We have had a lovely rescue cat since November last year. He is about 3 years old. He had been a house cat with us because he had been in the animal shelter indoors the best part of a year and we wanted him to be settled at home before we let him out. Anyway, cat flap fitted yesterday and he's loved being out. He keeps popping back to check we are still here. Last night he came in at dusk and slept on our beds no problem and we locked the flap. However, tonight, he came in at dusk, we locked the flap and he has been scrabbling at the locked catflap and meowing to go out. What do you think? Just let him come and go all night? Perhaps he will settle and get used to being only out at night? Or perhaps he might not come back if he knows he's not going to be allowed out again? What to do for the best - I am overthinking, I know. Thanks for any advice.
