We have 3 semi-feral cats outdoor and we have one of these doors into their indoor heated cat room which is also connected to our basement. They use it all the time and it works great. It has been on for 3 years and not much wear to it. It has a magnetic closure which sometimes the door will blow open if it is windy, so we put a dog box outside of it and they go in the dog box and then through the door into the room. This has helped alot especially if you install it on a windy side of the house. Would highly recommend any of the Staywell pet doors.

Pros: Lasts a long time, economical, easy to install

Cons: None

I use one of these on the door from my kitchen to the basement. The cats love it and I am not always opening the door for them. It can be locked both ways or one way only.

Pros: Better than a door man

Cons: none

We like this for our two cats because it works so well. Can't think of anything negative to say about it.

Pros: Well used

Cons: None

not a good idea my cat would get lost

Pros: not a good idea

Cons: not a good idea

Its not very insulated so you can feel a breeze sometimes... pretty durable though

Pros: easy access

Cons: lets cold in
