They were eating small adults when I got them, and that was all that I could find to purchase, plus the female is considerably larger than the male. I thought that the mice seemed big too, but I felt that I had to try something. If the baby bps can go that long without feeding, then there is something else wrong with the male. Vet said it sounded like a bacterial infection in his digestive system, but needs a fecal sample to make sure. I found a local vet who wants me to bring him in, so he's off to the vet now. Hopefully things will be ok. Thanks for the input.
