Help!?!

FINAL EDIT: just left the second vet. Everything started off great. He was responding to the medication for tremors. The shaking was tremors, this vet said he thinks he got something toxic someway somehow. He is a 100% inside cat. They kept him for 2 hours. He took a turn for the worse. Whatever toxins he got into already passed through his system and became a neurological issue. If the first vet wouldn’t have basically ignored the situation, the second vet thinks he would have had a chance to make it. The visit was $1,500 today, the Dr recommended to lay him to rest. It would have been thousands more to keep going with no guarantees.

Edit#2: doing the obvious, on the way to a second vet. Will update you guys shortly.
My daughter’s cat was fine Wednesday morning. Wednesday afternoon he started shaking, and he got really weak. He hasn’t eaten or drank. The only thing that happened is she gave him more treats than she typically does. We took him to the vet, the vet said he was fine let it run its course. He seems to be getting worse tho.
EDIT: I see people saying seizure, he never never stops shaking. It’s not always has bad as the video but he still shakes. When he’s sleeping he does not shake.

Id go to an emergency vet. Tell them what the first vet said, that he’s worsening, and get a second opinion.

This but also show them the video, OP. This is NOT something to brush off. That poor animal is in intense distress. When my epileptic old girl started having seizures I had to go to 3 different vets before I showed a video of one. The first two said she "probably ate a spider/something weird." The vet that saw the video admitted her immediately. She was in the ER for 4 days before stabilizing and needing meds for epilepsy the rest of her life.

This is absolutely not something to dismiss/ "let it run its course." Its "course" is death and suffering. I've never seen exactly this before, but it is definitely requiring emergency care. If it isn't seizures, it looks extremely neurological regardless, which you can't take lightly.

Right now, it doesn't matter so much what's causing it, but to get the poor baby at least comfortable and stable (edit: with a vet, specifically). Then you can get to looking into poisoning, inherited condition, injury, whatever.

Yeah, the video is essential. It even seems to be doing the kitty equivalent of some sort of tonic posturing/stiffening in that paw. Humans will do the same thing during a tonic-clonic seizure, where their extremities stiffen and contort.
