I found these fleece throws on cleareance for $3 at Walmart and I'm happy to report they are working out great! The boys usually pee in 2 of the corners and both kitchens anyway. That is going to be revamped by next week. Each end will have a loft kitchen with fleece & mattress pad sewn to fit. Here's one pic but if you'd like to see more of my sweet little babies I put new ones in an album on my profile:crazy:.
