I'd totally have a vet check done. For the last year, year and a half, we had Mimi (we lost her at 15) we cleaned up messes several times a day. There were days I'd get home and just cry because she'd gone to the bathroom and then tracked it all over. We had the hospital bed pads down, so it stayed on those, but I got really tired of doing laundry. She never would have gone to the bathroom in the house when she was younger, but she just couldn't help it.
I'd give anything to be cleaning up messes and doing laundry again.
