from Evelyn

My cats hate it and refuse to go in.

from JT

My cats won't even fit through the sides. Returning.

from Working Mom

It was bigger than I expected so I had to move it down the window some,the cats haven't gotten into it on their own,but it's a new to them, so I'll give them time

from Jenny the Fashionista

Make sure that you measure. I didn't and most of my windows are too small. Also, it will be great once the summer sun arrives. Not too toasty next to the glass in the snowy winter:)

from AmoebaTheCat

This is a good idea, but I'm not convinced it was developed with sufficient market research. I have a few cats, all of different sizes. None of the adults, large or small, fit into it comfortably enough to turn around, so none will go in it. If you have kittens or TINY adult cats, maybe.
