"I have four cats — all of whom were strays. We 'rescued' all four at different times and, so with all but the first cat, we went through a phase of bitterness and hatred where they urinated on everything in sight because they were so (if you'll excuse the pun) p*ssed off. One is still relatively new and so, right now, my bathroom smells like the shared bathroom at an all-boys dorm at a university for students who are aiming-impaired. My second cat (Guacamole) is very timid around people and he is particularly mad at me for some reason; so, Waka peed all over the sofa, all over my clothes, everything.
I sprayed this stuff on my sofa, but I read the reviews before I did and I thought to myself, 'They say to saturate...' so every time I walked past my sofa for the next two days, I sprayed the crap out of it with this stuff. I didn't go back and stick my nose in the couch for about a week (because really, who wants to shove their face in cat urine). Finally, when I was sure it had dried and all the little enzymes and invisible magic gnomes in this stuff had the opportunity to work, I went back and took a whiff. I lowered my elevation sufficiently from 3 feet above couch level to where I thought to myself, surely, no person will ever come any closer to the sofa than this (about a pillow away), and I could smell nothing. My husband has sat on the couch and neither of us smell anything. The cats have sat on the couch and, whether they smell anything or not, I'm uncertain (they don't talk... you know... they're cats), but they haven't started peeing on the sofa or made it obvious that there is a funky aroma there.
I'm buying more, and you should too. Yeah, it might cost less to buy that miracle stuff or some sort of carpet cleaner, or captain Joe's spray and go, but this stuff actually works. How much money are you going to waste trying to save money before you finally decide to put your wallet where your cat's urine is?" —Brian
