I need some advice for my friend who is the momma of two rabbits: a large brown rabbit who's a male and a small blackish rabbit which is a female. The two are kept in separate cages which are next to each other. Recently the female has gone up to the edge of her cage to preen the large brown rabbit. She's licking his nose (and he loooooves it) and every once in a while chews off one of his whiskers. My friend is driving me and her vet crazy trying to understand her behavior. Why does she chew off his whiskers? And why is she preening him? Is this love? I know my ducks and geese but rabbits are a complete mystery to me. You all are the smartest animal people I know. Any ideas are appreciated.
