To remove black chin in cats, you can use saline solution, soapy water, or tea to wipe the cat's chin daily for 1-2 weeks. This can reduce inflammation, clean the area, and help fade the black chin.
If there is redness, swelling, or hair loss on the chin, you can apply antibiotic skin medications such as erythromycin cream or mupirocin ointment for treatment. If ulceration occurs on the chin, you should seek medical attention promptly and receive treatment with oral medications and antibiotic skin medications.
