This could all be prevented if people were not too lazy to open & close their doors for their pets at need

My cat likes to come and go at 2 AM (yard is fenced, which discourages long forays). Not wanting to get up at 2AM is NOT "lazy".

My rat terrier dog is very shy, and will not make a noise to be let out. She just looks "worried". Doesn't work too well if you are in another room.

That flap is a wonderful addition to our home, and no coon, squirrel etc. has figured it out in four years of rural living.

We have a cat door for our kitties. We’ve had a few uninvited visitors. One was a racoon who kept coming in for chow until she got too big & fat. I heard a ruckus down where the door is & looked out to see a racoon with a cat-door girdle. She’d gotten stuck & ended up pulling the whole thing out. She got the girdle off & went away & we didn’t see her again until the next year. She came back with three kits & sent THEM in to get chow. Smart mama!
