A smelly, brown discharge in your cat's ear often signals ear mites, yeast/bacterial infections, or allergies, with mites producing dark, coffee-ground-like debris, while infections might have a stronger odor and redness, all requiring a vet visit for proper diagnosis and treatment to prevent serious issues like hearing loss.
Black Or Brown Ear Secretions
If your cat is scratching their ear, you may see some black or brown debris fly out. You may also notice a tiny bit seeping out of their ear. If you look inside of their ear, you may see black or brown coffee-like secretions. All of this indicates that mites are present.
Antibiotics – most of the time, antibiotic ear drops are enough to combat an ear infection but if your cat has a very serious or deep ear infection they may need antibiotic tablets or an injection.
Foul odor coming from your cat's ears may be a sign of a severe condition such as an ear mite infestation or an ear infection. It is crucial to get this checked with your veterinarian to prevent it from worsening. It also helps to regularly groom your cat to prevent dirt and bacteria from building up in their ears.
Head shaking. Red, inflamed ears. Thick, yellow ear discharge. Musty odor.
Symptoms of ear mites in cats are relatively easy to recognize if you know what to look for:
The first signs of feline leukemia (FeLV) are often subtle and include loss of appetite, weight loss, lethargy, and a poor coat, but many cats show no signs initially until the virus weakens their immune system, leading to recurrent infections (respiratory, skin, bladder), persistent fever, enlarged lymph nodes, pale gums, and chronic diarrhea. These symptoms stem from FeLV attacking blood cells and suppressing immunity, making cats vulnerable to other illnesses.
Signs and symptoms of ear infections in cats
The answer is simply: NO. Human wet wipes and baby wipes, typically the ones we have on hand, are not suitable for use on pets. In fact, Human wipes can be up to 200 times too acidic for your pet's skin. This is because the pH balance of your pet's skin is very different to that of a human's.
Bacterial or yeast infections and other underlying health conditions can also cause a putrid or musty smell. If your cat's skin is stinkier than usual, pay your vet a visit to get to the bottom of the stench and get your cat's health – and odor – back on track.
Ear mites themselves don't smell, but they can cause a smelly discharge to form within your dog's ears.
The most common signs of ear mites in cats include: Hair or loss or irritation due to excessive scratching around the ears. Dark crusty or waxy discharge from the ear that looks like coffee grounds. Head shaking.
If your cat is leaking brown fluid, it is a sign that they may be dealing with an underlying health issue. The symptoms behind this unpleasant experience are important to understand. If you're concerned, seek out medical attention.
Earwax. Earwax is light brown, dark brown, or orange brown in color. If it gets wet, it can look like a discharge.
Just like humans, pets can have allergies to food or the environment, which can lead to inflammation in the ears and increased wax production.
Ear mites or Otodectes cynotis, are microscopic parasites that live on the skin of the ear canal. Ear mites feed on the ear wax and other oils secreted inside the ear. The brown and black stuff you see inside your cat's ear is called mite debris, which, in layperson's terms, is mite poop!
Diagnosing External Ear Infections (OE)
Your veterinarian will use an otoscope to look down each ear canal to the ear drum (tympanic membrane) to examine the ear canal, look for foreign material, and examine the ear drum. They may also recommend diagnostic tests to look for yeast, bacteria, parasites, or other issues.
Leaving a cat ear infection untreated can lead to severe complications, including chronic pain, hearing loss, and the potential spread of infection to the middle and inner ear. In extreme cases, systemic infection might occur, posing a significant health risk to the cat.
Common Feline Zoonotic Diseases
Many cats with feline leukemia have diarrhea every time they go to the litter box, which can lead to severe dehydration very quickly. Behavioral changes: As the illness progresses, cats may experience frequent behavioral changes. These neurological symptoms are signs that the condition is worsening.
There are stages of FeLV which may impact lifespan, and a cat's viral load may change over time. From available research, progressively infected FeLV+ cats often live between 2-6 years after diagnosis if they were diagnosed as adults, and 6 months-2 years after diagnosis if they were diagnosed as kittens.
Ear Discharge and Crusty Ears
The discharge left behind by mites looks like dark coffee grounds or black pepper. It's usually crumbly or flaky, and it has a musty odor that becomes stronger as the infestation worsens. This material can build up quickly, filling the ear canal and sometimes spilling onto the outer ear.
Apple cider vinegar is a long-used natural remedy for many ailments and conditions, but you may not know how useful it is for treating ear mites in cats. It's an effective antifungal and antibacterial that can be used to treat ear mite infestations, including bacterial or yeast infections.
Ear mites are extremely small, making it difficult to spot them. If you use a soft cloth to wipe the dog's ears, you may be able to spot the mites in the residue. They appear as tiny white dots. Some symptoms to look out for are brown or black waxy ear secretions and a strong odor from the ears.
