We got two female dwarf russian hamsters a month ago. They have been perfectly happy,but this last week they started fighting. One of them is seriously bullying the other,and now I've noticed her paws have blood on them.
We got the hamsters,cage toys etc at the same time,asked for advice and the shop assistant was happy to send us home with that setup(we added extra house,wheel and feeding bowl),but now i wonder if the cage might be too small.
Is it worth it buying a bigger cage in the hope that more space might stop the fighting or separate them?
