Ok, I just moved into a new house and my cats were doing great. About 2 weeks ago I came home and they have peed on a blanket that was laying on the floor for the dogs..cleaned that up, everything was good. I came home last night and they have done the same thing to a blanket that was on the floor, but this time it went into my carpet. They are fine if nothing is left on the floor. Why would they do something liek this?
The first thing you should do is take them to the vet to rule out a UTI. Once they get the all-clear from the vet, you should read the "Inappropriate peeing" sticky.
