Hamster care: what a family needs to know
Ask your vet about your own pet. This page is general information from the sources below.
Hamster care, from PDSA and others on this page. PDSA says a hamster's eyes can pop out if it is squeezed, dropped or grabbed by the scruff, which is why gentle two-palm scooping matters. PDSA says children should always be watched around hamsters because they can bite. It suggests children feed treats and stroke them in the cage rather than hold them. A grown-up should do the real caring.

How long they live
PDSA says hamsters usually live about 2 to 3 years, and Syrian hamsters tend to live longer than Russian dwarfs.
Home
PDSA says the smallest cage is 100 x 50 cm, bigger is better, with bedding at least 25 cm deep for burrowing. Wheels should be at least 20 cm across for dwarfs and 30 cm for Syrians. PDSA says keep the room 18 to 21 C, away from drafts, sun and noise, and that most shop cages are too small.
Food
PDSA says hamster pellets are the base, plus a teaspoon or two of washed fresh fruit, veggies or herbs each day, and Timothy hay. Skip citrus and sugary fruit and veg, and don't rely on muesli-style mixes alone because hamsters pick out the sugary bits. Water from a bottle with a metal spout.
Company
PDSA says most hamsters live best alone, since keeping them together often leads to fighting. Syrian and Chinese hamsters fight when they meet, and even Russian dwarfs should not share.
Handling
PDSA says hamsters are prey animals and can be frightened. Sit on the floor, scoop one up with both palms, and only handle one that is awake, because a sleeping hamster may bite.
Is it a good pet for children?
PDSA says children should always be watched around hamsters because they can bite. It suggests children feed treats and stroke them in the cage rather than hold them. A grown-up should do the real caring. CDC says children under 5 are more likely to get very sick from germs small mammals can carry, and bites and scratches can spread germs even when they look small.
Washing hands
CDC says to wash your hands with soap and running water after you touch the animal, its cage, bedding, food or water. Children should be watched while they wash. Keep the animal and its supplies out of the kitchen and anywhere food is made or eaten, because germs like Salmonella can be on healthy-looking animals and their things.
The vet
PDSA says to contact a vet if you notice changes in a hamster's behavior or looks, and to have any new lump checked.
Good to know
PDSA says a hamster's eyes can pop out if it is squeezed, dropped or grabbed by the scruff, which is why gentle two-palm scooping matters.
A job for the children
With a grown-up, hand-feed a treat through the cage and help pick safe, washed veggies.

Hamster facts
Hamster: facts from the sources below, in the sources' own words.
- Cats and dogs in the home can stress a hamster, so other pets must not reach its cage.
- Hamsters live indoors because it is too cold outside.
- Do not handle a hamster when it is resting or sleeping.
- Leave a new hamster alone for a day or two before handling it.
Hamster card
Hamsters sleep by day and play by night, so they need a quiet day and a calm, careful grown-up in charge.
- Home. A big, escape-proof home with deep bedding to dig in, a solid floor, a dark nest box, and a big solid wheel.
- Food. A balanced hamster mix, scattered so it can hunt for it. A grown-up chooses safe extras; grapes and rhubarb are left out.
- Water. Fresh, clean water always. Check the bottle for leaks or blocks every day.
- Every day. Say hello in the evening. Check food and water, and watch how it eats and moves.
- Every week. A grown-up checks its teeth, coat and eyes. Clean the home when it is awake, keeping some old bedding.
- Handling. Never wake a sleeping hamster. Let it sniff you, then cup both hands and hold it low over a table.
- Happy signs. Digging, carrying food to the nest, running on the wheel, and sniffing every corner at night.
- Tell a grown-up if. Not eating, hiding more, or a messy bottom. A vet who knows hamsters can help.
