Wow, I know this feeling. I rent a room out of my buddy and his wife's house (he and I are USMC). About a month ago I left my room's door open for just a couple minutes as I was in the process of doing laundry, so I had just stripped my BRAND NEW $1000 beautiful sealy pillowtop mattress of its' sheets and matress protector. His wife's cat ran in while I was setting up the wash in the garage, pissed on the mattress and shat in the blankets that were on the floor. Soaked my damn mattress about a foot circle.
Worst. Smell. Ever.
So she was out of town,

and my buddy was pretty tired of having it around too, so we took care of the situation in a quick humane fashion.
But if it had scratched my SS in the garage, i would have literally lost my mind and done something heinous to it.:slice:
Cats are wicked little turds, dude. Seriously I think they are evil.
Sorry to hear, hope your baby gets well.
