Choosing a suitable cage for your hamster(s) should be one of the most important decisions for each hamster owner. Bare in mind that the cage is like house same as for us human. All of us want to live in a safe, comfortable and clean home. Your hamster(s) should have the same rights and it is your responsibility to provide them with suitable living place to keep them happy, active and healthy.There are several factors to consider when selecting hamster cages:-
Cage Size
The cage should have ample room for the hamster to do their favorite activity.. exercise!. For a solitary Syrian hamster, the cage should at least able to fit an exercise wheel and some extra space to live and doing other things. A small box that could act as a bedroom also recommended as the hamster usually prefers to have privacy when goes to sleep.
Dwarf hamsters should need a bigger space as we need to take into consideration that dwarf hamsters prefer to live in groups. So we need a cage that at least could cater for two of them plus spaces for them to play and sleep.
If you are planning to allow your hamster to breed, a bigger cage will be needed. Provide enough room for the hamsters to have their private spaces especially for a pregnant or nursing mother. There are cases when the mother attacks her companions due to overly protective reaction to their litters or maybe due to stress of feeling too crowded. Stress could also cause the mother to eat their litters.
Safety
Barred cages are commonly used as a hamster cage. For this type of cage, make sure the bars are close enough so that the hamsters couldn't slip through. This problem commonly occurs to dwarf hamsters or baby hamsters due to their small body size.
If you have other types of pets such as cats or dogs in your house, choose other types of cages such as aquarium or plastic modular cages rather than barred cages to prevent any unwanted circumstances.
Easy to clean
Choose a cage that will not give you headaches to clean up. A tedious cleaning job could make some people bored and might end up doing improper cleaning or even didn't do the cleaning job regularly enough.
Expandability
Some cages are designed to allow future expansion possible. Usually these types of cages are quite expensive. A simple cage could be expandable up to being just like a castle for hamsters. Unless you can afford it, this feature is rather optional.
