There was only sugar in the candy cane.
Ever since she sneaked a pack of sugarless gum out of my purse and ended up at Auburn University Vet school, I worry every time she climbs on the counter and gets some human food. She's a stray and a scavenger and very canny. She can smell sugar or sugar substitute through any material. The vet at Auburn said that she would never change. We try to be very careful but she's smarter than we are.
Thank you very much for your answer.
