how exciting , good luck.
Raw meat (eg Jimbos/max) , raw chicken necks (chopped into thirds for littlies), quality dry food to graze on (eg nutrience, Royal canin) and an occasional tin of dine (the small tin, not dome . pure seafood no additives) is what I feed my cats on.
As Jennifer said, aim to have some moist food in their diet. Raw meat alone won't meet all their needs, but dry food alone isn't always the best either . so variety!
Raw meat and chicken necks is ideal for keeping their dental health in order becuase they have to really chew. Most of the dry foods just shatter in their mouth and do little for dental health. But with the premium dry foods you know they are getting all the nutrients they need and the convenience of grazing which cats prefer.
My cats get wet once a day and a bowl of dry to graze on.
