Understanding hamster behaviour

They will need:

  • To sleep undisturbed during the day.
  • Predictable lighting times - keep them in a room where the lights aren't left on until late at night, and where regular hours are kept.
  • Plenty of space to play and exercise at night. Wild hamsters are usually only active at dusk and night-time and can run up to 5 miles a day. 
  • A running wheel - this will help them exercise, but it shouldn't be the only form of enrichment you give them. Wheels must be good quality with a large diameter, such as one intended for rats. They'll need to be a solid structure and axle-free, and should ideally have a non-slip running surface. As your vet for advice if your hamster develops sore feet while using the wheel and remove it temporarily.   
  • A deep layer of litter in which they can dig and construct a burrow (read more in our guide home cages for hamsters).  

Always supervise your hamster if you let them out of their cage (when they've become tame) to make sure they don't stray or get up to mischief. If you have another pet, such as a dog or cat, make sure your hamster is safe from them. Never leave your hamster out of its cage unattended or overnight.

Hamster hibernation

Wild hamsters hibernate during the winter but wake up periodically to feed. Keep your hamster warm during the winter, as this will help stop them going into hibernation. While hamsters can hibernate with no issues, some owners have reported concerns.

If your hamster does go into hibernation, make sure they're in a warm (but not too hot) place and they should wake within a short period. Make sure they have plenty of fresh water, fresh food and nesting material, and check them regularly. If you're at all unsure, contact your vet for advice.
