Okay, so we have two male rabbits, both about 8 months old. They were neutered about a month ago (maybe more). They are normally pretty docile, and although they've chased each other the odd time I've never seen them behave aggressively toward each other. Until today. Yesterday they were fine, today they're like two feral animals - biting, scratching, grappling with each other, tufts of fur flying everywhere. I have no idea what's got into them. I have separated them for the time being. Does anyone know what could be going on with them? Hate to see them like this
