I noticed that my cat has been scratching his ears lately. Today when I looked inside I saw teeny tiny black specs. I’m not sure if it just dirt or is it is flea feces.
It could be dirt or mites in the ears. Take him to your veterinarian to check the inner part of the ear with the otoscope. If it is dirt your vet can clean his ears correctly, and if they are mites you will be given the corresponding treatment.
All the best,
