This may be late info but as an owner of MANY cats and dealing with meds on many here is my advice.
First no liquids--never works with a cat (IMO), be sure they give you a pill.
Options to try:
#1: Pill pockets, you can get them at any pet store. Sometimes a cat will eat them.Give them one without a pill first. IF that dosen't work"
#2: Learn to pill a cat. You might not be their friend but get them in a good position so you can pry their mouth open, get the pill as far back as possible, hold mouth shut, pet and stoke them until they swallow. Be sure they swallow. Try blowing in their face.
#3: If that is impossible you can by a pill popper. At local pet shops. Put pill in, insert it back in cats mouth (do the side, that why they can't use tongue to spit out) and "pop" it in.
It is trial and error with "pilling a cat", but once you have the talent (and I must admit I do) you can pill any cat!
