What Causes Scabs on a Cat's Neck?

There are several reasons why a cat may scratch and cause scabs to form on its neck, including food allergies, rinworm and stress. Other reasons for scabs include tumors, fleas, ticks, dry skin and grooming products.

Scabs on a cat's neck can be diagnosed by a veterinarian in several different ways. These include scraping tests, tape tests, blood tests or a skin biopsy. Once the cause of the skin problem has been determined, a course of action for fixing the issue can be put into effect.

Topical treatments, a change of diet and antibiotics will clear up most skin problems. If the cat is suffering immensely, the veterinarian can administer an allergy shot to immediately relieve the itching and give time for the alternative treatment to take affect.
