Junior Guinea Pig
hi, I have 2 female 2 year old pigs , they're sisters and have always lived together ( I got them a few months ago from a vetinary college) but they've started fighting a lot , biting , pushing each other around and making a lot of grunting noises etc. Any ideas why this might be happening now and what I can do about it? I also have 4 other pigs living in the same room.
