I have two rescues, both fixed, both chipped and one of whom wears a tracker after getting himself locked in a neighbours house for a week last year and scaring the crap out of me.
Their schedule is out from early morning and then able to come and go till dusk when they are locked inside. Except twat face my boy cat is now waking me up at 2.30am onwards to demand to be let out. If its light, I've let him out (4.30am onwards and gone back to sleep) but last two nights I've waited until the sun comes up and had over an hour of claws, abuse and terrorist activity from him. And no, locking him out of the room isn't an option as he'll claw through the door and meow the house down keeping everyone awake.
Issue is we lost a cat a couple of years back during the early morning on a road when we lived in another village and so I'm a bit paranoid. AIBU to just say to hell with it and let the little sod out into the dark?
