I have two female bunnies they've been together since they were just weaned they were in the same cage with one male when they were both pregnant the male went in a different cage he got out and got killed by our dog we put both females in different cages they were very aggressive to each other they r not pregnant but still aggressive to each other one starts gently pulling out out the others hair and eating it they r calm at first then all of the sudden they start fighting we would really like them to get along and every time they r close to each other they chew and eat on all types of material
