My Kata sleeps in his crate inside my room during the night and play outside/sleep (in a floor tile) beside it is his potty spot (cemented floor) and I'm worried what if I let him play in our living room. I'm afraid that there will be an accident
Before you let him in the living room make sure he goes out for a wee, then 10 minutes later take him out for a wee again and repeat. If he does have an accident clean it up with simple solution or similar as will get rid of the smell. He may have the odd accident but will learn quickly. I would give it a go. Good luck
