I would fill a dropper with alittle bit of water.
i would kneel on the floor pull the cat back in between my legs.
the back of his head close to my stomach

tilt his head back open his jaw from his top teeth
drop the pill all the way at the back of his throat.
DO NOT LET HIM MOVE HIS HEAD TO THE LEFT OR RIGHT!
then squirt the water from the dropper in his mouth which will force him to swallow.
keep his head back of a minute scratching his neck to make sure the pill went down.

(MY BOY WOULD GIVE A QUICK SHAKE of HIS HEAD AND THE PILL WOULD GO TO THE SIDE THEN HE WOULD SPIT IT OUT)

It takes a little practice
