YES!! They will castrate each other and a particularly aggressive doe has been known to castrate bucks also. (This is the reason you put the doe in the bucks cage and stand there and watch and then remove doe after she is bred.)
Yes, females and males will fight with each other. They have small fights that are just a pecking order. The males can hurt each other if there is a female to fight over.
each other
it really depends what gender ur bunny is. if they are both males, i suggest u separate them immediately. they could hurt each other. if one is a male and the other is a female, the male might be saying "I'm in charge" if both are girls, they may be playing or one might have annoyed another. Every rabbit should have it's own cage. Rabbits are very territorial and need and want their own space. They will fight for territory. it is very dangerous for your rabbits to be caged together. They can and will hurt each other. They will pull fur, bite toes, scratch eyes, slit ears and in the very worst case scenario, they will castrate each other (2 bucks or a buck and a doe) or kill each other.
They don't. They lick themselves and each other. They don't pull out each other's hair.
by communitcating with each other
They Liked to eat fish Dew dew and they stored it on kangaroo pouches,they entertained themselves by putting each other's feet on each other's hed.
the shoot each other
They do it themselves if they like each other.
You should never have 2 male rabbits (Bucks) together. They'll fight and they might kill each other.
You grab up each "one" separately. Take a sharp knife and cut a slit about two or three inches. Pull it out being careful where to cut the chord. Do the same to the other one.
There are some animals which depend on each other to live. Like....ants. They provide shelter for themselves and each other.
