Advice on cat eye infection treatment from Dr. Patrick McHale, DVM from the www.cat-health-guide.org Like humans, cats can get an eye infection too. Anytime there are any kinds of problems with the cat eye, you are encouraged to visit a veterinarian as soon as possible. The veterinarian will determine if there is a common cause, such as a corneal scratch or bacterial infection. Most cases are uncomplicated bacterial infections of the eye that will respond to eye drops. There are other more complicated things that can happen in the eye, and a physical examination will help to determine that.
