You can get Profender online BUT it does require a prescription. I'd imagine most vets would be able to get it though, because there simply are some cats that you just CANNOT pill. I have a few myself. I'm pretty experienced at pilling cats, but I have 3 that I would not even try with again. In fact one of them even the vet has said that no, she wouldn't try to pill either! You can do anything else, just not give pills.
I don't really like the pill guns because when I tried one (with one of my impossible cats that obviously struggled a lot) it tended to hit the back of the cat's throat and hurt him. For cats that are difficult but not impossible, I open the mouth, chuck the pill down and then push it with a cotton top as to have something soft to push with, but avoid my finger getting bitten.
