Can you put male hamsters together?

Male hamsters should not be housed together under any circumstances, except when they are pups and are still dependent on their mother. As they grow older, male hamsters reach maturity and become extremely territorial. They will defend their territory from any other male hamster, and serious injuries or even death can occur.

To prevent fighting, male hamsters should always be housed separately in single cages. Each cage should provide the hamster with plenty of space to exercise and explore, as well as ample hiding places to retreat to when they feel stressed. By following these tips, you can help ensure the safety and well-being of your male hamsters.
