Health & WellbeingOverweight cat with dry, scabby skin and worms: OTC solutions?
This is probably due to a severe allergy, although it could also be fleas or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage) and worming treatment. Ideally you should get her to the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try discovering the cause of the allergy. Some medications can be given in order to stop the chewing and repair the skin lesions (steroids and antibiotics). Some shampoos can be used to improve skin quality and allow normal hydration (EPI-SOOTHE shampoo). There is also a nice topical spray available, it's called Cortavance. Hopefully you will see some results after all this, if not you and your vet should consider starting on a long term allergy treatment.
