She Is a yearling and they can be very frustrating. First off I don't think you have too terribly much to worry about she is feeding just sporadically. You have a scale and the thing to look for its lots of weight quickly. I've seen yearlings that will feed weekly and then one day adjust their own schedule. Especially the girls. Second I'm not a big fan of dangling the rat to close to them. I drag it most of the time or to entice them I'll hold it about 6 inches away from them and shake it vigorously. Seems to work pretty well with out getting right in their face. I'm not to sure what the weather is around there also but some balls will go through their fasting stages and especially girls again will practice this. They will fast or eat very small amounts for a few months when their brain says hey it's time to brumate. Hopefully I didn't forget anything. But I hope it at least gives you a little peace of mind.
