Thanks for the heads up on the carpet, I haven't opened the box yet (Bradley is in his feeding tank, getting comfy so I can try to feed him... paper towel in that one), so I can take it back. He is 3 months, 44 grams. The last time he ate was 7/23, and he had a good poo 7/26. Also, if I leave the (dead) mouse in the tank with him, how long should I leave it before I consider it no good?
