I was also going to suggest having the meds turned into a transdermal gel. My cat Jimmy is on prednisilone and I've used that on him for a couple of years. As Jenn mentioned, you just squirt out the dose which usually isn't much and smear it on the inside of his ear. It enters his body that way and is so much easier. I use the back of a spoon to get it onto his ear.

You can also take the clomicalm to a compounding pharmacy and have them mix it up with a flavored suspension (chicken, salmon or beef) and then administer the suspension by syringe into his mouth or if you're able to, hide the now flavored meds into a similarly flavored food. But if your cat is anything like a few of my cats, they might be very suspicious of anything that could have 'tainted' their food.

That pill popper thing is pretty cheap, I think it's under 10.00 and most vet clinics sell them.
