For the pill - this is what I do with most of my cats. They all love shrimp, so I cut a half inch piece, put a small hole through the middle, and push 1/4 of the pill inside. Put these in the food dish - gone in a flash.

I don't know how many whole pills Starr gets in a day. Charley had to have 2 total recently, so I gave him just 2 pieces of shrimp with pill in middle at a time. I wanted to make sure he actually consumed each piece. Takes a bit more fussing, but it did work.

If not shrimp, maybe chicken?

Liquids can be messy, but even if it drips a bit about the mouth, he will lick it off eventually.
