My primary and overwhelming thought is "feature creep". Try first to get a working prototype that measures the amount of water in the bowl. Then worry about weighing the solid food, multiple bowls, weighing the cat, multiple cats, connecting the CCTV to power and network, automated cat identification, setting up OpenCV, doing a ML, and the User Interface.
