We have a 15 year old cat who has entirely stopped going out to poo. We have a litter tray which is cleaned regularly but the cat poos three or four times a day on the doormat right next to the litter tray - really vile liquid poos. He sometimes does it in the tray too.
I'm at the end of my tether. The vet said last time we took him that there's nothing essentially wrong and offered us anti-inflammatories. I am having thoughts about having him put down because I can't bear the poo any more. And we are going on holiday tomorrow and the thought of someone else having to clean up the mess is unbearable...
