My cats have access to my custom blend of premium dry food daily. However, in order to maintain the urinary tract health of male cats it is imperative that they get enough fluids in their diets. Since canned food contains lots of water, I make sure my boys get a helping once a day, just in case they aren't drinking enough water. Simply a preventative measure so they won't suffer any urinary blockages (which can be mistaken for constipation), and is a MEDICAL EMERGENCY if the cat is a male. I like to be on the safe side when it comes to my "children".

Through trial and error, my boys won't eat any canned food that is sliced or has hunks in it, so I give them the ground type, i.e. Fancy Feast Gourmet. Many other companys also make canned ground food varieties. My brat, Chaz, will only eat Natural Choice Chicken & Rice. I spent a pretty penny or two trying every canned food in order to tempt him. He gets a dollop once a day.

So, if you haven't already, you may want to try the ground type of canned food to entice him, unless you notice that your boy IS drinking plenty of fluids. If so, trying to get him to ingest canned food is probably unnecessary for his health . . . besides being tough on your wallet.
