Ok, so I went to take my hamster out of his cage, after 3 days of rest. When I lifted him up, he turned his head. On his left eye was a big black thing covering his eye socket. I thought it was bedding, or food stuck in it. So, I take him to petsmart. They DO NOT WORK ON RODENTS. Are you kidding me, I bought him here. So we get home, and I take him out of his ball. I notice the black stuff is gone. It was his eye. Oh my god. It was so gross. What should I do after I clean it.
