I have a fixed male cat. About 2 years old. All night he meows and trills! He has food, water, box is clean. He's been played with and given affection all day....It's from as soon as the house goes to bed, til everyone gets up because he won't stop! My daughter is beyond tired because she can't sleep because of him. We've tried keeping him at one end of the house put away but then he yowls and that's beyond loud. I'm at wit's end. I've now been up since 4 because he just won't stop. We have two dogs so he's not alone. He has toys out. I'm at a loss!
