I've been through the pill and liquid meds many times and I've learned that you need to be firm and give it to them as quickly as possible. If they squirm a lot then wrap them in a towel so they can't run away. When I give pills I use a pill syringe. I think this is the name of it but your vet should have them. It a plastic tube with a rubber end that holds the pill. This way the cat won't bite you by accident. Good luck. Just remember that practice makes perfect.
