It sounds like your cat is having a severe reaction to the antibiotic.
I would ask the vet if you can give your cat 1/2 of gravol to settle down the
vomiting.
What I would do to get more help is I would go the top contributors
in the pet section on Yahoo Answers & e mail them to see if they
can help. I have done this before when Im stuck on a computer question.
Wouldn't hurt to try. Good Luck with your cat.

Bring her to the vet. The vet knows best.
