Remarkable how much you've accomplished, Jama.
I'd not have a suggestion except this one: the "whole cat" has yet to be addressed with constitutional prescribing, hence the seizures are still present. If the sulphur you speak of is in potency, I'd stop it and get a professional homeopath to help you find the simillimum. Staying too long on a "close" remedy can do damage.
All the best to you and her.
p.s. it was malpractice to vaccinate for rabies, law or no law. This cat was sick at the time, and that's counter to every rabies vaccine's label: "Only for Use in Healthy Dogs, Cats, Ferrets, etc."
