Yes, that's canned food we mixed his pills with. We use the different canned food since we didn't want Marlow to start hating his regular food.
Your other suggestions are very good ones that we had already tried. Another way of getting a cat to ingest the medicine is putting the food pill mixture on their fur. This worked for Marlow for about 3 months and then he stopped cleaning that area. That's why we started putting it directly in his mouth.
Hopefully your tip will help others who find giving pills to a cat difficult I put the other suggestions out there so others are aware of other ways to get a pill into a cat. Sometimes vet don't suggest compounding or Pill Pockets.
