My DH left the carrier on the floor and now our cat has peed in it. I'm so extremely irritated and am now looking for replacing straps for it, as they're the only thing that can't really be washed in it. I found that I can order replacement parts on the Graco website, but I wanted to make sure I was ordering the right piece. Is it the harness assembly that would have the strap/seatbelt parts?? I know this is a dumb question.
