Deafness in Cats: A 2025 Veterinary Guide to Causes, Symptoms & Care 🐱🔇

By Dr. Duncan Houston, BVSc

Deafness in cats can be either congenital (present at birth) or acquired due to various factors such as infections, trauma, or aging. Understanding the causes, recognizing the signs, and knowing how to care for a deaf cat are essential for ensuring their safety and quality of life.

Understanding Deafness in Cats 🧠

Deafness occurs when a cat loses the ability to hear in one or both ears. It can result from:

• Congenital Factors: Genetic mutations, particularly in white cats with blue eyes, can lead to deafness. Approximately 65-85% of white cats with two blue eyes are deaf. [Source]
• Acquired Causes: These include chronic ear infections, exposure to ototoxic drugs, trauma, tumors, and age-related degeneration.

Symptoms of Deafness 🔍

Signs that your cat may be experiencing hearing loss include:

• Not responding to sounds or their name
• Frequent meowing or louder vocalizations
• Startling easily when approached
• Head tilting or ear twitching
• Behavioral changes such as increased hiding

It's important to note that cats with hearing loss in only one ear may not show obvious symptoms.

Diagnosis 🩺

If you suspect your cat is deaf, consult a veterinarian. Diagnosis may involve:

• Physical Examination: Checking for signs of ear infections, wax buildup, or structural abnormalities.
• BAER Test (Brainstem Auditory Evoked Response): This specialized test measures the electrical activity in the brain in response to sound stimuli and is the most accurate method for diagnosing deafness.

Treatment and Management 💊

While congenital deafness is irreversible, some cases of acquired deafness may be treatable:

• Medications: Treating underlying infections or inflammation with appropriate antibiotics or anti-inflammatory drugs.
• Surgical Intervention: Removal of tumors or polyps that may be causing hearing loss.

For cats with permanent hearing loss, management focuses on ensuring safety and effective communication:

• Use visual cues or hand signals for communication.
• Keep your cat indoors to protect them from dangers they can't hear, such as traffic or predators.
• Ensure a consistent routine to provide a sense of security.

Living with a Deaf Cat 🐾

Deaf cats can lead happy and fulfilling lives with the right care:

• Safety: Avoid startling your cat by approaching them within their line of sight.
• Enrichment: Provide toys and activities that stimulate their other senses, such as touch and sight.
• Training: Use positive reinforcement with visual cues to teach behaviors and commands.

Deafness in cats, whether congenital or acquired, requires attentive care and adjustments to ensure their well-being. By understanding the causes and implementing appropriate management strategies, you can help your deaf cat live a safe and contented life.
