Feline Ear Disorders

Suggested Articles

A wide range of afflictions can cause discomfort; some may even lead to deafness. Here’s how to protect your cat.

Among a normal, healthy, and properly cared-for cat’s many distinctive attributes is its astoundingly acute sense of hearing. While the human auditory system is capable of detecting sounds ranging in frequency up to about 20,000 vibrations per second, cats typically can sense sounds pulsating at 60,000 vibrations per second or greater. This impressive acoustic sensitivity has been honed over the ages to serve a cat in countless ways—signaling the stealthy approach of a dangerous predator, for example, or detecting the underground movement of a burrowing rodent.

Although most cats will go through life without experiencing a serious problem with their ears, owners should know that a variety of conditions—including congenital defects, infections, trauma and age-related changes—can be extremely painful and may compromise an animal’s hearing. Most feline ear disorders are readily treatable and will not result in permanent hearing loss, notes James Flanders, DVM, an associate professor of surgery at Cornell University’s College of Veterinary Medicine. However, some conditions may render a cat partially or totally deaf, especially if they remain unrecognized and untreated.

Ear Anatomy

A cat’s ears, like those of other mammals, are made up of three structural areas: the outer ear, middle ear and inner ear. The outer ear consists of the external earflap (pinna), and the ear canal—a narrow tubular passage through which sound vibrations enter the ear from the outside environment.

The middle ear contains the eardrum, a taut membrane that vibrates according to the incoming sound waves, and the auditory ossicles, small bones that transmit the eardrum vibrations to the inner ear. And the inner ear—located deeper within the skull—contains the cochlea, a snail-shaped structure containing nerve endings that receive the vibrations and passes them along to the brain, thereby enabling a cat’s hearing. The inner ear is also the site of the vestibular system, a complex arrangement of nerves and receptors that govern a cat’s sense of balance.

Congenital Conditions

Some feline ear abnormalities are genetically transferred from parents to offspring. Among these is an inherited condition known as “fold-ears,” in which the tip of a cat’s pinna is bent sharply either toward or away from the skull. This bizarre condition is not often associated with hearing loss. However, cats whose ears are unusually distorted in this manner frequently experience accompanying skeletal problems that may have troublesome consequences.

Another primarily heritable abnormality, says Dr. Flanders, is atresia—a defect in the development of the ear canal that may result in partial or total obstruction of the channel. “In this condition,” he points out, “a wall develops in the ear canal that makes it difficult or impossible for sound to reach the cochlea. It’s sometimes operable, and if this wall can be removed, hearing can potentially be restored.”

Some cats are born deaf, and the disability cannot be corrected. Due to an anomaly in their genetic makeup, white cats with blue eyes are at greatest risk for congenital deafness. Indeed, says Dr. Flanders, “About 80 percent of white cats with two blue eyes will start to show signs of deafness when they are about four days old as the result of cochlear degeneration.”

Acquired Disorders

The great majority of feline ear disorders are acquired. A cat that fights a lot or is in the habit of scratching its ears excessively, for example, might experience hematoma, a collection of blood from broken vessels that collects between the skin covering the ear and the underlying cartilage. Cats may also be afflicted by various polyps (small growths protruding from the surface of a mucous membrane) and squamous cell carcinoma—a cancer that can emerge on the ear tips and is especially common in cats that are frequently exposed to harsh sunlight.

Owners should also keep in mind that a cat’s eardrum thickens with age. Thus, hearing difficulties and potential deafness are often found in geriatric cats. Moreover, deafness can occur as a side effect of various medications—certain antibiotics or diuretics, for example.

Among all acquired feline ear conditions, Dr. Flanders notes, the most common by far is otitis externa, an infection of the outer ear canal. This disorder results from infestation of the ear canal with infectious agents, usually ear mites.

Otitis externa is most prevalent in cats that are especially susceptible to seborrhea, a skin ailment marked by excess oily secretions from the sebaceous glands. This results in the accumulation of surplus ear wax in which invading mites, bacteria, and other organisms can flourish. If otitis externa is not appropriately treated, the infection can migrate to the middle ear, where it is termed otitis media, and to the inner ear (otitis interna). In the most severe cases, the ear drum and inner ear can be irreparably damaged, resulting in deafness and—because of the condition’s impact on the vestibular system—an acute disturbance of balance on the affected side or sides.

Reducing the Risk

Most feline ear disorders, including otitis externa, can be treated with medicine, says Dr. Flanders, although surgery may sometimes be the only option. Unfortunately, deafness in one or both ears is most often a permanent condition.

A few simple measures, he points out, will substantially reduce the chances that a cat will experience a serious ear disorder. He advises the following:

  • Minimize the amount of time that your cat—especially if it is white or lightly pigmented—is exposed to direct sunlight.
  • Maintain a clean environment that will discourage the proliferation of ear mites and other potentially infectious agents.
  • Routinely examine your cat’s ears for such signs of infection as swelling, discharge, discoloration and the collection of dirt and debris.

If you observe your cat persistently scratching at its ears, do not probe into them to find the cause. Instead, consult your veterinarian as soon as possible.

Feral Cats in Florida: Does Ear Clipping Hurt the Animal?

Feral Cats in Florida

Have you ever seen a clipped ear cat and wondered what it meant? Feral cats in Florida are often part of trap-neuter-release (TNR) programs, which are critical for managing the population of homeless cats in the wild. Clipping a cat’s ear (also called ear-tipping) after it has been neutered or spayed signals to the community that organizers don’t need to spend time and resources trapping a feral cat and prepping it for the procedure.

Is There a Case to be Made for Fewer Clipped Ear Cats?

Many animal lovers and pet owners often wonder whether clipped ear cats are harmed in any way throughout this process—and whether ear-tipping specifically hurts the animals. This level of compassion comes from a positive place and shows that our communities are full of people who want to protect our furry friends. But the reality is that the process of clipping a cat’s ear is almost entirely painless. And TNR programs save hundreds of cat’s each year , playing an essential role in minimizing the number of feral cats in Florida who aren’t in loving homes.

What Steps Do Veterinarians Take for the Safety of Clipped Ear Cats?

No other method of identifying neutered and spayed feral cats has proven to be as safe and effective as ear-tipping. And there is a list of precautions that veterinarians take to ensure that the procedure is safe and as painless as possible.

1. Anesthetize the Cat

The cat will be under anesthesia for the spaying or neutering procedure, so the animal won’t feel a thing—just like when humans have surgeries or get moles removed.

2. Examine the Ears

As a service to the cat, and to help improve the overall health of feral cats in Florida, veterinarians will examine the cat’s ear for mites, debris and infections, treating the animal as necessary.

3. Carefully Apply a Sterile Scrub

Vets will then apply a sterile scrub to the top portion of the cat’s left ear (the procedure calls for removing only the top 1 cm). Doing so will prevent the solution from entering the ear canal.

4. Make a Clean Cut

Scalpel blades or sharp scissors are used, along with a hemostat (a clamp-like instrument that prevents the flow of blood), to minimize bleeding. The goal is to create a clean straight line that can’t be confused with bite wounds or other ear injuries a feral cat might acquire in its lifetime.

5. Apply a Hemostatic Paste

This paste, which vets have ready as soon as the ear has been clipped, is applied with a cotton ball to stop bleeding. And the lidocaine in the mixture will lessen any discomfort the cat may feel once it’s awake, reducing head shaking.

Veterinary professionals take every safety precaution possible with clipped ear cats because they care about improving the lives of feral cats in Florida, and across the United States. Animal lovers everywhere can rest assured that ear-tipping doesn’t hurt the cat any more than a routine trip to the dentist hurts a human.
