the best way i know to pill a cat, is to put them on your lap or a table, and then scruff the back of their neck. not hard and do not pick them up. but just enough so you can tip their head back a little and their mouth will automatically come open. then drop the pill as far back into their mouth as you can, so they won't spit it back out. then just hold on to make sure they swallow it. it takes literally like 5 seconds and less tramatic IMO than wrapping in a towel.
