Hello,

As some have suggested, try Pill Pockets, a soft "treat" you put the
pill inside. Some cats gobble them right up, but others won't fall for
it. It's worth a try.

You can also bring them to the vet and have the vet show you how to
give a pill. Have him demonstrate with an empty capsule, then YOU try
in front of your vet.

Generally, I prefer to pill with the cat on the counter, so he/she is
higher up. I grab the head with one hand and tip it up so his nose
faces the ceiling. With the other hand, I use my pinky to pry the
mouth open (gently, there's a natural gap right behind the canine). I
stuff the pill in as far back as I can. Another trick that works for
me is to put the pill in slightly off center, so he can't immediately
spit it back up.

IMO, it's best to approach the situation calmly and matter-of-factly
and get it over as quickly as possible. Make sure to follow with a
treat or water.
