Poor Moose! With a change in eye color I'd be worried there was an injury to the eye, infection, or something such as a cataract in old age. If she's not eating she may not be feeling well which can also be a sign of this. It would be best to bring her to your vet to have the eye examined in person, and any treatment given as needed such as antibiotics. Until you can get to your vet, keeping Moose warm and eating and drinking as much as possible, as well as keeping the eye clear and clean (if there is any discharge) may help.
