None of my cats "like" the hairball remedy... you just have to take a big glob and wipe it on the roof of his mouth ... or smear it on his nose or paws. If you put it on his paws, be sure you smear it in good, or he'll shake his paw and sling gooey goop all over the house!

Give it to him a couple of times a day for a few days... he should do ok!
yes, I know this to be true also, you just have to force it on them, as unpleasant as that is! I had that happen, I put some on one of the cats paws, and didin't do it right, and she shook her paw...hairball medicine everywhere!
good luckwith your cat, I hope he feels better.
