Couple things you can try.
Try mixing it up so that it's basically a power, and mix it REALLY well in a bunch of stinky smelly wet food (if your cat likes it). Or try putting it in a LITTLE amount of human tuna, or cat tuna. Mix it so that the cat can not see any of the pill.
Also, have you tried taking the pill and rolling it up inside a peice of cheese so that it's completely covered? I use this with dogs sometimes and it works great, they just gulp it right down.
Other then that, have you tried just placing it in your cats mouth and having them swallow it? If you trust your cat not to bite you that is. And yes there is always a pill gun you can use (get it from a vet, they can show you how to use it.) But even those aren't totally fool proof, my Asim has shown me that.
