Put the pill, in small bits or ground up, inside a bit of raw ground meat - that's worked for any cat I've had to pill - I could never manage to do the jawpinch maneuvre right.

The dog was easy. You take three chunks of hot dog. Slit one, place pill inside. Throw one piece to dog. Throw piece with pill in next. Make sure dog knows you have another bit in your hand. Dog will down pill without bothering to taste it... especially if the cat is nearby and might get that third bit!
