Taken George to 2 vets. One said fat stored in casque, the other vet said circulatory system problem. Does anyone have another opinion or agree? When vet said fat storage, I found all of George's mealworms in his substrate in the bottom of the cage. They had been crawling out of his dish! Can't remember how many grams he weighed, but no way it could be fat in his head. Now I hand feed him. Swelling has been going on since 08/15. Thanks.
