Hi, Welcome to JustAnswer. I am a licensed veterinarian and I'm here to help you. It does sound like Maurice has/had a respiratory tract infection and is getting some better. Your nursing choices and skills for him are very correct, and I can make just a couple of suggestions. If you normally feed him hamster pellets, it would be good to encourage these as they have fiber that is good for his teeth and his gut. You may need to soak these in water. Secondly, it would be great to get him on systemic as well as eye antibiotics. Are you able to buy these over the counter there in drug stores?
