Temptations for Hairballs treats are what I use.  The cats love them,
so there is no fighting about it.  They come in little foil packets and
are in the same location as the canned catfood is at the grocery or pet
store.

Also, my vet said, that using Laxatone on a continual basis really
isn't good.  It supposedly coats the stomach lining and prevents
nutrients from food being absorbed.  Are you feeding canned food?
Ample water intack is also important to avoid constipation.  And
combing or brushing long haired kitties also helps a lot.

Try Temptations!

Put it on his nose/mouth area. Just a little bit at a time, not the whole
glob. He will have to lick it off. I have never understood the paw
suggestion. What you will find is that he grows to like it the more he has,
if he is anything like my cat..
