I hope your bunny is okay. It’s such a worry when there’s something out of whack and you don’t know why.
Btw, I have four bunnies, two males, two females, and every one of them hump the cats. They seem to all prefer short haired black and white Kirby to long haired all white Marshmallow.
But in a pinch they don’t really care who’s who. I have one bunny who’s hysterical! He knows that Kirby hates him for trying to hump her, but he still tries. She retaliates by giving him a good wallop on the head, (her claws are clipped), and so RaisinBun does this thing where he crouches very close to the floor and makes himself as flat as possible. Then, he scootches forward juuuuust the tiniest bit. Then he waits. Kirby is motionless, with her paw up and ready. Nothing happens, so he scootches just the tiniest miniscule bit again. Waits, nothing happens. Scootch, wait. Scootch, wait. Scootch, WHAUMP!!!!. Okay, run away, lol.
So funny. He never learns, silly babbit.
Keep us updated on your little one. Hope she’s okay.
