can't do it yet
I still haven't brought myself to clean up the last papers Xena peed on. She was one of those weird female cats that spray, and she had a very distinctive, sweet scent. Before the second-to-last trip to the vet, she let go while lying on an old gift bag and some tissue paper in the corner. It took me a couple days even to notice, and I know it will turn stinky eventually, but for now it's just like an odd, not quite floral perfume in my room.
