hmm, it seems like they only have oral flea stuff? which used to be fine, but the last time I tried pilling my cat it was Literally Impossible, idk what changed :<

I'm pretty sure that there is a somewhere a method to train your cat to eat pills. Like at first, click with your clicker and if the cat comes nearer, feed them a treat. Do that for sometime, then train them to open their mouth etc. etc.

There's a lot of tutorials on dogs about stuff like this.

hm, I did just start clicker training her, maybe I can figure out how to apply it to pilling

the thing is though, getting the pill into her mouth isn't that hard; she will literally never scratch or bite me, ever ever ever ( ilove her so so so much ;_;) but she seems to have gotten better at spitting the pill back out/keeping it from going down her throat

Look up shaping. Here's a simple video, but as its been studied by psychologists there tons of information about shaping.

You could try to teach her to swallow on cue if a pill is present, but I have no idea how'd you make safe practice pills.
