Have you noticed your cat’s eyes looking swollen or puffy? Swollen eyes in cats can be alarming, but they’re not uncommon. While some cases are mild and resolve on their own, others could signal an underlying issue that requires immediate attention. Understanding the symptoms, causes, and treatments can help you determine whether it’s time to visit the vet.

🐱 What Does Swollen Eyes in Cats Look Like?

Swollen eyes in cats are typically easy to spot, as the affected eye(s) will appear larger, puffier, or inflamed compared to normal. Sometimes, the swelling may be accompanied by other symptoms that can provide clues about the underlying cause.

Common signs of swollen eyes in cats include:

• Redness around the eye
• Watery or thick discharge
• Squinting or keeping the eye closed
• Rubbing or pawing at the eye
• Swelling of the eyelids
• Cloudiness or changes in the eye’s appearance

If you notice any of these symptoms, it’s essential to monitor your cat closely and assess whether the condition improves or worsens.

🌡️ What Causes Swollen Eyes in Cats?

Swollen eyes can result from a variety of causes, ranging from mild irritants to more serious medical conditions. Below are some of the most common reasons your cat’s eyes may be swollen:

• Conjunctivitis: Also known as pink eye, this is one of the most common causes of eye swelling in cats. It often leads to redness, discharge, and irritation.
• Allergies: Just like humans, cats can have allergic reactions to pollen, dust, or certain chemicals, which may cause their eyes to swell.
• Infections: Bacterial, viral, or fungal infections can lead to eye inflammation and swelling. Feline herpesvirus is a frequent culprit.
• Injury: Trauma to the eye, such as a scratch or foreign object, can result in swelling and discomfort.
• Glaucoma: This serious condition occurs when there’s increased pressure in the eye, leading to swelling, pain, and potential vision loss if untreated.
• Blocked tear ducts: When tear ducts are clogged, it can cause fluid buildup and swelling around the eyes.
• Eye ulcers: Corneal ulcers, often caused by injury or infection, can lead to inflammation and swelling.

It’s important to identify the root cause of the swelling to determine the best course of action. If you’re unsure, consult a veterinarian promptly.

🧐 How to Tell If Your Cat Is in Pain

Cats are masters at hiding pain, but there are subtle cues that may indicate your feline friend is uncomfortable. Along with swollen eyes, watch for these signs:

• Increased hiding or withdrawal
• Changes in appetite or grooming habits
• Vocalizing more or less than usual
• Flinching or pulling away when the eye area is touched
• General lethargy or irritability

According to the ASPCA, over 10% of cats exhibit hiding behavior when they’re stressed or unwell (source). If your cat’s behavior seems off, don’t hesitate to reach out to your vet.

🩺 When to See a Vet

While some cases of swollen eyes may resolve with home care, others require professional attention. Schedule a vet visit if:

• The swelling lasts more than 24–48 hours
• There’s significant redness or discharge
• Your cat is showing signs of pain or distress
• Both eyes are affected
• The swelling is worsening or spreading
• There’s a visible injury or foreign object

Early intervention is key to preventing complications and ensuring your cat’s comfort.

💊 Treatment Options for Swollen Eyes in Cats

The treatment for swollen eyes will depend on the underlying cause. A veterinarian may recommend one or more of the following:

• Eye drops or ointments: These are often prescribed to reduce inflammation, treat infections, or lubricate the eyes.
• Antibiotics: If a bacterial infection is present, oral or topical antibiotics may be necessary.
• Allergy management: For allergy-related swelling, your vet may suggest antihistamines or environmental changes.
• Surgery: In severe cases, such as glaucoma or eye trauma, surgical intervention may be required.
• At-home care: For mild cases, cleaning the eye with a saline solution and preventing your cat from scratching the area can help.

Always follow your vet’s instructions and avoid using over-the-counter medications not specifically designed for cats, as they can be harmful.

🛡️ Preventing Swollen Eyes in Cats

While not all cases of swollen eyes are preventable, there are steps you can take to reduce the risk:

• Keep your cat’s living environment clean and free of irritants like dust and strong chemicals.
• Regularly check your cat’s eyes for signs of redness, discharge, or swelling.
• Ensure your cat’s vaccinations are up to date to protect against infections like feline herpesvirus.
• Provide a balanced diet to support overall health and a strong immune system.
• Minimize your cat’s exposure to potential allergens, such as pollen or certain cleaning products.

By staying proactive, you can help keep your cat’s eyes healthy and prevent discomfort.
