My senior dog has some potty problems lately and has peed on the carpet some. The thing that is really weird though, is that my cat keeps going to the pee spots (before I can get the carpet cleaner ready to go and clean it up) and laying down right on it!!! Why would he want to lay on her pee spot?? One day, he was actually rolling on the spot too. I just don't understand...I had to shoo him off it twice just now.
