I just purchased a male firebee born 4/19/15. He weighed in at 790 grams today. I have a book listing every feeding and his weight since he was born. In the past 3 months he has only been fed 5 times. How often should I feed him?

My female pastel born in 5/15 is only 300 grams and has been fed every 5-14 days with the great majority being 7-8 days. Should I up her feeding to every 5 days? She only has 3 weaned rats left and then she will be moving up to smalls. She's really girthy for her length.

Thanks,
Andrew
