Cats can have seasonal allergies too. Smudge has his "spring bald spot" in full view right now. But discontinuing an allergenic food (tuna) and an allergenic treat (cat lube) really took the edge off. I also give him 3V caps to help strengthen his skin, rub a little hydrocortisone in when he's sleepy and not really paying attention (if I only use a little bit and mash it on rhythmically, like a momma cat licking him, when he's tired & content, he won't lick it off immediately) and give him vitamin E as a treat just because it's safe and he likes it. He's a longhair, so I snip out mats, although it took him a while to get used to human groomin'. Now he just purrs.

Now if only he'd let me do his nails!

I can't change his base food (c/d kibble, prescription) because he needs it to keep from getting urinary crystals. But I changed his "treat food" that I mash his meds into (3V caps, chlorpheniramine, Cosequin, and psyllium fiber) to Newman's Own Organic, and that's helped a lot too. But some cats are just itchy and hypersensitive, and you might not be able to totally remove all the stimuli. Just keep trying. If she's really miserable, a steroid shot can give her a chance to heal up a bit, but it works by turning down the immune system, so if it makes her sneezy, be very careful.

It might be behavioral, too - stress can cause it. Definitely get a second opinion.
