He was declawed about 4 mths ago so I doubt his messing is from being declawed. As far as his behavior, he's been like that since he was real young way before being declawed. My mom has been having him stay down in her basement. He has been staying down there for the past couple of months. My daughter stays at my mom's frequently and her bedroom is down there, my mom does her laundry down there and she lets him upstairs with her everyday for lengthy periods in the day. The reason/reasons she keeps him in the basement (mostly over night) is to keep him from jumping up on the kitchen table, sink, to keep him from running up and biting her or whoever and to keep him from getting into "things" in the house, (nick-nacks) etc. I told her I thought that it was kind of his way of rebelling because of being downstairs overnight but not sure why ALL OF A SUDDEN he's doing it.

As for something being wrong with him medically, that's a possibility for sure.

Thanks for the responses and if you have one about the basement, give me all the advice you have. I'm going to print off all the responses and take them to my mom to see what she decides to do.

Thanks a bunch everyone!
