Cataracts In Cats

Dec 26, 2023 | Cats & Kittens | 0 comments

Cataracts are a concerning eye condition that can affect our beloved feline companions. Just like in humans, cataracts in cats can lead to impaired vision or even blindness if left untreated.

Let’s discover what cataracts are, their symptoms, causes, diagnosis, treatment options, and tips for providing a comfortable life for your cat with cataracts.

What Is Cataract in Cats?

Feline cataracts are a complex and visually impairing condition that affects the eye’s lens, an ordinarily transparent structure responsible for focusing light onto the retina at the back of the eye. This lens is crystal clear in a healthy eye, allowing light to pass through and create a sharp image.

However, when a cataract develops, the lens becomes cloudy or opaque, obstructing the passage of light and distorting vision. Cataracts can vary in size and severity, ranging from small, inconspicuous clouding to significant opacities that obscure entirely the lens.

The extent of the cataract determines the impact on a cat’s vision, from mild blurriness to complete blindness.

This condition can occur in one or both eyes, and while it can affect cats of all ages, it is more commonly observed in older felines. As cataracts progress, they compromise the cat’s ability to see clearly, ultimately affecting its quality of life.

Symptoms of Cataracts in Cats

Cataracts in cats manifest through various noticeable symptoms, which can vary in intensity depending on the size and progression of the cataract. If you suspect your cat may have cataracts, here are some common signs to watch out for:

  • Cloudy or Opaque Eyes

One of the most apparent signs of cataracts in cats is the clouding or opaqueness of the eye’s lens. The affected eye may appear hazy, making it challenging to see the usual clarity of the lens.

  • Changes in Behavior

Cats with cataracts often exhibit changes in behavior. They may become more cautious or reluctant to engage in activities that require precise vision, such as jumping onto high surfaces or playing with small toys.

  • Bumping into Objects

Impaired vision can lead to cats bumping into objects or walls as they struggle to navigate their surroundings accurately.

  • Squinting or Light Sensitivity

Cataract-afflicted cats may squint or exhibit sensitivity to light, often seeking darker areas to avoid discomfort caused by increased light exposure.

  • Dilated Pupils

Dilated pupils in cats with cataracts can result from the reduced light entering the eye due to the clouded lens. This dilation captures as much available light as possible, compensating for their compromised vision.

  • Vision Problems

As cataracts progress, cats may experience various vision problems, such as difficulty tracking moving objects or discerning details in their environment.

If you notice any of these symptoms in your cat, it’s essential to consult with a veterinarian promptly. Early detection and appropriate treatment can significantly improve your cat’s prognosis and quality of life.

Causes of Cataracts in Cats

Cataracts in cats can arise from various factors, including:

  • Genetics: Some cat breeds are genetically predisposed to cataracts, making them more susceptible to developing this eye condition.
  • Underlying Health Issues: Cataracts can occur as a secondary condition due to other health problems, such as diabetes mellitus. Managing these underlying issues is crucial to prevent or slow down cataract progression.
  • Aging: As cats age, the risk of cataract development increases, with senior cats being more prone to age-related cataracts.
  • Trauma or Injury: Eye injuries or trauma can lead to the formation of cataracts in cats, particularly if the lens is damaged during the incident.
  • Nutritional Deficiencies: Poor nutrition and imbalances in a cat’s diet may play a role in cataract formation, emphasizing the importance of a well-balanced diet.
  • Inflammation or Infection: Eye infections or chronic inflammation within the eye can contribute to cataract development over time.

Diagnosis of Cataracts in Cats

Accurately diagnosing cataracts in cats is crucial for determining the appropriate treatment plan. Veterinary professionals employ a combination of methods and examinations to confirm the presence and severity of cataracts. Here’s an overview of the diagnostic process:

Physical Examination

The first step in diagnosing cataracts in cats involves a thorough physical examination. The veterinarian will assess your cat’s overall health, including their eyes, to identify any visible signs of cataracts.

Slit Lamp Examination

To get a closer look at the eye’s internal structures, veterinarians often use a specialized instrument called a slit lamp. This tool allows for detailed inspection of the lens and the extent of the cataract.

Eye Tests

Various eye tests may be conducted to evaluate your cat’s vision and the impact of the cataract. These tests may include assessing your cat’s response to light, evaluating its ability to track moving objects and measuring the pressure within the eye.

Retinal Examination

A retinal examination may be performed to check for any damage to the retina, which can result from cataract formation.


In some cases, an ultrasound examination may be necessary to assess the cataract’s location and size, especially if the cataract is in the early stages and not easily visible.

The combination of these diagnostic methods allows veterinarians to confirm the presence of cataracts and determine the cataract’s severity and any potential complications.

With a precise diagnosis, the veterinarian can discuss treatment options and strategies to manage the condition effectively and enhance your cat’s quality of life.

Treatment Options for Cataracts in Cats

When it comes to addressing cataracts in cats, the choice of treatment depends on several factors, including the cataract’s severity and your cat’s overall health and age. Veterinarians carefully assess these variables to determine the most appropriate course of action. Here are the primary treatment options:

  • Cataract Surgery: In many cases, cataract surgery is the most effective option for restoring a cat’s vision. During this procedure, the clouded lens is surgically removed and replaced with an artificial intraocular lens (IOL) or a contact lens. The success of the surgery largely depends on factors such as the cataract stage and the cat’s general health.
  • Medical Management: Medical management is an alternative for cats with early-stage cataracts or those who may not be suitable candidates for surgery due to underlying health issues. This approach involves using prescription eye drops or medications to reduce inflammation and manage symptoms.
  • Lifestyle and Environmental Adjustments: Regardless of the chosen treatment path, adjusting your cat’s environment is crucial. Ensure their living space is safe and obstacle-free, with consistent pathways to help them navigate confidently.

Cataracts in cats is a progressive condition, and timely intervention is key to achieving the best outcomes. Regular check-ups with a veterinarian, especially if your cat is in a high-risk group or displays symptoms of cataracts, can aid in early detection and appropriate treatment planning.


Cataracts in cats can be challenging, but with early detection and proper care, you can help your feline friend enjoy a fulfilling life. Regular veterinary check-ups, prompt treatment, and a supportive home environment are vital in managing cataracts and ensuring your cat’s well-being.

Can cataracts in cats be prevented?

Cataracts related to genetics or aging cannot be prevented, but you can reduce the risk of secondary cataracts by managing your cat’s overall health.

Is cataract surgery safe for cats?

Cataract surgery is generally safe for cats when performed by a skilled veterinarian. It can significantly improve their quality of life.

Not necessarily. Mild cataracts may not affect a cat’s vision significantly, but it’s essential to consult a veterinarian for proper evaluation.

Can cataracts in cats be reversed with medication?

Medication can manage some symptoms but usually cannot reverse cataracts. Surgery is the primary treatment for restoring vision.

Are confident cat breeds more prone to cataracts?

Some breeds, such as Persian and Siamese cats, have a higher genetic predisposition to cataracts. Regular check-ups are essential for these breeds.
