The semi domesticated cat that I house and feed somedays just threw up somethings intestines and bits of fur right next to me at the computer... The smell is intense...
So you never specified if you cleaned it up, or just left it there. And tell that cat to clean it up himself, and get a job and start payin some damn bills around here!
I wonder when you own a cat, what color carpet do you get? Do you see what color the puke is and get carpet that color and then never, ever change the cat food you get? Just wondering? lol.
The carpet throughout the house was to begin with about 10 different colours in an alternating line pattern... even if you happen to get a little stain unless you're looking hard for it you can't see it... it's a blessing for having pets...
