How to tell if a kitten is healthy before you adopt it
Look into the kitten's eyes.
A kitten's eyes should be clear and bright. They shouldn't be runny, for instance, and they should also be able to focus easily on your finger.
If you notice discharge around the eyes, that could indicate a protruding third eyelid, swollen conjunctiva, or another health problem. Conjunctivitis is a common feline eye disorder where the mucus membrane located on the inside of the eyelid becomes inflamed and coats the eyeball.
