I think these are great for home and at the shelter. Easy to install and nice for the cats and dogs.

Pros: training puppies, easy access

Cons: none

This is so wonderful (for the right dog).
My shorehouse has this doggie door and it gives my dog the option to out whenever he needs, while we are sitting at the beach all day.
It's pretty good about not letting the air-conditioned air out also.
thanks!

Pros: doggie doors are great!

Cons: none

I have friends that use this door for the cats to get to their basement litter boxes - a great invention!

I don't like a door that let's pets go outside without supervision. I also heard how the raccoons come in at night through this door - help themselves to left out food!!!!

Pros: Great for access to basement litter boxes

Cons: Not so great to let pets outside without supervision

my daughter has this in her lanai door that leads to the patio ...her dogs can come in and out without her having to be at their beck and call...it is cost effecient sturdy easy to install and it looks nice also as it blends into the style of the door it is very durable

Pros: many

Cons: uninvited guest might show up

This is noisy when the door opens and closes. My cats are afraid to use it. But my dogs will go in and out of it.

Pros: my dogs use it

Cons: my cats won't use it, noisy
