Hamsters are solitary animals, so this is normal.

Hamsters are very territorial animals, and they are very hostile to any of their own kind that enters their territory.

Because it may be an intruder coming to occupy your territory.

The territoriality of hamsters is better when they are young, and when they become adults, they are in heat. This kind of territoriality becomes more and more intense, and anyone of the same kind who enters the territory will become a target.

We have always said that there is no room for two tigers in one mountain. This is what we mean. Tigers are also solitary animals, and so are hamsters.

There is no room for two tigers in one mountain, unless the idea of ​​one male and one female is wrong. Tigers can only be together when they are in heat and can mate for a short period of time. They will be separated immediately after mating. In this case, some tragedies will occur.

The same goes for hamsters. Hamsters in estrus can mate together for a short time, but they cannot be together for a long time.

There are very few hamsters raised in shared cages, and very few of them get along well. I have been raising hamsters for 11 years, and I have found two or three pairs. Are there other caged ones...

In the end, one of them was missing? Half.

So, don't try it, the result will be very tragic.
