do follow the suggestions by the other posters..
and do try and get some antibiotic eye drops or ointment (for eyes)..
he is cheeping because he is stressed, and fearful..he can't see..
he also might might be in some pain.
hope you are keeping him warm and safe, preferably in a small confined area with food and water close by.
after you get the eye cleaned and applied the eye drops..his vision might still be cloudy for a while, and he might even walk funny due to the vision not being right.
hope his eyes are ok..
