change in behavior

My 3 year old cat has recently been sleeping a lot more, not coming when called, has dry nose, will sit, stare off into space & rock, meowing a lot more than usual & seems to have lost his balance. He is eating  & drinking & hasn't lost any weight but I am very worried about him. Seems like he has lost his mind a little.
