It seems to be a great fit. We'll see how well my chunky old man does with getting up and down the condo, but I'm hoping it will get easier with use. I was surprised he used the litter box cubby at the bottom, and the transition didn't mess him up.
I will be adopting another cat in a few months, so hopefully, one of them will get full use out of it.
One thing is that either the screws I was sent to attach the food bowls were the wrong screws, or the holes for them weren't drilled deep enough, so for now, I'm just using his current food bowl set up in the same spot on the included tray.
