Understanding Cataracts in Cats
Cataracts in cats refer to the clouding of the lens in one or both eyes, leading to impaired vision or blindness. To better comprehend this condition, let’s explore its definition, causes, as well as the risk factors and predispositions associated with it.
Definition and Causes
Cataracts in cats occur when the lens inside the eye becomes cloudy, hindering the passage of light and compromising vision. The most common cause of cataracts in cats is chronic uveitis, which refers to inflammation within the eye resulting from infection, disease, or trauma. Diseases such as feline leukemia, feline immunodeficiency virus (FIV), feline infectious peritonitis (FIP), and toxoplasma gondii can increase the risk of chronic uveitis and subsequent cataracts.
Inflammation triggered by these underlying conditions can lead to the body’s immune system recognizing the lens as a foreign material, contributing to the formation of cataracts (VCA Canada). Additionally, cataracts in cats can develop due to uveitis, a type of eye inflammation that can occur as a result of infectious diseases like feline immunodeficiency virus, feline leukemia virus, feline infectious peritonitis, and toxoplasmosis. It’s important to note that in many cases, the cause of a cataract in cats remains unknown.
Risk Factors and Predisposition
Several factors can increase a cat’s risk of developing cataracts. Chronic uveitis, as mentioned earlier, is a significant risk factor. Cats with diseases like feline leukemia, FIV, FIP, or toxoplasmosis are more prone to developing cataracts due to the associated uveitis. Traumatic injuries to the eye, such as a penetrating injury, can also lead to the premature formation of cataracts.
Additionally, cats with certain metabolic conditions like diabetes or hypertension may be predisposed to developing cataracts. Older cats often develop cataracts as a natural consequence of the aging process.
Understanding the causes, risk factors, and predispositions associated with cataracts in cats is crucial for early detection and appropriate management. If you notice any changes in your cat’s vision or suspect the presence of cataracts, it’s important to consult with a veterinarian for a proper diagnosis and treatment plan.

Symptoms and Diagnosis of Cataracts
In order to identify and diagnose cataracts in cats, it is important to be aware of the associated symptoms and the diagnostic procedures used by veterinarians.
Behavioral Signs
Cats with cataracts may exhibit certain behavioral signs that indicate vision problems. As cataracts progress, cats may experience hazy eyes in certain types of light, have difficulty seeing well enough to navigate around the home, and struggle with tasks such as going up or down stairs, finding food bowls, or navigating around furniture that has been rearranged. Visually impaired cats may also become less agile, bump into furniture, have difficulty finding their food bowl or litterbox, and be cautious about moving in unfamiliar places. Owners are advised to routinely check their cat’s eyes for changes in the color of the iris or cloudiness and consult a veterinarian if anything unusual is noticed.
Diagnostic Procedures
To diagnose cataracts in cats, veterinarians conduct a thorough ophthalmic exam using specialized instruments. One such instrument is an ophthalmoscope, which allows the veterinarian to examine the lens inside the cat’s eye. This examination helps distinguish between cataracts and other conditions such as nuclear sclerosis, which is an aging change that does not affect vision. Additional tests, such as blood work, blood pressure measurement, and urinalysis, may be recommended to screen for underlying conditions that could contribute to the development of cataracts.
Cataracts can often be diagnosed by general practitioners, but in more complex cases, they may refer the cat to a veterinary ophthalmologist for further evaluation. Ophthalmologists may employ more sophisticated tests to accurately diagnose cataracts in cats. It is important to note that early detection and diagnosis of cataracts can lead to timely intervention and improved outcomes for the cat.
By recognizing the behavioral signs and seeking a proper diagnosis through an ophthalmic examination, cat owners can take the necessary steps towards managing and treating cataracts in their feline companions.
Treatment Options for Cataracts
Cataracts in cats can significantly impact their vision and overall quality of life. Fortunately, there are treatment options available to address this condition. The two primary treatment options for cataracts in cats include surgical intervention and medication management.
Surgical Intervention
Cat cataract surgery is considered the most effective and common treatment for cataracts that significantly impair a cat’s vision. The surgery is typically performed by a veterinary ophthalmologist and involves removing the affected lens or part of it and replacing it with an artificial lens. This procedure is known as phacoemulsification.
Post-surgery care is crucial for a successful recovery. It typically involves applying topical eye medicine for several months to prevent infection and inflammation. Additionally, it’s important to keep the cat in a confined space for at least three weeks to prevent complications such as swelling and bleeding. Following the veterinarian’s instructions and attending regular check-ups are essential to monitor the healing process and ensure the cat’s well-being.
Medication Management
In some cases, cataract surgery may not be feasible due to factors such as significant inflammation. In such instances, medication management is utilized to control inflammation and prevent complications like glaucoma. Medications prescribed by the veterinarian may include anti-inflammatory eye drops or other medications to manage the condition.
It’s important to note that medication management may not reverse the cataract itself, but it can help manage associated inflammation and prevent further complications. Regular follow-up appointments with the veterinarian are crucial to monitor the cat’s condition and adjust the treatment plan as necessary.
It’s important to remember that early detection and diagnosis of cataracts in cats are key to exploring the most appropriate treatment options. If you notice symptoms such as cloudiness or changes in your cat’s eyes, consult with a veterinarian for a proper diagnosis and guidance on the best course of treatment.
Preventative Measures for Cataracts
While cataracts in cats can have various causes, including genetic predisposition, trauma, and underlying diseases such as diabetes, there are certain preventative measures that can help reduce the risk of cataracts in cats. These measures include nutritional considerations and lifestyle adjustments.
Nutritional Considerations
Studies suggest that adequate nutrition plays a crucial role in reducing the risk of cataracts in domestic cats. A balanced diet that includes essential nutrients can promote overall eye health and minimize the development of cataracts.

Regular monitoring of your cat’s eye health and prompt veterinary attention if any symptoms arise is essential for ensuring their overall well-being.
Cataracts in Cats vs. Other Pets
When it comes to cataracts, cats have unique considerations compared to other pets. Let’s explore a comparative analysis of cataracts in cats and the unique considerations involved.
Comparative Analysis
Cataracts, characterized by the clouding of the lens in the eye, are more commonly associated with dogs than cats. Some dog breeds, such as Labrador Retrievers, Boston Terriers, Poodles, and American Cocker Spaniels, are more prone to developing cataracts. Similarly, certain cat breeds, including Himalayans, Birmans, and British Shorthairs, are also more susceptible to cataracts. However, cataracts in cats are generally less common than in humans and dogs (Hill’s Pet Nutrition).
One interesting distinction between cats and other pets is the relationship between cataracts and diabetes. In dogs and humans, diabetes can increase the risk of cataracts. However, cats with diabetes typically do not develop cataracts. This highlights the importance of understanding the unique aspects of cataracts in cats.
Unique Considerations
Cataracts in cats are most commonly associated with older age. As cats age, they may naturally develop cataracts. While certain breeds like Burmese and Himalayan cats are genetically predisposed to cataracts, cats of all ages and breeds can be affected (Hill’s Pet Nutrition). The underlying causes of cataracts in cats can vary. They may develop due to an animal’s inability to metabolize proteins and other body chemicals, or as a result of conditions like diabetes or hypertension. Traumatic injury, exposure to certain drugs or toxic substances, radiation, or electric shock can also contribute to the development of cataracts. In many cases, however, the exact cause of cataracts in cats remains unknown.
Diagnosing cataracts in cats involves an ophthalmic exam using an instrument called an ophthalmoscope to examine the lens inside the eye. It is crucial to distinguish between cataracts and other conditions like nuclear sclerosis, which is an aging change that does not affect vision. Additional tests, such as blood work, blood pressure measurement, and urinalysis, may be recommended to screen for underlying conditions.
Understanding the comparative analysis and unique considerations of cataracts in cats is essential for proper diagnosis and management. If you suspect that your cat may be developing cataracts, consult with a veterinarian who specializes in ophthalmology to ensure the best possible care for your feline companion.
Post-Surgery Care for Cats
After undergoing cataract surgery, cats require special care during the recovery period to ensure optimal healing and minimize the risk of complications. The post-surgery care for cats includes managing the recovery period and providing proper monitoring and follow-up.
