If a cat has black stuff in its ears, it usually means it has ear mites. The cleaning method is as follows:

1. Clean the ears thoroughly with a sterile cotton swab dipped in hydrogen peroxide and let them dry.

2. Sprinkle boric acid powder. If it is not available, you can use Dermatitis Powder instead and apply it evenly.

3. If you are worried that there is a problem in the ear canal but do not dare to rub deeply, you can put a few drops of nitroglycerin ear drops, French Vic ear drops, or 886 liniment to cover the cat's ears. Knead gently, then let go and let the cat shake its head to shake out the dirt in the ear canal, and then repeat the steps.

4. You must insist on taking medication until it is completely eliminated.

5. Be sure to keep the ears dry. Ear mites can easily die in a dry environment.

Methods to determine whether a cat has ear mites

Whether a cat has ear mites can be determined from clinical symptoms. First of all, if a cat has itching around its ears, it will frequently scratch its ears with its hind limbs. Secondly, if you open the cat's ears, you will find a large amount of dark brown secretion in the ear canal. In severe cases, it will produce foul odor, abscess, bleeding, etc. Finally, after illumination, small white insects can be seen crawling in the ear. Therefore, ear mite drugs should be used for treatment in time.
