The only way I've found to pill a cat is;
Supplies:
1. large fluffy towel
2. lots of band-aids.
3. a full bottle of scotch
Wrap cat in towel, hold on table with one arm and body, pry mouth open and pop pill in.
Retrieve pill from table. Repeat procedure until pill dissolves, spread pill in cats mouth.
Wash your blood off arms and fingers, apply band-aids and drink scotch.

You can use the same method to inject liquid meds in a cat mouth. Just have plenty of paper towels for the meds that are spit out.
