Cat people: I need some help regarding Cat 2 before I turn him into a rug.
Put simply: he's a nightmare overnight. He's always been this way, so it isn't a new thing and therefore I'm not worried about getting him medically checked out. The nub of the problem is he will not let me get a night's sleep. If I shut him out of the bedroom - which I must do, so I can sleep with the window open - he will meow constantly outside the door, scratch up the carpet and make noise all night until I let him in, which I eventually have to do or I don't get *any* sleep. (Even when I don't let him in and 'reinforce' the behaviour, it makes very little difference - he goes right back to doing it).
He's not hungry or thirsty: he has biscuits and water available 24/7. He's not wanting to go out (he has a catflap, so can come and go as he pleases). If he can't be bothered to go out he has access to his litter tray, so I don't think it's a 'need'. He's not shut in anywhere; he has total access to the rest of the flat. He just doesn't want to be shut out of the bedroom. The old suggestion of playing with him for a while before bed makes no difference, since he's not really a 'play' type cat (they've always been indoor/outdoor, so made their own amusement; toys are a bit of a mystery to them).
If I do let him in, he'll sometimes let me sleep, but other times will wake me up for fuss half way through the night (which he doesn't get, so I'm not reinforcing it that way).
I think he just wants me to be awake *with* him.
My preference is to shut the door and not have him (or the other cat) in the bedroom so I can have the window open overnight.
