I'm sorry. I'm a live and let live kind of guy and I don't take the moral high ground on many issues but that kind of thing turns my stomach. The animal does not know what is happening to it, so it is a non-consent issue. No matter how you look at it, you are bringing harm to that animal. If someone was going to sexually abuse an animal they may as well be kicking it or stomping on it. It's all abuse.
