About a year ago, all my cats went to stay with my mother while I was out of town. My mother has four cats
of her own, and has kept all the cats in
the past. She does, however, have a cat diagnosed with "flea allergies" that is prone to scab outbreaks and irritation. She has to take him for cortisone injections frequently and keeps topical flea meds on the cat. After returning home, my youngest cat (Phoebe, 4 years old) began showing the same symptoms.
