I've recently had a cat flap fitted so my cat can come and go during the days when I am at work. He loves it! It's a sureflap one and I've been locking it at night at 9pm so he can come back in but not leave again until I open it in the morning. The other day I was called into work during the day and expected to be home before too long so left it open but I didn't get back until 6 in the morning. Cat was out but came back when I rattled his treats only to go straight out again ( I needed some sleep so I let him!) Since then every night when I've locked the flap at night I can hear him bashing on it almost on the hour, every hour trying to get out, this can continue for 15 minutes and so far I've just been ignoring it. I always said I wouldn't let him go out all night but he just seems so desperate! The roads around me are extremely quiet at night but I know I will still worry about him and he has also got into fights/ been attacked by a local tom and this has only happened when he's been out late. Do I stick to my guns and just ignore all his attempts to get out and hope he settles or should I just let him go about his catty business as he wants despite the fact I will probably be worried sick (but maybe get a better nights sleep without the continuous noise )?
