Of course, getting to the cause of the itch is crucial, because any topical treatment is only going to mask the symptoms (and, holistically speaking, drive the disease deeper). Allergies (especially flea bite allergies, atopy (inhalant allergies), and food allergies) are common causes of itch in pets, but there are many others. However, even if your cat (or dog) is not allergic to something in the food, highly processed foods that are full of additives (., dry food) can often contribute to itchiness; and getting your pet on a clean, simple diet (such as homemade or raw) will help the body heal overall. Omega-3 fatty acids are anti-inflammatory and extremely helpful for skin conditions. Homeopathy, homotoxicology, and Traditional Chinese Medicine (acupuncture and Chinese herbs) are the alternative therapies most likely to be effective.
