The easiest way I've found to pill a cat:
Sit the cat on the floor in the kitchen facing the cupboards, pills at the ready on the counter above, crouch behind him w/your legs on either side to block escape. One hand holding the head still, pill between the thumb & forefinger of the other hand, use your ring or middle finger, of the pill hand, to pry open the mouth. With forefinger on the pill place it on the roof of the mouth & quickly slide it all the way down the back of the throat. This way there is no chance for them to spit it out, and it's over much faster. Treat afterwards.
Avoid biting when a simple growl will do
