Uh oh. Sounds like there's a problem! Well, from my knowledge, I know that sprinkling baking soda onto the stinky part of the carpet, helps to absorb the smell. Try sprinling baking soda on the carpet, leave it there for 1 - 2 days. Then vacuum it and clean with a carpet cleaner (Resolve is a good one). I haven't tried this with Kitty smells (I don't have a Kitty) but it worked for other terrible odors from other things. I can't guarantee that it'll work for your problem, but I think its worth a try. It worked very well when our carpet stunk so bad we couldn't breathe. What happened was a little girl came to our house and stuffed the toilet with tissue paper (I mean like stuffed the whole roll in for fun). She was only two years old. Then she flushed and flushed and flushed and the toilet got so clogged that all the stinky water started pouring out of the toilet, flooding the bathroom, and went out onto the carpet outside the bathroom door! And it STUNK!!!! It was a disaster! LOL! But she was so cute! Anyway, the baking soda worked for that and we used Resolve after vacuuming it two days later. That really freshened the carpet and gave it a lovely smell! I think it might work for your problem as well. Give it a try!
