@Don: Yes, I am feeding all my baby BPs with hopper mice.I live in the Philippines and the room that they're in are quite warm all day. I just expose her tub to a heating lamp for a few hours every morning to make her space warmer than the rest as she settles in, as well as for the water to evaporate faster inside. I was suspecting she's on pre-shed.
@Osk: Yup, she was underweight when I got her from the breeder. Only 79g at 3 months.I will try to make sure to have her feeding steady to gain her correct weight as soon as possible.
