From the way you describe it, I too would be very surprised if this weren't caused by a medical problem. Even a mild urinary tract infection or a few crystals in the urine can cause pain and lead to litterbox aversion. The sooner your vet checks this out, the better.



Whether the problem was caused by an underlying medical condition or not, one thing to keep in mind is that the floor area must be THOROUGHLY cleaned. If there's a faint smell of urine on the floor, that will trigger the cats to urinate in that spot. Cats have a much keener sense of smell than we do. It's possible you have cleaned the area well enough so that no human could detect any residual urine, but a cat could still smell it. Just to be on the safe side, I recommend cleaning the floor with an enzymatic cat urine cleaner. You can buy these products at most pet stores. A bottle only costs a few dollars.



Best of luck to you and both kitties. Let us know what the vet finds.
