I just went through this with my one cat Oscar. First I put a little bit of hot water into the food bowl and drop the pill into it. Then I open a can of salmon and drain the juice out of it into the bowl. I crush up the pill with a spoon, making sure none stays stuck on the bottom of the spoon.

Oscar laps it up and all is well.

Good luck!

Edited to add - I'll be having a lot of salmon salad for a few days!
