Not to just say"ditto"
,but I too have always fed my cats(3 neutered males) canned food twice a day and dry 24/7,all 3 of my cats drink a lot of water.
Through trial and error,I have narrowed the dry food down to 2 kinds that they like,Nutro Complete and CSFPLS(chicken-soup-for-cat-lovers-soul),reasonably priced and good ingredients.
As for the canned,I tried everything,but they refuse anything other than Fancy Feast
