My previously well trained 18 month old cat has started peeing outside the litter tray. She has so far peed on all the beds, her bed and now one of the sofa cushions.
She’s been to the vet twice and had antibiotics, a probiotic and metacam. We have a feliway plug in. I’ve changed her litter box to a bigger one and now i am at the end of my tether.
Any suggestions?
