My seven-year old cat has (up until a few months ago) been pretty mellow at night. He'd curl up on the sofa or the spare bedroom or in the bed and sleep until early morning (around 5:00 am)
Then, for no apparent reason, he started meowing really LOUDLY during the night (usually sometime between 12:30 and 3:00am). He calls so loudly that he can be downstairs and even with our bedroom door closed upstairs he will wake myself and my wife up.
He has food, water and a litterbox, so that's not the problem. The only thing I can figure out is he's lonely and wants to be with us, so I'll let him in the bedroom. That creates another set of problems. He's so restless! First he's on my side of the bed. Then he's between myself and my wife. He's off the bed. He's back on the bed. He scratches and his collar and tag rattles. He shakes his head and his collar and tag rattles.
My wife suggested we put him in the garage at night. I really don't want to do that, but on the other hand I'm like a zombie because I can't get an uninterrupted night of sleep. My wife even jokingly suggested some type of kitty tranqualizers.
Any suggestions would be much appreciated.
