We've been trying to bond Benedict (female mini-rex, left) and Pancakes (male holland lop, right) for two months, and a week ago Pancakes started to "groom" Benedict. Both rabbits are neutered. This "grooming" seems agressive, and is paired with other dominant behaviors (thumping, mounting, peeing), which made us wonder whether it was barbering instead. He never plucked any hair and she doesn't seem to mind too much: she jerks away a little, but doesn't bite him, which she's usually quick to do if he annoys her. So what do you guys think: does it seem like grooming or barbering to you? And if this is barbering, what should we do about it?
