Hello nique517 and Welcome to Mrs. Clean's Forum!
You have a large problem that can only be solved by getting the kitty fixed, but in the meantime we can try to help you out with the items already "damaged".
There are products available that claim to work on all three components of urine. One that was recommended highly was urine-off. One way to spot urine stains is with a black light. It will show all the places in the house that your kitty has marked. The makers of "urine-off" claim that after you use the product, it will not show up under black light, it will totally be gone! You can visit their website at
http://www.urineoff.com.
Another recommendation is Diaper pure.
If you would like more information on cat urine stain/odor removal, visit our web page for complete information at
