Unfortunately it's really hard to tell from the picture, because many skin issues look the same in a cat. I would be concerned about an allergy (allergies to fleas, food, or the environment being the most common causes), or possibly a skin parasite that is causing itching. I would recommend a vet visit for a simple test called a skin scrap in which they will look at some skin cells under the microscope to see if they can find any organisms, and then treat accordingly. Good luck!
