once, asking about weight or size rather than temperament, no interest in the individual animal, no questions about care, no housing to describe, refusing a home visit, and wanting collection today.
You do not have to accuse anyone of anything. Just ask what housing they have, who the pet is for, and whether you can see where it will live — and decline politely if the answers do not add up. Never use the phrase "free to a good home"; it is the exact term these enquiries search for. See what rehoming costs for how to word it instead.
Transport and settling in
- Move the animal in a small, secure carrier with familiar bedding — not a cardboard box, which rodents chew through quickly.
- Keep bonded animals together in the same carrier.
- Keep the journey short, the car at a moderate temperature and out of direct sun. Small mammals overheat very fast.
- Send the current food and some used bedding. The familiar smell genuinely reduces stress, and an abrupt food change causes digestive upsets in guinea pigs in particular.
- Hand over the written care notes and any veterinary records.
- Advise the new owner to leave the animal alone for two or three days beyond feeding and water, then begin handling gradually. Waking a sleeping hamster to show it to visitors on day one is how people get bitten and how animals get labelled aggressive.
Frequently asked questions
Which small pets must be rehomed in groups?
Guinea pigs, rats, mice, gerbils and most degus are highly social and should not be kept alone — rehome them in their existing groups or pairs. Syrian and Chinese hamsters are the opposite: solitary, and housing them together causes serious fighting. Say which applies in your listing.
How long does it take to rehome a small pet?
Usually one to four weeks. Guinea pig pairs, rat groups and ferrets take longer because they need more space and a more committed keeper. Older animals and those with health problems also take longer.
Should the cage go with the animal?
It helps if it is an appropriately sized cage, because familiar bedding and furniture reduce stress. If your cage is undersized — as many pet shop cages are — send only the bedding and hideaway, and ask the adopter to confirm what housing they have.
How do I avoid my small pet being used as snake food?
Never advertise small animals as "free to a good home", and be cautious about anyone wanting several at once, asking about weight or size, showing no interest in the individual animal, or refusing a home visit. Ask what housing they have and who the pet is for.
Are small pets suitable for young children?
Less often than people assume. Hamsters are nocturnal and bite when woken, gerbils are fast and hard to hold, and most small mammals are easily injured by being dropped. Guinea pigs and rats generally tolerate gentle children best, but all need an adult who takes real responsibility for the care.
