Wow, that was a fantastic link. Thanks so much!! My male cat just recently started urine spraying and I'm trying to figure out why. He's been fixed for a long time and we've had him for about 7 years. We had a baby 15 months ago and that has changed things a lot around here. I don't hardly spend any time with my cat now. Plus my son now can chase him so maybe that's why. My husband just left a couple days ago on a long trip so he may be acting out about that too, although he did it when he was still here so I'm not sure. Plus I'm pretty sure he's used to that since we move a lot and come and go a couple times a year. What cleaning product do you recommend because all I used was some clorox wipes? Thanks again for your post. This helped me a lot; now I'm not so angry about it.
