There is black stuff on the male cat’s testicles:

1. It may be dirt. It is recommended to use a pet-specific wet wipe to wipe the surface of the male cat’s scrotum, which can generally be wiped clean.

2. It may be due to melanin deposition. It is recommended to check whether the surface of the male cat’s scrotum is accompanied by redness, heat and swelling. At the same time, you can gently press the testicles to see if the cat has any symptoms of discomfort.

3. If no abnormality is found, you can focus on observation first.

4. If any abnormalities are found, you need to take the cat to a pet hospital for professional diagnosis and treatment.
