I've thought about those too,

It's crewl in a way, but if I had to choose I'd go with pericing an ear instead a tattoo. But I'll never do it either unless I buy a pet that's already had a pericing done and it's too late. I seen a bunny (BIG Lion head) with a periced ear, this girl was holding him I never thought of the pain as I think getting your ears periced is a fast thing, altho I don't know as I've never gotten my ears periced lol. I know pet's are not accessories but just because someone has a tattoo or periced pet does not mean they don't love them just as anyone else, maybe they never thought of the pain when getting it done or maybe they got them that way.
