My cat is 10 she sleeps all day and at a certain time at night she starts crying and running around and acts crazy. I get up from my sleep and I give her treats. But she still runs around like a crazy cat. She eats and does her poo and Pee so there is no problem with that. She keeps looking outside the window as if there is something there. I bought her toys but she does not play with them at all. I now keep a light on for her in the kitchen. Just don't no what to do. She is driving me and my husband crazy.
