So not long I noticed that my youngest, Vivi, had a little patch of fur missing on her belly and what looked like a scab (upon initial inspection). I'd started her on a new food a couple of months before, a food that didn't seem to be agreeing with her (scratching, dandruff, not feeling as perky and playful), so I assumed it was a scab from gnawing on a belly in gastric distress. I kept checking on it and it lightened in color, went from reddish pink to light tan, and I thought that was kind of peculiar, but an improvement, so I continued keeping an eye on it. Then a second, smaller "scab" appeared next to the first and all of a sudden they're both that reddish pink! The answer to your question is, Yes, I did switch her to a different food and she is doing much better. A little scritching, coat looks good, behavior is normal. And now the "scabs" have shrunk a bit in size. And it just occurred to me, I can't believe it took this long, that this odd patch of skin reminds me of the eczema I get every winter on my arms. It can get pretty scaly and red, then turn light tan, then flare up again and darken in color. Am I on to something here? And if she's doing so much better on the new food, do you think this skin thing will heal on its own, or should we be making a vet appointment? She's happy and healthy otherwise.
