I moved to a new apartment on May 1st and my cat (only have one) has taken to meowing at 4 or 5 am in the last week or so. Am I doing something wrong? He has never done this before. In my old apartment, he slept with me in a closed bedroom. He has been spayed and has ready access to food and water at all times. I give him dry food every day and half a package of wet food on Wednesday and Sunday mornings. My new apartment is a studio but, like I said, he has only started this in the last week or so. I have tried ignoring him but I am worried he may irritate my neighbours because he does it in the hallway by the door (he has never been outdoors). Any suggestions?
