Well, Arty does eat a lot. She eats up to four fuzzies a week which would cost £70 for a years food. When she reaches adult mouse size, I will feed her once a week which will cost about £30 a year so that will be good for my pocket.
I have just gotten 45 fuzzies and 45 hoppers through the post. By the time she has finished the fuzzies she should be more than big enough to tackle a couple of hoppers a week.
