Cat Scratching Ears or Shaking Head? Black Wax, Ear Mites, Infections
๐จ Check first
If your cat shakes their head violently or scratches the base of their ears until they bleed, severe inflammation or parasite infection is present inside the ear. Sticking cotton swabs deep into the ear canal like humans do pushes wax deeper and risks injury, so avoid this completely.
๐ The answer in 3 seconds
- Massive amounts of dry, black coffee-ground-like ear wax accompanied by intense itching point to ear mite infestations, while sticky brown or yellow wax with a sour odor points to otitis externa caused by Malassezia yeast or bacteria.
- Because feline ear canals are L-shaped, home care should focus strictly on wiping visible parts of the outer ear flap surface with a damp cotton ball.
- Because ear mites spread easily among cats, multi-cat households require simultaneous treatment for all cats using vet-prescribed spot-on parasite treatments or ear drops.
๐ Flowchart
- Step 1Flip the ear flap back and take smartphone photos to check ear wax color and texture (dry black crumbs vs. sticky brown wax), redness, swelling, heat, and unusual odors.
- Step 2Without inserting anything into the ear canal, wipe accessible folds of the outer ear surface gently using cotton moistened with pet ear cleaner or warm water.
- Step 3Leave some ear wax uncleaned and visit a vet so they can examine scrapings under a microscope to identify ear mites, bacteria, or fungi and prescribe suitable ear drops.
โญ Step-by-step fix
Step 1 ยท What you can do at home right now
Flip the ear flap back and take smartphone photos to check ear wax color and texture (dry black crumbs vs. sticky brown wax), redness, swelling, heat, and unusual odors.
Step 2
Without inserting anything into the ear canal, wipe accessible folds of the outer ear surface gently using cotton moistened with pet ear cleaner or warm water.
Step 3
Leave some ear wax uncleaned and visit a vet so they can examine scrapings under a microscope to identify ear mites, bacteria, or fungi and prescribe suitable ear drops.
โ Never do this
- Inserting rigid human cotton swabs deep into the ear canal to scrub (risking eardrum or ear canal injury if the cat shakes its head, and packing wax deeper).
- Leaving severe head shaking unaddressed for weeks (rupturing blood vessels within ear cartilage and causing a ballooning hematoma called an aural hematoma requiring surgery).
