The ideal cage for your hamsters should consist of at least two levels and should be filled with plenty of toys, places to rest, and stimulating accessories. Hamsters tend to easily get overweight, so an exercise wheel is mandatory. However, try to keep away from wire wheels as your hamster can get its feet stuck in it. Opt for those made of sturdy plastic instead.
Tubes are also a great choice and most hamsters will love them. Just make sure they are made of rough plastic to resist chewing. Avoid cloth accessories and toys for the same reason – your hammies love chewing.
