On Friday I noticed him run head-first into several things. I took him to the vet this evening and he is completely blind. She said it is likely hereditary,and that he has likely been blind for 3 months,but she did a few tests to make sure. I'm still waiting for the results of them. But if it is neither of the things she tested for, he is permanently blind and he is only 2 years old... I'm still in shock. Please pray for us. Thank you!
