I have a female that is 1700g's and she wouldn't take F/T. After a month, I tried a live rat but she wouldn't eat. I contacted the breeder and he totally forgot to tell me that she was a mouse eater. So, I got a live mouse and still she won't eat. Its been 7 weeks now and she has lost around 60g or so. Everyone I have talked to says its nothing to worry about so I definetely wouldn't stress 10g......depending on if your BP's are babies or not. I am now going to wait 2-3 weeks before I even attempt to feed her again so hopefully she is good and hungry.
