Cat Mate Electromagnetic Cat Door for Large Cats
Sturdy door works great. The first one broke after about 8 years of use. Purchased the same model. Doesn't keep the raccoons out, but it does keep the neighborhood cats and strays out who like to spray in our garage. I have only had one cat that was smart enough to get past this door.
