Review on Door Buddy Adjustable Door Latch (Grey 2 Pack) - The Ultimate Solution to Dog-Proofing Your Litter Box! No Pet Gates or Cat Doors Needed. Easy and Convenient Cat and Adult Entry. Put an End to Dogs Eating Cat Poop Now! by Sally Bienz

The first one I used for the bedroom door so the cat could get in but not the dog or Roomba. Works like a charm and withstands a dog pushing against a door. The second I used on the dryer door. We have a tiered washer-dryer and the old dryer door often slammed halfway as I bent down to pick up the laundry and poked the back of my head. I used one of these to give myself a way to secure the door. I never had to swear at the dryer with a random curse again. The stickiness of these things is AMAZING. Our landlord turned off the dryer when the old one broke down. The new one doesn't try to kill me and I couldn't get the other half of the bolt back so I tried to get it off its mount. I gnawed at the varnished wood and plastic with a flathead screwdriver, trying to pry it off, but gave up. I'll try the razor blade sometime I think.
