As the pictures show the patio mount sits against any outside wall. If you have more than two cats I suggest purchasing the patio model because of its size.

This model will hold a very large litter box and still gives your cats enough room to sit and look out the windows

As with all my Kitty Kat Casa's if needed, for an additional charge I can custom build a special casa to fit your special needs.

You will need to have a cat door cut through an existing outside wall to allow the cats to pass from the house into the Casa.
