This would be a great idea for feral cat colonies. In the winter time these could go on the doors of the little insulated dog houses.

Pros: great cat door

Cons: none

I would like to try this on my door to my enclosed porch. My cats don't go outside, but they do like to be out on the screened porch sometimes.

Pros: lets kitty have freedom

Cons: none

These are great to have around. My moms friend has a feral cat colonyt and she uses one of these and it works amazingly. :-D

Pros: great to have

Cons: none

My cat stays indoors. So if I used this it would be on an inside door to another room.

Pros: easy to use

Cons: don't want cat outside

This is a great idea cats love to come and go as they please.

Pros: Cats can come and go

Cons: Door has to be open to use
