You can keep dwarf hamsters together but you should increase the size of the cage accordingly. You should house Chinese and Syrian hamsters in separate cages.
These holes will allow you to attach the wire mesh on the lid of the cage.
Mesh will keep the cage ventilated without allowing space for your hamsters to escape. Use wire cutters or a strong pair of scissors to cut the wire mesh.
Wiping down the cage with the bleach solution will prevent your hamster from getting sick from any harmful chemicals that may get on the bin when it’s being manufactured.
Don’t pack down the bedding so the hamster can burrow through it, use around 6-7 inches Avoid using pine and cedar shavings because it can give the hamster splinters and injure it. Use dye-free bedding to prevent your hamster from getting sick.
Get a 6. 5 inches (17 cm) wheel for dwarf hamsters and get an 8 inches (20 cm) wheel for Chinese, Syrian, and other large hamsters.
Do not fill a bowl with water because you hamster could drown.
Hamsters will store food in their cheeks and hide it around the cage. Replace fresh food, like fruit, every day to prevent it from getting moldy.
Keeping your hamster cage clean will prevent your hamster from getting sick and will stop bad odors from forming.
