I have a car who wants to be outside on a regular basis. Sometimes you take him out on a leash or use a yard stake setup. The cattery is a great option for longer periods outdoors. I’ve seen him go in the cattery to look around and sit on his benches even when he is leashed and able to walk around. 
The cattery was easy to setup. It’s not too big or too small and the natural wood look is attractive / doesn’t dominate the whole yard’s aesthetics, which was a big selling point for me. 
The only complaint is the lock rusted within a few months, but it still works and can be replaced.
