"If you're calm, the cat may choose to be calm also"

If you can get the cat to be calm the first time, it's much easier subsequently - and for all other 'unpleasant' tasks you want the cat to do...

The trick to opening the jaw rapidly is key (do it right and the animal cannot resist and there is no pain or discomforr - it's a sort of reflex) - and if you can drop the tablet precisely past the tongue hump immediately after getting the jaw open, only the dignity is offended (the most important part of a cat!!!) and you can swoop her up, get the tablet in & have her automatically swallow, and put her back on the ground so rapidly that the act just gets tolerated - of course it will never admit to 'enjoying' that. It's totally a waste of time to even try the 'hide it it the food' game from my experience with both cats & dogs - the jaw trick works on dogs too.
