He usually stays in at night. But has had a strict curfew in place only for several months between 7 and 6. (Both ish times. Generally close enough though)
He's taken to this new situation ok, in the evening he might mew by his cat flap a bit but it doesn't last long at all. He then just goes off to sleep somewhere (changes location during the night). He's a very laid back and calm cat.
Got woken at 2 last night by DH, he'd be out and had been in around an hour and was concerned about Cat's behaviour.
Cat was dashing all over the house, scratching frantically at his usual scratching spots, jumping on the bed at me, on the window ledges, miaowing loudly at front and back door. Miaowing at dh.
Anyway DH woke me up (Cat is mine, DH isn't a cat person) at that point Cat was at our bedroom windows going at the latch. I got up and Cat jumped ran down stairs, then back up I followed him and he was straight to his cat flap circling.
I was quite hesitant but let him out; his behaviour reminded me of a dog I once lived with when this dog had diarrhoea and was desperate to go out (Cat is a litter box refuser). Watched Cat outside he did his usual recce then went up the wall and and off along all the other garden boundaries at a right speed and not to were he might for toileting.
