if i ever own a home all of my inside doors will have catflaps. i have a thing that keeps the door partway shut to let the beafts in and out but frankly i would really like to just be able to close it without ten pounds of god's perfect predator throwing a tantrum about it regardless of what side of the door they're on
can't shut them in bc the food/water/litter isn't in the bedroom, don't want to shut them out because then i won't get extremely necessary soft kitty time
