That black gunky stuff in your cat’s stinky ear should never be ignored.

A buildup of black “stuff” in a cat’s ear needs immediate medical attention – because most likely, it’s being caused by bugs – as in very tiny mites – tons of them.


However, what appears to be black “stuff” in a cat’s ear can also be caused by cancer.

The cancer will not produce a foul odor, and not all ear mite infestations cause a bad smell, either.

Cat’s Ear Has Black Stuff in It & Has Foul Odor

“Ear mites are the most common cause of the black stuff in your cat’s ear,” says world-renowned integrative veterinarian Carol Osborne, DVM, at Chagrin Falls Pet Clinic, and creator of PAAWS: Pet Anti-Aging Wellness System for dogs and cats.

“The black stuff is actually a mixture of wax, mites, blood and debris carried in from the ear mites,” continues Dr. Osborne.

“Your cat’s ear, if heavily infected with mites, will usually give off a pungent odor. There are many treatments for ear mites.

“Generally your veterinarian will need to clean them out thoroughly, and then they will send you home with special drops to be massaged into your cat’s ear.

“It’s important to remember this black stuff is not comfortable for your cat, so if you are going to try and clean your cat’s ears first by yourself, be very gentle, as your cat’s ears will generally be inflamed, making your cat very sensitive to such cleanings.”

Don’t take on this task without at least speaking to your veterinarian.

Squamous Cell Carcinoma

This cancer usually appears pink to dark red, but can also appear black.
