Noticing your cat squinting, pawing at their face, or dealing with watery, irritated eyes can be concerning. Eye infections are common in cats, and while many cases are mild, some may require prompt veterinary care. Knowing the signs and how to help can make all the difference in your cat’s comfort and recovery.

⚠️ What to Watch For

Eye infections in cats can present in various ways. Paying close attention to your cat’s eyes and overall behavior can help you spot potential problems early. Here are the key symptoms to watch for:

  • Redness or swelling around the eyes
  • Watery, yellow, or green discharge
  • Squinting or keeping one eye closed
  • Frequent pawing or rubbing at the face
  • Crusty buildup around the eyes
  • Cloudy appearance of the eye
  • Sensitivity to light

If you notice one or more of these symptoms, your cat may have an eye infection or another underlying issue. Some eye conditions resolve on their own, but others may worsen without treatment, so monitoring is essential.

🔍 Possible Causes

Several factors can cause eye infections in cats. Understanding the root cause can guide treatment and help prevent future problems. Here are the most common culprits:

  • Conjunctivitis: Often referred to as “pink eye,” this is the inflammation of the conjunctiva, the tissue lining the eyelids and covering the white part of the eye.
  • Upper Respiratory Infections: Viruses like feline herpesvirus or calicivirus can lead to respiratory symptoms and eye issues.
  • Eye Injuries: Scratches or foreign objects in the eye can lead to infections.
  • Allergies: Environmental allergens, such as pollen or dust, can irritate your cat’s eyes.
  • Corneal Ulcers: Open sores on the cornea can result from trauma, infections, or underlying conditions.
  • Blocked Tear Ducts: Improper drainage can lead to watery eyes and secondary infections.

Some cats, especially kittens or those with weakened immune systems, are more prone to eye infections. Additionally, cats living in multi-cat households or shelters may face higher exposure to contagious conditions.

✅ What You Can Do at Home

While some cases of eye irritation can be managed at home, it’s important to proceed cautiously. If your cat shows mild symptoms, here are a few things you can try:

  • Gently clean the eyes: Use a soft, damp cloth or sterile saline solution to wipe away discharge. Always use a fresh cloth for each eye to prevent spreading infection.
  • Reduce allergens: If you suspect environmental allergens, clean your home and wash your cat’s bedding regularly to minimize irritants.
  • Keep their surroundings calm: Stress can worsen some infections, especially those linked to feline herpesvirus. A quiet, low-stress environment can help your cat recover faster.

It’s crucial to avoid using over-the-counter medications or eye drops meant for humans, as they may harm your cat. If the symptoms don’t improve within 24–48 hours or worsen, consult a veterinarian for further guidance.

💡 When to Call a Vet

Not all eye infections can be treated at home. If your cat’s symptoms persist or worsen, it’s time to seek veterinary care. Here are some scenarios where professional help is essential:

  • Severe redness, swelling, or discharge
  • Painful behavior, such as pawing or vocalizing
  • Cloudiness, changes in eye color, or vision loss
  • Signs of an upper respiratory infection, like sneezing or nasal discharge
  • Symptoms lasting longer than 48 hours without improvement

During a veterinary consultation, your vet may perform an eye exam, take swabs for testing, or use fluorescein dye to check for corneal ulcers. Treatment will depend on the cause and may include prescription eye drops, antibiotics, or antiviral medications. In some cases, addressing an underlying condition like allergies or a respiratory infection is necessary to resolve the eye issue.

FAQs

Q: Can I use human eye drops on my cat?
A: No, you should never use human eye drops on your cat unless directed by a veterinarian. Many human medications can harm cats or worsen their condition.

Q: How can I prevent eye infections in my cat?
A: Regularly clean your cat’s face, keep their living area clean, and ensure they stay up-to-date on vaccinations to prevent infections linked to viruses. Minimizing exposure to other sick animals can also help.
