Any rx for cat's "pms"?

Tweet

Ever since I got Mimi, I treated her as gently as possible. When she jumped on my lap, I pet and talked to her. She wasn't sitting on my lap for a half a minute before she began to growl and suddenly bit me. This wasn't the first time that she's done that. It was like she had PMS. She still jumps on my lap, though, and a few seconds later, turns vicious and bites me. Mimi still chases Waffles, the other calico cat. She doesn't play, just sits in the sunporch most of the time. Her previous owners had her declawed (front paws)and owned her for five years before reluctantly giving her up due to their son's allergy to cats. When I took Mimi to the vet last July, the cat was just as hostile, and the vet had to call for some assistance. So far, I've had Mimi for ten months, and am just wondering if there is any hope for her changing her ways and any possible remedy for her pms.
