This catio goes together quickly and easily. We put it on our deck outside the window so we could watch them. We tried it out with all 3 of our cats, one at a time. We have one who enjoys hunting critters too much, so we were hopping we could use it more for her. She has been in it a few times, and as much as she tried, she could not get out. Our very old cat tried it out and actually loved it because she never goes outside anymore and this gave her a safe way to lay in the sun and smell the outdoors. Our 3rd cat spent about 10 seconds in it and wasn't too happy. But that's fine as she isn't a problem and doesn't need to use it. We found that giving them treats/food in there and their usual bed makes them feel comfortable.
