I have a cat that will go bald from scratching every year. The vet gave her a cortizone shot and the symptoms disappeared until the next year. She has seasonal allergies. Her symptoms are weight loss, scratching, bald spots, and vomiting (hairballs).
She had to have surgery a couple of years ago and the vet told me to give her Benadryl liquid to keep her groggy while she recovered. That year I noticed the allergy symptoms were gone. The Benadryl worked wonders! I don't remember the dosage but your vet or local animal hospital may be able to tell you. It is very easy to administer liquid meds with a dropper.
