Maximo and I send best wishes for Teddy for his eyes to heal quickly.
In Maxman's case, the pain of his corneal scratches from the under eyelid eyelashes caused him to paw at his eye and create the ulcer. That, and not knowing that he had these corneal scratches, I burned his eyes during bathtime, which caused him to rub his head and eyes.
Great job Cathy seeing the signs and getting Teddy in quickly before it became a more serious problem.
