It's for large dogs

I have 5 cats and they like to come in and out so this was a great idea for me to install the doggie door and it was quite easy to install the only problem i had was that you need to apply adhesive to the corners or edging of the door for it to stay secure and in its place let dry well before rehanging your screen door

So it's great

This product is awesome very well constructed not flimsy at all can't wait to put in my screen door
