What is conjunctivitis in cats?           

Cat conjunctivitis is the inflammation of the thin membrane inside the eyelid and the white area of the eye. This is very uncomfortable for the cat because the conjunctiva (mucous membrane of the eye) becomes red and swollen. Additionally, the affected eye may also start to leak some discharge.

Cat Conjunctivitis can be both, infectious and non-infectious. Infected conjunctivitis is caused by bacteria and viruses whereas non-infectious conjunctivitis is usually the result of a foreign object irritating the eye.

What causes conjunctivitis in cats?

Feline conjunctivitis has different causes based on the type that is affecting your cat. That is why it is important to consult a vet to get a proper pink eye diagnosis. Some popular causes of cat conjunctivitis are discussed below.

Non-Infectious conjunctivitis – Purina explains that this illness usually happens when environmental irritants enter your cat’s eyes. Irritants like smoke, dust, air fresheners, and even shampoo can cause redness in the eyes. Even if you are using a pet shampoo, the possibility of your cat developing conjunctivitis is still there. Therefore, it is always a good idea to be careful when bathing your cat. 

Bacterial infection – This is the first type of infectious conjunctivitis. Bacteria, such as Streptococci, Staphylococci, and Chlamydophila, can all cause pink eye in cats. These infections are not localized to the eyes and are usually accompanied by respiratory problems. This type of conjunctivitis is contagious between cats.
