Bart People: Lisa's cat form (snow leopard)

I just so happen to love the Treehouse of Horror comic Bart People.

This comic is about these cat people (were-big cats). Bart and Lisa are both infected with this curse and must study together or they will turn into big cats.

Throughout the entire comic the only one we see in their full cat form is Bart, and he is a panther. The end of the comic it is (possibly) implied by Marge that cat people are all panthers. I highly doubt all the cat people are panthers. That seems very unlikely. The feline family and humans are very diverse and that means the cat people would consist of different cats such as lion,tigers, leopards,lynxes,cheetahs,and many others.
It makes more sense if different people became different kinds of cats. Bart is the only one to have a confirmed cat form. We shouldn't judge just by Bart that all cat people are were-panthers. 

I think Lisa is NOT a panther. She is way too different from Bart the be the same kind of cat. 

Why I chose for her to be a snow leopard? Well, they are my favorite out of the big cats, they are beautiful, majestic, and strong creatures. I know that is a sorry excuse to make Lisa a snow leopard, but i am happy with my choice.

BTW: She still has control over her mind (she is no threat), but she cannot speak or act human.
