I'm new here and thought I could pick your brains on cat flaps.
I'd like to get a cat flap put in our door so that the cats can come and go without me having the door open all the time one of us is at home (like we have done for the past 10 years). It would be quite nice to heat indoors rather than the great outdoors
2 problems though. a) It's a uPVC door and I'm not sure how easy or otherwise it is to fit a cat flap to one of them? and b) I don't like them going out at night, but one insists on going out at stupid o'clock (any time between 1 and 3) in the morning so I have to crawl out of bed, find my way downstairs and let him out. I'd prefer him to be in between 7pm and 2am or so, at least, really. Is it possible to get a cat flap with a time release on it so it stays locked between specific times? It would also be locked while we're both at work, so really would only be used for early mornings and an hour in the evening.
I'm beginning to talk myself out of this idea - maybe it's easier just to leave the door open
