Ewe: ya it isnt ideal but I keep it really clean and also she isnt voiding much so there is no real issue. She isnt eating very much so there is next to no waste. I think the drugs were effecting her appetite too. Shes a really large cat so no issues with her losing a pound or two anyway.

wetware. Very sound advice. We had a cat who peed on our bed at one time. Talk about constant washer and dryer going. We used to put plastic on the bed but she just peed on that. I didnt think to use foil. They hate the sound and feel of that. If I ever have that issue again I will try that..
I found that keeping the box extra clean encourages frequent use. Cats do not like stinky boxes. In my house it is a part time job cleaning all 4 boxes 4 or 5 times a day but well worth it.  Keeping boxes in private areas helps promote frequent use as well. I have one friend in a bachelor apartment that put up a chinese screen around her cat's box so the cat has privacy! LOL

The things we do and put up with for our fur babies.
