Hi Guys - I'm new to this site! I too have a problem with cat urine. I have three feline friends living with me and my Golden Retriever, Brandy and Yorkshire Terrier, Squirt. Aside from having cat unine on my carpets, recently I have one of my cats urinating on the furniture (couch in particular) in the Rec Room. Since I have three cats I don't know which is the guilty party!!! It is not a litter box problem as the boxes are cleaned at least 3 times a day. None appear sick, no change in home life so I am baffled why this is happening. Any suggestions - all will be welcome! Thanks, Syl
