    This photo shows just how bad Asia's hair loss (alopecia) got over the winter. She lost virtually all the hair on the lower half of her body. Though it is faint here, she also has some red patches on her skin. Her condition improved a bit in the spring, growing some of her hair back.

    Asia's supposed histiocytoma is shown in this photo. About three weeks after it appeared, it started to clear-up. It was a relief to see it shrink away, as a surgical removal became unnecessary.

    This photo shows the rash that Simba would typically develop when his skin problems flared up. You might also notice that one of his nipples is enlarged from being chronically irritated as that is an area where he scratches a lot. The sores became much worse over the summer of this same year.

    This photo is from later in the summer. Notice all of the freckles you can now see on his skin, which was not visible before his hair loss. Though it is hard to see from a photo, he has very little hair anywhere below the top of his shoulder blade.
