ok, this exact thing happened to me this past year. my snake came out of brumation, din't breed, and then wouldn't eat for about 6 mo. first, i took her to the vet to check for parasites. everything came back normal, so i talked to a good friend of mine and he said to jack up the humidity and change the prey item. so i put a towel over the glass aquarium and put the humidity really high and fed her a chick instead of a rat. she ate. slowly over the next couple of months i weaned her back to half chicks and half rats and just a mist when she is fed.
