If you are looking for cat food that is good for cat dander, it is important to understand the cause of dander. It is comprised of dead skin pieces that cats shed regularly and naturally. Dander isn't an issue on its own. However, if it increases in the amount due to dry skin, it could lead to allergies and enhance the existing problems. So, it would help if you focused on enhancing the moisture content in the skin. If your cat's skin is too dry, it could lead to flakiness which contributes to dander production. So, wet food is preferable if your cat has dander issues.
