We were at a friends house last night, where he has been before, but for shorter periods of time. They have a dog, a cat, and smoke. After being there for about an hour, his eyes started to itch him, got red and a little swollen. Today, they are still red, and he is still itching them a little bit, the swelling has gone down. He has been at other houses with pets and not had this reaction.
I have not given him any medication, but I am concerned about his eyes.
On another note, he also started back at day-care after being gone for a month, could it be pink eye? They are not goopy at all.
