It's very frustrating. I don't mind him not eating but I REALLY don't want to keep a live rat around the house for more than a day lol. I can't return it to the pet store so I'm not sure what to do about that. I may try killing this rat too and leave it in the enclosure over night. If that doesn't work I may try a mouse. If he doesn't eat that, at least I can feed the mouse to my corn snake. I had a ball python a while back I bought as a hatchling and he/she ate like a champ. Ate at EVERY offering, but unfortunate circumstances forced me to move and I couldn't take him with me. I gave him to a friend of my girlfriends and she said I could have him back when I got a place. Well when I went back to get him she told me she sold him because he tried to eat her new kitten.
