Yesterday I brought Bentley in from the run after about an hour and a half because it had started to rain and he was eating lots of grass. I was holding him in my lap on a towel that he likes to cuddle in and I noticed he smelled sort of bad. At first I thought it was a bit of mud/poo stuck to his foot which I thought he would clean himself, but then I turned him over to check and there was a huge ball of poo stuck to the bottom of his tail! :shock: It was like golf ball sized, and was not in pellet form just a ball, it looked like a tumour or something. I took him to the sink and my mother helped hold him while I wiped most of it off, but a lot was caught in his fur by his tail and his "man" area (he is neutered though so it was a bit easier) It didn't all come off so I held him so his butt was hanging down a bit and ran some lukewarm water over it and wiped it off, there was still some left but I put him back in his cage to dry off and he cleaned it himself. What do you think this could have been from? :?
