Poor Nermal! Some cats do act aggressive when they don't feel well. You could try leaving her alone for the next few hours to see if she calms down and begins acting normal again once her stomach has settled. If there is no improvement in the next 24 hours, or if she continues to vomit through the day or develops any other symptoms, it would be best to take her to the vet for an exam. He/she can do some diagnostic testing if needed to help determine the problem and get her started on appropriate treatment.
