What chance does cat have after being poisoned with anti freeze?

I don't think so, it's a horrible thing for a cat to go through. My neighbor brought over a cat she found, and I began freaking out. Having seizers and foaming at the mouth. It was so horrible to see, not only is it horrible to see it's so PAINFUL for the animal that took it. The cat died. It just sucked really bad, I don't think there's anything you can do. But atleast the vets are trying to help
