Cat Door Latch, Adjustable Cat Door Stopper Dog Proof Cat Litter Box with Door Access from 1.1" to 5.5", Sturdy Pet Door Latch Holder Easy to Install and Use, No Ruin Paints, No Drill or Cut

I love this! My daughter sent this to me because I’m always complaining about the dog getting in to my room and eating the cats food but I didn’t want to keep climbing over a gate. I’m getting older and it’s getting harder on me to jump the gate lol No more! This is a life saver! Cat gets in, dog doesn’t and no more fighting a gate to get into my room. Easy in and out! Highly recommend!!

Works well to keep the door ajar just enough for my cat to come and go at night. It's rigid enough that the door won't shut while it's latched on

Looks just like the photo and it works without having to damage the door!
