I have a male rabbit who has teeth problems, so the vet did surgery for that. Because he was never neutered prior, they decided to do that as well while he was under. Now he has a cone because he was licking so much that he opened up one of the incisions a tiny bit. They glued it back, but the cone freaks him out and he won't move or eat with it. We tried a kind of vest thing the vet gave us, but he can lift it up if no one is around (worried about at night). Any other options or ideas to keep him from opening it up again?
