Hi All, we’ve had our kittens since July. They are now 6 months old, neutered and chipped. We installed a cat flap, which they are using well. We still have the litter tray inside, as for now we decided to keep them in overnight. Despite this, they poop on my artificial grass. I don’t know how to stop this. Should I move their litter tray outside? (Photo attached as per rules 😉)
