I provide dry all day for my 2 year olds to snack on, and give them one can of wet mixed with more dry in the evenings, the wet is usually gone by morning, leaving a bit of dry behind. They turn their noses up at the dry food alone for the most part, only coming back to it a little at a time as they get hungry. My cats are approximately the same size as raven and jack, and are both in good shape, active (for indoor cats!) and athletic, although they do both have a bit of that post-neutering paunch. This feeding schedule has been working out for me and they seem to be sated. They *gently* remind me (aka "dad. dad. dad. we're hungry. dad. dad.") every night that it's about time to crack out the can opener, but never seem to be wanting for food, nor do they seem to be overeating. Unlike dogs I've had in the past, my cats seem to know when enough is enough.
