I'll get the information out the way first of all. She'll be 2 in December, temperatures are usually steady 80-82 cool and 90 warm, using UTH and controlled by thermostat. Humidity can be a bit unsteady but always falls in between the 50-60% mark, substrate: aspen.

She hasn't eat in around 7-8 weeks, i know this isn't long compared to some but this is a hungry girl who would eat everyday if given the chance, so really unusual for her. We changed rat supplier recently which she eat two of then completely went off it, switched back and tried her again and still nothing. She's hungry, out roaming for food and wanting it, and just refuses to strike it. I've checked her over, no signs out mites, scale rot, respiratory infection and she seems completely fine. Is there anything else i could look for with her? I'm thinking about finding a supplier for chicks, but don't want to hesitate in getting her to a vet if there's a chance something could be wrong. I could be completely over reacting here but it just doesn't seem right that she's never refused a feeding since we got her as a baby.

Thanks
