Cat Shampoo Recipe. This simple recipe creates an affective and gentle oatmeal shampoo that can help soothe irritated skin. Finally, brush out the coat again, and finish off the cleanup with a dry towel, getting off as much of the mixture as possible.

While we humans use dry shampoo on occasion, it is typically made with cornstarch and alcohol. Use a food processor, blender, or coffee mill to grind the oatmeal into a coarse floury texture. Pour this mixture over your cat’s fur before using your fingers to massage it through their fur and down to their skin.
