Stopped in Petco yesterday (where our shelter bunnies live) and saw a bunny in the back room that was dropped off (as a give away). He was caged with a guinea pig (when brought in)and the owner said that he had eaten nothing but guinea pig pellets. I took the bunny out and looked him over..he is very thin and has lost most of his hair on lower part of body. We have a guinea pig with mange at the shelter so I know what mange looks like. The hair loss looks similar however the skin of the bunny is smooth and clean and he doesn't appear to be scratching. I can't afford to take this bunny home nor to the vet although Petco said they will be very picky about who getshim and will only adopt him out to someone willing to get him veterinary care. He is getting hay and rabbit pellets now and I will give him some greens when I go in the store. This bunny is either older or just tired from a horrible life. His eyes look "tired. " Petco knows me well as I am over there alot. They will let me help this bun as much as I want..what more can I do?
