Poor Jaxton! It's definitely not normal to have to clean mucus out of his eyes so often, so I would say that something is definitely wrong. He may have an eye infection, or a chronic problem such as dry eye (keratoconjunctivitis sicca, or KCS) that causes his eyes to not produce enough tears. This is a very common cause of a constant "film" and/or thick yellow or green mucus in the eyes. I would recommend having him examined by a vet as soon as you are able to - he/she can do some simple diagnostic tests to help determine the problem and get him started on appropriate medication to treat it.
