I've had Fred for almost 10 years now and his eye color suddenly changed. He has lived in the basement for some time and does have a heat lamp and a heating pad. He has been sleeping an awful lot so I think he's been in brumation. There is a possibility he is sick though because he hasn't been acting right either. Just very lackadaisical and has no desire to eat. Can anyone help me figure out why his eyes are this strange? They were never like this before. It seems like his pupils are ruptured and his eye color has completely changed
