Cat Pink Eye: Causes, Symptoms, Treatments, and FAQs
Pink eye, also known as conjunctivitis, is a common eye condition in cats that involves inflammation, redness, and swelling of the conjunctiva, the thin, transparent lining that covers the eye and inner eyelid. It can be caused by a variety of factors, including infections, irritations, and allergies. This article will delve into the causes, symptoms, diagnosis, treatment options, and provide answers to some common questions about cat pink eye.
What is Cat Pink Eye?
"Pink eye" isn't a specific disease, but a symptom that describes inflammation, redness, irritation, and swelling around the conjunctiva of the eye. The conjunctiva is a thin, transparent to pinkish tissue lining that covers the eye and inner surface of the eyelids. It produces mucus that helps the eyelids glide over the eye without friction. When the conjunctiva becomes inflamed, it causes pink eye, also known as conjunctivitis.
Symptoms of Pink Eye:
Red, inflamed, or swollen eyelids
Increased eye discharge, which may be tears, mucus, or pus
Squinting
Protruding third eyelid
Sensitivity to light
These symptoms can occur in one or both eyes and may be accompanied by other symptoms such as fever, loss of appetite, difficulty breathing, sneezing, runny nose, mouth sores, and drooling.
Causes of Cat Pink Eye:
Infections:
Feline Viral Rhinotracheitis (FVR): Also known as feline herpesvirus, is a common upper respiratory infection that can also cause eye ulcers. Many cats have been exposed to this virus at a young age and are dormant until the cat experiences excessive stress (for example, due to changes at home or illness) and the virus erupts and causes symptoms.
Other viruses, such as feline calicivirus.
Bacterial infections, such as Chlamydophila felis or Mycoplasma.
Secondary bacterial infections: Conjunctivitis of any cause can lead to secondary bacterial infections, which can worsen the symptoms.
Non-Infectious Causes:
Irritants: Foreign objects (e.g., dust, sand) under the eyelid, or exposure to chemicals.
Seasonal or environmental allergies.
Eye tumors or cancer.
Chronic dry eye.
Blocked tear ducts.
Contagiousness of Cat Pink Eye:
Contagious pink eye (for example, caused by feline herpesvirus) is highly contagious among cats! To prevent the spread of infection, affected cats should be isolated in a separate room. When caring for a cat with conjunctivitis, wear protective clothing and wash your hands thoroughly before interacting with other cats or engaging in other activities. While humans and other animals usually don't get feline herpesvirus, some types of bacteria can be transmitted across species, including humans. While it's uncommon for cats to spread bacterial conjunctivitis to humans, washing your hands after handling a cat with pink eye is still a good practice.
Diagnosing Cat Pink Eye:
A veterinarian can diagnose pink eye in a cat through a physical examination. However, to determine the cause of pink eye and rule out other eye problems (such as eye ulcers), further testing may be needed, such as tear production testing, eye pressure testing, and examination with special dyes. If the condition is severe or recurrent, blood tests, biopsies, or infectious disease testing may be necessary.
Treating Cat Pink Eye:
Treatment options vary depending on the individual cat's needs, but typically include the following:
Antibiotics: In the form of eye drops or ointment, and sometimes oral medication. Even for viral infections, antibiotics may be prescribed to prevent complications from secondary bacterial infections.
Anti-inflammatory or pain relief medication: Eye drops, ointment, or oral medication.
Antiviral medication: For viral infections.
Elizabethan collar: To prevent the cat from scratching its eyes and potentially worsening the condition.
Lysine supplements: To help boost the immune system and fight off viral infections.
Isolation: Keep the affected cat separate from other cats to prevent the spread of infection.
Referral: If the condition is severe, complicated, or doesn't improve, your cat may need to be referred to a veterinary ophthalmologist.
Common Questions Answered:
How is cat pink eye treated? Treatment depends on the underlying cause, but typically involves medications to treat infections or reduce inflammation and pain (eye drops/ointment, with or without oral medication). Close monitoring is necessary to ensure healing is taking place.
How long does cat pink eye last? Often, there's significant improvement within the first few days. However, treatment may be needed for up to three weeks. It's important to complete the full course of medication, even if your cat's eye looks better, to prevent recurrence.
Is cat pink eye contagious to humans? Fortunately, most infections causing cat pink eye are not transmissible to humans. However, in rare cases, humans can contract bacterial conjunctivitis from cats, so it's always a good practice to wash your hands after touching or administering medication to a cat with pink eye.
How can I tell if my cat has pink eye? If your cat has pink eye, their eyelids may appear red, inflamed, swollen, or puffy. You may also notice squinting, tearing, mucus eye discharge, or other symptoms. These symptoms can also occur with other eye problems, such as eye ulcers or injuries. Therefore, if you notice any eye symptoms, it's crucial to consult your veterinarian.
Conclusion:
Pink eye or conjunctivitis is a common eye condition in cats that requires prompt treatment. If your cat develops pink eye symptoms, take them to the veterinarian immediately and follow their instructions for treatment. Early diagnosis and treatment can help your cat recover quickly and prevent eye damage.
