Thank you so much!!
I called her vet and he asked me how much (I only saw the tip of one a little chewed off) and he also asked me how long ago (at that time it had been 6 hours) and he asked me if she was acting odd. I told him no. She is still eating and playing fine. He said since it was such a small amount that she should be fine but if she starts to act odd please call him and he will see her.
You might get some bitter apple or something else your cat dislike to smear on the leaves of the plant to discourage her. Honestly, Aloe tastes terrible, so if she got to the meat of the plant, she may be discouraged enough already.
