I'm sorry to hear that you're having so much trouble pilling your cat. When my RB Pepper was very ill, my vet did give me several syringes with antibiotics in them so that I could give him these at home. Ask your vet about something like this.

Have you ever tried giving him liquid medicine. Most meds can now be compounded into liquid form and they can also add a flavor to them to help them taste better. You may also want to buy a cat sack or a klaw kontrol bag. I have these and once you put the cat in them, they can't run away from you. Here's a link to them: http://www.fourflags.com/s.nl/sc.2/category.3950/.f and http://www.drsfostersmith.com/produc...fm?pcatid=3159. Good luck.
