My new boy did the same thing, the first rat I tried to feed him, him and the mouse also cuddled up. He looks kind of similar to yours now maybe a lil thicker and longer, anyways, It took him 4 weeks to eat anything. His first meal was last Friday. Thats when he finally ate. Yours looks fine to me, they are very instinctual animals. When they are hungry they will def. eat. Keep trying and I hope she starts feeding better for ya!
