I don't wanna take him out and stress him further, but he is definitely smaller then 3 inches. Do you think he would just stop eating all of a sudden because of his cage? It hasn't changed since I got him. If I get a critter keeper do you think moving him in there will stress him out even more? And what size critter keeper should I get? I'm sorry for all of the questions, I feel kind of guilty that I didn't keep him in a smaller cage in the first place :/
