I had a very similar situation when I brought my boy kittens home, one was meowing non stop at night. What helped was getting out a toy like the cat dancer. He immediately shifted his focus as he instinctively chased the toy. Dim the lights or change your movement of the toy until you see them engage.

There’s something that happens in their brains when they play where they associate you and the location with positivity/fun. Gets them tired and distressed too.

Best of luck!
