Randi - this is the strategy I use with Spence.
I take Spence by the back of the neck (this creates sort of a paralizing effect, like when the Momma kitty carries her kittens)
Spence relaxes and I'm able to open his month - drop the pill in, let go and massage his throat to cause him to swallow. Works all the time - however once in a while, not often, he'll kick with his back feet - gotta watch that, he's scratched me quite deep a couple times.
