how do i get my overgrown hellcat to be a regular hellcat again? it was a regular hellcat then i left it in the bank for a while and it became an over grown hellcat. do i shoo it away and get a new kitten or can i do something to get it regular again?

I dont think you can reverse it. My advise would just to get a new cat.

Once it's overgrown it can only become a lazy or wily cat if you've completed rat catchers. Any cat will eventually grow into an overgrown (it's the end stage of their growth), they don't stay regular cats.
