This is my second door/window cat flap thingie. I like this one because it keeps the cold air out in the winter. I use this in a window leading to a porch. The cats use it summer and winter. I leave it in during the summer because the bunnies might come in the window, if left completely open in the summer....since the window is inside their pen. The cats love to visit with the bunnies all year long....I am not sure the bunnies feel the same way!

Anyway, I love this window insert.

Hope this helps.
