I have an older cat and he started peeing in my living room. I tried everyting I could find or make. Nothing worked. I was ashamed to have people come to my house because of the cat urine smell. I found My Pet Peed and tried it. Oh my god, the smell was gone gone gone. Later I scrubbed my carpets and expected the smell to come back. It never did. I love this stuff and recommended it to a friend who has 5 cats. She loves it as well. Thank you thank you thank you.
