We have a ongoing rule in our house when it comes to buying anything, can/will the cats chew, break, wreck, cat fluids stain etc. Which has stopped me from buying a few nice things.
Unfortunately our Lirael loves to chew on wood, plastic, carpet, books, miniature figures etc, Gizmo is more picky and will only go for things made of paper....
Which explains when I want anything from my underwear drawer I have to move books, newspapers and magazines before I can find anything.
The only pee problem we have is catnip, we can't have anything in the house with it or Penguin pees on it which last time stained my new suede chair, the time before he actually peed on me so I'm not sure if that was a step up.
Just hang in there.
