Dena asked some good questions.
Like she said, is she peeing and pooping outside the box? Can you tell if she is urinating in puddles or if she is spraying? Has anything changed in the last month, ie: new litter, new food, new litter box? My cat Snuggles was not happy when we got a litter robot that was hooded and that's where his behavioral urination began. He would pee on the carpet to let us know he didn't like that cover! If it is behavioral, there is something you can get called Feliway, it helps with stress and controlling urination outside the box, etc. My vet reccomended it, too.
I would definately have a vet check though, to rule out UTI's or any other health issue. There is medication to help if nothing else helps and if it is behavioral, but your vet would talk to you about that.
Also, what are you cleaning it with? Simple solution and Nature's Miracle are great because they have enzymes to get out the smell, also vinegar and water mixture works, too. Although I do know how hard to get smells out is, but make sure to clean it with something like that so your kitty doesn't smell it and go back to that spot.
Is there any straining or squatting when she is doing this? Those signs could indicate a UTI. Snuggles had a UTI 2 months ago, he was straining to pee around my house on the rugs and off to the ER vet we went. We caught a UTI right when it was starting.
I hope everything is ok with your kitty!
I see your from Orlando area. That's where I'm at, too.
