We have a ten year-old male who has taken to toileting indoors. It's always been an occasional thing, he seems to hate getting wet so rainy days were always an issue, but it's become a regular, pretty much nightly thing.
We have a cat flap and a big garden so it's not that. He won't use a litter tray. We've been using puppy pads which is sometimes successful, sometimes not.
Has anyone got any ideas that might help? It's driving us crazy.
