I have a cat who is about 3 years old and she is keeping her eye closed. When she does open in the lining of her eye is red and puffy. There is discharge but it is clear like tears. She may have had a smack from the new kitten but we dont see a wound. I have also had someone mention conjunctivitis. Not really sure what to do but we would like to take care of it at home if that is possible.
