To trick cats into taking pills, I use Easy Cheese (Kraft). I make a line of cheese, then a dot, then another line. The dot contains the pill. Cats eat the cheese quickly, and because there is a second line, they continue to eat very quickly and swallow the pill without noticing they consumed it. It doesn't work if the pill is just placed in a glob of cheese; the cat will spit the pill out. It's the line-dot-line technique that consistently works for my clients and me.
