I had Cain neutered on the same day as his father about a week ago. His father is FANTASTIC! No more pills and he is so well behaved. Cain is the exact opposite. He leaves his pills everywhere and he has become so aggressive. He is charging the bars of his cage when the other rabbits are allowed to run free. Not to mention his spraying! There are arches of urine all over the floor and walls. If he sprays me one more time on the face...:XWhen will he start acting like a neutered rabbit?!
