Is it possible for my rabbits to be behaving better just five days after their neutering? I have already noticed Fred is not leaving droppings in the corners of his cage anymore, which I think he used to do to mark his territory. The vet told me to keep them quiet and in their cages for five days so today was the first day they have been out in their exercise pen. It seemed like they were better about being picked up to move to the pen. Not perfect, but Fred didn't nip at me like he used to.
