I learned with my elderly cat that while it was soooooooooo frustrating to push a pill to the back of her throat,
if I held her (normally--not cradling like a baby) and tipped her head up I could hold the pill in between my middle finger & thumb just inside her mouth, and pretty much drop the pill to the back of her throat where she'd have to swallow it.
Advantages to dropping the pill in instead of pushing the pill back:
1. Pushing the pill to the back of their throat stimulates their gag reflex. (Imagine someone fighting you to swallow something while triggering your gag reflex! Double-bind!)
2. If much saliva gets on the pill before it reaches its destination, the pill is very likely to stick somewhere on the cat's tongue rather than slide toward the back of the mouth.
3. When you are pushing a pill, the point of pressure from your finger(s) is right where the pill is, and the cat will resist it strongly with its tongue is likely to be able to push the pill off to the side. If you are dropping the pill, the cat isn't fighting with its tongue as much because there isn't as much pressure on the tongue, you have a better grip on the pill, and the pill is some distance away from the tongue so less likely to get shoved aside.
There you have it. My best advice. Made things a world easier for me.
