Cats with runny brown eye droppings may be caused by diet, bacterial infection, etc. Firstly, check if the food you normally give your cat is high in oil and salt, and make sure it is a light diet. Secondly, a cat living in a poor environment may also have a runny brown discharge. Finally, cats with infected eyes such as bacteria and viruses will also have runny brown discharge or increased discharge, and this condition is recommended to be checked and treated at the vet.
