This thread gave me a chuckle. :) I'm the opposite of OP, I love all the poop jokes. As a dog owner, stepping on something is pretty unavoidable, so I thought it was a nice little touch. Like others have mentioned, though, there are ways to freeze need decay for pets and that'll stop them from pooping.
@SuperCoolRachael It's absolutely OK to feel the way you do. OCD is no joke and nobody here thinks you're an uptight loser. I hope you've found a way to get rid of the poops.
