My female moggy (16) has suddenly started weeing and pooing in DD1s room. DD1 doesn't seem to mind (!) but I certainly do, the place stinks.
We've had a visiting stray recently (who got the blame for the appearing turds) but although we've shut him out with a Sureflap the poos keep popping up. My feeling is she got stressed and maybe started marking and has just carried on now he's gone.
She's got a range of problems from arthritis to kidney failure and cataracts, I'm having the carpet cleaned this weekend and will put a stairgate on to stop her marking the same spot but is it worth a visit to the vet?
