Feather has allergies. What? (I/we) Don’t know the allergen. It was the pronouncement of the vet. You might never find out and she will have a rash forever. So far, he has been correct. We have eliminated whatever. No luck! Cortisone ointment? No luck there. Oral steroids? Works like a charm, it eases the rash tremendously. Her hair has not grown back. I wish. Maybe the hair would insulate Feather from the allergen? I have settled on bi-weekly treatment. Ha! I can get steroids. Human drugs work on cats too. There are long term side effects. But the rash, untreated, is pretty ugly. You are looking at a good day – no hair, hardly a rash. My cat does not willingly pose with her rash. Would you show your worst side?
