How about getting one of those morter and pestles (you can get them in a kitchen store, they are used to crush up spices, they are made of marble), basically you just crush the pill to a powder form and then mix it in his food (this is how my Grandma gets my bed ridden Poppop to take his meds...he has trouble swallowing whole). Maybe that would work.

I had to give Gabe that stuff before i re homed him to SAS. and i use to stick it into the center of a hairball treatment pounce cat treat...they are kinda liquidy inside, and then give it to him...but who knows, that may not work...he might just end up spitting out the pill...
