I just picked up a ten year old red tail boa for my reptile rescue, Forgotten Friend Reptile Sanctuary. She is a very beautiful specimen who seems very healthy despite appearing underfed. There is one problem I noticed right away though. One of her eyes is completely fogged over, I'd say even more so than when a boa sheds. Is this the sign of a disease? Could she be contageous? Or is it more likely a sign of old age giving her problems with eye site? Thanks to all the experts out there who answer this one!
