Understanding Cat Conjunctivitis: Symptoms and Causes
As cat owners, we may occasionally notice our feline friends with redness and swelling around their eyes. This can raise concerns about injuries or issues related to their food. If left unmonitored, symptoms may progress to excessive tearing and frequent blinking. If the redness and swelling worsen, it may indicate cat conjunctivitis.
What is Cat Conjunctivitis?
Conjunctivitis refers to inflammation of the conjunctiva, the tissue lining the eyelids and covering the front of the eye. It contains many blood vessels, which can become congested and swollen when irritated or infected. Cat conjunctivitis should be suspected if you notice a pink line or redness around your cat’s eyes. Gently flipping their eyelid can help identify the inflamed conjunctiva.
Symptoms of Conjunctivitis in Cat
Increased discharge, watering eyes, and difficulty keeping the eyes open are signs of conjunctivitis. If your cat squints or shows signs of a viral infection, it may also exhibit a runny nose and decreased appetite. Cats with conjunctivitis may avoid bright light or struggle to see.
If severe, conjunctivitis can lead to swelling, corneal ulcers, and even cornea perforation, which can cause blindness. If untreated, prolonged inflammation may lead to respiratory distress, fever, or diarrhoea.
Causes
Upper respiratory infections, bacterial infections, allergies, and foreign objects are the most common causes of conjunctivitis in cats. Treatments often involve topical medications, usually eye drops, that help reduce symptoms.
Cat litter is another common contributor to conjunctivitis. If your cat experiences severe conjunctivitis, consider changing the type of litter or ensuring it’s cleaned frequently.
Types of Infection-Related Conjunctivitis
Conjunctivitis can be categorized into infectious and non-infectious causes. Infectious conjunctivitis often results from viruses or bacteria, with herpes, calicivirus, and chlamydia typical culprits. Feline herpesvirus, in particular, is prevalent and, while treatable, can lead to recurring issues if the cat’s immune system weakens.
Non-infectious causes are typically allergic reactions, often triggered by pollen, dust, or other irritants.
Importance of Veterinary Care
If you notice symptoms of conjunctivitis in your cat, it’s crucial to visit a veterinarian promptly. With appropriate treatment, including eye drops, antibiotics, or other medications, most cats show improvement within 1-2 weeks. Treatment varies based on the underlying cause, making an accurate diagnosis essential for effective care.
