Hah, this is just a question out of curiosity, but exactly where is a piggy's anus? I know it's at the end of the piggy, that's a no-brainer, but I was wondering where there poop 'comes from'. I hold my guinea pig whenever I can, and I've never noticed poop coming out of where I thought the anus was, and they're always sitting on it when I look. Is there anus by their testicles, or on their rear end? Please don't be disgusted or think I'm weird for writing this, I just want a piggie education!
