Its better for you to separate the hamsters if they are fighting.
They'll fight, and keep fighting until one of them dies....
You will soon have many Hamsters.
They will kill eachother. You will end up losing both of those hamsters if you keep them together so my advice is to seperate them immediately!
It is because hamsters don't like roommates. Unless they're a boy and a girl when they squeal it means they hate each other. They are possibly fighting.
Never put two males or females in a cage together. They'll compete with each other.
When they start fighting.
get one more cage
most hamsters fight when another sex is in there or you may think there fighting when there breeding.......
hamsters are fighting when there start to be like scratches and bite marks and some times bite you or your friends my hamsters where fighting and i separated them and some times they will attack each other and they will make funny noises like squeeling hope this helps.
separate them they may get injured if they always fight.if they do get injured go to the vet
"I have two hamsters" there you go, have fun!
some hamsters like to be alone. They mostly fight with other hamsters that are not the same species as them. You should put them in different cages if they keep fighting because they can die.
