AngieFox, we have a doggie/kitty door that fits in the slider. It's as tall as the slider, and snaps right into the track. It's clear, so we can see out, except for the flipflop part at the bottom. Well, actually, now that I look at it, the flipflop part is clear, too. I have the litterbox outside on the lanai with a little table & tablecloth over it. (We could never find a convenient place in the villa for the litterbox) Baby Monroe loves his kitty door, and I love not getting up every 5 minutes to let him in or out.

Our neighbors have this style of doggie door from the house to the lanai, and they have another doggie door from the lanai to the grass outside so their doggies can run in and out whenever they want. We live in CYVs.
