This is my tuxedo cat, Fiona. She is five years old. Unfortunately, Fiona hasn't been doing well. She has been very itchy lately and a lot of her fur has been falling out. Some parts of her skin are red and she is constantly scratching it. Moreover, her paws are very irritated, inflamed, swollen and red. Fiona's vet believes some of her symptoms have to do with her immune system.

Based off what we have learned during this unit, discuss with your group would could be wrong with Fiona. Use your prior knowledge from this class, as well as your own pets to help diagnose her.
