Mouse fluffs are very small (too small for a Royal in my opinion). If it is a mouse I'd suggest moving up to a small mouse or Rat Pup next feed. If it was a Rat Fluff, then excellent work getting a nice big rat into him
i reckon Colin gave you a fluff he gave me one which was to small aswell if he gave you some bigger ones, offer her that in 5 days. Thats what i did for Drazen, i reckon he's a bit underweight i'm going to weigh him tomorrow. i'm going to offer him a mouse every 5 and try gtting him on rats.
