CAGE AND EQUIPMENT FOR YOUR HAMSTER

Hamsters are expert escapers

Hamsters are expert escapers

All pet golden Syrian hamsters, (Mesocricetus auratus), should be housed on their own. If they are housed in groups (as they are in some laboratories), they often fight and their health suffers (Kortz & Gatterman, 1999). Do not ever put hamsters with pet gerbils or pet mice or pet rats. (There are different smaller hamsters who do like living in groups, but this page does not deal with their needs.)

Small cages make hamsters chronically stressed (Kuhnen 1999)  and develop bad habits (Normando & Gelli 2011) so buy the biggest cage  you can afford. Hamsters like more space – at least 10,000 square centimetres (Fisher et al., 2007). It must be tall enough for them to rear up on their back legs, a minimum of about 6 inches high at the very least. Hamsters kept in small cages are more likely to gnaw at the cage bars, a habit which usually shows that a hamster is bored or unhappy (Gerber et al. 2008).

They need complex, not bare, space.  Hamsters in a cage with lots to do are more optimistic than those in small barren cages (Bethell & Koyama 2015). As hamsters like climbing, a two-tier cage may give them a chance to do this. Try to buy a cage without a fixed wheel already in it, as often wheels in cages are too small. Buy a relatively large wheel separately and fix it securely.

Some all-plastic cages, including the sort with tunnels, may look good but have poor ventilation. If a hamster gets fat it may get stuck in the tubes.  These are best used for temporary recreation not for a permanent home. Fish tanks are not suitable either because of poor ventilation. Make sure any cover on a cage fits properly as hamsters are escape artists. Females grow larger than males so be careful to get big enough cage fittings.

Hamsters do not like bare plastic or wire floors (Sherwin 2007, Arnold & Estep 1994) so cover wire flooring with cardboard and provide litter for a bare plastic floor. Hamsters like digging tunnels and so the deeper the litter (if it’s the sort they can tunnel in), the better (Hauzenberger et al., 2006). Try to buy a cage which allows them to dig into the litter (RSPCA 2013).

The cage should have a water bottle with nozzle and a small bowl for food – though scattering the food is better. Bottles should be sterilised and refilled once a week and bowls washed once a week. A hamster will consume 5 ml of water per 100 g of body weight per day (Gibson & Brady 2000). Make sure the nozzle is at a height the hamster can easily reach.

Within the cage hamsters like a little house or shelter for them to sleep in, preferably in wood with a flat top to sit on. Plastic shelters can make for condensation (Adby & Neill, 2004) and a pitched roof means the hamster cannot enjoy climbing on top of the shelter.  The shelter must have a dark corner where they can sleep – just a little arch (sometimes sold) doesn’t give enough privacy.  They will often store their food there and quite often they will urinate there (Gerber et al. 2008).

If for some reason you can’t give them a shelter then there must be masses of bedding so that they can make their own shelter/hideaway out of it (Gerber et al. 2008.) Wild hamsters live in burrows, so making a tunnel in the bedding is the next best thing for them. Ideally they should have a shelter, as well as much bedding as they like.

Locate the cage away from loud noises, which can give hamsters high blood pressure and convulsions (Russell 2002). The temperature should be 20-24º C or 68-75 F. Your hamster, because he is nocturnal, should have 10-14 hours of darkness (Gibson and Brady 2000). Therefore do not put the cage in bright sunlight where the temperature can get too high – this is particularly important for cages with solid sides. Do not put it close to a light or on a windowsill. Keep the cage away from draughts or temperature extremes. Car fumes in a garage may make the little animal ill.

Bedding is crucially important for hamsters so read the page on Best Bedding and Litter for your hamster. All hamsters need toys and things to do – read the page on Keeping your hamster Busy not Bored.
