Asking for advice. Got a beautiful little 1year old rescue cat a few weeks ago. He's settled in beautifully after a nervous start. He loves being outside (desperate to get out) but always comes in to use the litter tray. I've tried sprinkling his used litter outside and also putting earth on the litter tray inside to no avail!
For background, he was found in a shed by builders and taken to the rescue shelter where we eventually got him from.
Any advice gratefully received.
