Having never sailed a cat prior and now, just having returned from delivering a Lagoon 37 I'll mention my thoughts, such as they are.
A different motion for sure. Not bad but like a piece of plywood floating on the ocean.
Coffee cups, bottles of wine, et.al. stayed where put on counters except in rough weather.
Plenty of room to lounge about inside and out along with good storage.
It didn't point as well and did take a bit to tack. We did well although our sails were quite old and stretched.
Bottom line, we're I looking for a liveaboard I'd now definitly include cats in my search.
