The clomicalm (at least the generic version) tastes REALLY REALLY bad!!! I doubt any cat with taste buds would eat it out of a dish, even mixed with tuna!

Wrapping is a towel is a good idea! Beware, though ,they may run away when they see the towel coming, in the future.

Scruffing is also a GREAT way to pill a cat. And so is having help.

I like to turn the cat on its back and lay it across my lap so when the mouth opens, gravity works with me and not against me. Just pop the pill!

But most of all, just keep trying. Once you get a technique that works, the cat will relax more and more with time.
