You have my sympathy. The first time we tried to put the cat's pills in food it worked, by the second time, she neatly ate all the treat and left only the pill. The third time, she would not come near the treat.
Crushing pills doesn't usually work with cats - they are too picky with what they eat. Friends who have tried it with dogs don't usually have too mcuh problem (the dog's desire for the treat usually wins over his distrust of the smell). Also, some pills are not supposed to be crushed (check with the vet before crushing).
What
did work (but was still agrevating) was a pillowcase and a pill dispensor
like this one. It's still not easy, but at least the pills
mostly got into our cat.
Here's what we did.
Prepare the pill dispensor acoording to the directions on the package (it basically has you put the pill in one part and when you push on the plunger, it shoots the pill into the cat's mouth).
You catch the cat and put her into the pillowcase with just her head sticking out. Fold the pillowcase around the cat so she doesn't have much room to move and also to make the open end of the bag small anough that she can't poke her paws thru. Your vet's office can show you how to do this. We got instructions on the phone from a friend who is a vet.
Open the cat's mouth - there is a secret way to do it that looks really easy in the vet's office. Once you get home, you can push in the same place and it is not quite so easy, but once you get the hang of it (like the last day the cat needs medication ), it does work.
Put the dispensor into the cat's mouth and push the plunger.
The first time we did it, it worked great (element of surprise goes a long way). Cats are very smart (and can produce enormous amounts of saliva on demand if they thing that will be a handy thing to do). Our cat found that large amounts of saliva were very helpful in ejecting pills after we thought they had been in long enough to swallow all of them. NOTE: Cats have good ability and aparently a lot of places in their mouths to hide pills.
Our cat also decided that large amounts of saliva would encourage us to not give her the pills at all, so she began salivating (really nasty) as soon as she saw the pill dispensor, pillowcase or pills. It helped to prepare those things "backstage" and then slip them out just when we needed them.
Also, we kept a roll of paper towels in the room we had chosen to give her pills.
Good luck.
