I agree with Deborah, it's very hard to see what's going on in that video. It does not look like poisoning to me, I'd expect twitching movements and head wobbles and not being able to move very well.
Not knowing what part of the body that is, it almost looks like a severe heart beat. I know people have talked about seeing that before.
I've used PAM since the early 2000s when I had a mite outbreak and ever since for treating QT. Spray cage and paper substrate, let it dry overnight. I usually put outside or near an open window.
I don't think that's what is causing the issue in the video, but it's really too hard to tell. I do agree 30 min was not enough time to let it dry out though.
OP, I hope your lil one is okay and the vet can tell you what is going on.
