I'm sorry to hear that Gofret is having so much trouble! There are a number of things that can cause itching similar to what you describe - it's true that allergies are one of the most common causes, but he could also have a bacterial or fungal skin infection, parasites like fleas, or even skin mites (mange). Your vet should test for these things if this hasn't been done already. If skin tests for all of these problems are negative, then it's likely that your cat has an environmental allergy of some kind since the hypoallergenic diet has not helped. In that case, you will probably need to use a long-term medication to control his symptoms such as prednisone, Atopica, or Apoquel. It may also be an option to have allergy testing done so that you can do hyposensitization injections if you wish - you can ask your vet for referral to a veterinary dermatologist, or get a second opinion from another veterinarian in the area if needed.

    Allergies can be very frustrating to diagnose since there are so many causes. Hypoallergenic diets can be great in managing but if the diet contains an allergen that causes a reaction in Gofret, it won't be much help. Consider allergy testing with a veterinary dermatologist to determine exactly what foods or environmental factors trigger his allergies. In the meantime, consider nail covers such as SoftPaws to prevent injury from excessive scratching. An e-collar (cone) may also be necessary to prevent licking and chewing. An essential fatty acid supplement may provide relief. EFAs promote healthy skin and coat and are said to have natural anti inflammatory properties. Discuss antihistamine use and hydrolyzed diets with your veterinarian.
