Pet door- who's got em" and your opinion?

We've used several of the less expensive Petsafe doors with no problem. I haven't lived anywhere more than 5 years so I can't speak of their durability. But they have worked well. I even put one (can't remember the brand) in a sliding glass door.

The best move we made! Once they learn to use them, you're good to go!

The only "visitor" we had was a baby opossum. It only took the dogs about 30 seconds to discover their visitor. I scooped it up in a box and took it outside. From then on we closed it at night.
