Oh, Tonya, I feel your pain. Butter is a quite a problem during the night, wanting to come in and out, and short of locking him in the garage (Scott's answer for the problem), I just deal with it. He bangs on the vertical blinds when he wants out, and climbs the screen on the slider when he wants in, and I wake up constantly! I would say it is a minimum of 3 times every night, if not more. I'm a poor sleeper, anyway, like you, but if we "lock him out", he bangs on our door and shreds the carpet outside the door. Usually, he can open the door on his own, anyway. Our only salvation is when Elizabeth, Scott's daughter, is here. He goes to bed with her and he can't open her door, and she doesn't hear him if he tries to wake her!!!! LOL!!! I sure wish Elizabeth was here more often.
