Stinkie has always had a curfew. He has to be in by a certain time every night and not allowed to go back outside until morning. That's not usually a problem. He's been doing that all his life. He's never been outside at night. And usually he sleeps through the night. But lately, over the past couple weeks, he has started getting up and wanting out during the night. He's clawing on the blinds, scratching at the door, meowing, etc. And yes, in case you're gonna ask, he was neutered when he was a kitten. But the question is, how do I get him to go back to sleeping through the night?
