I wonder just how much my girl should weigh for her age and size. She's between 1&2 years old and just under 4 feet long. I weighed her this morning and she was about 170 grams. Does that seem low? She's my first so I don't really have any comparison.

She eats like a champ. We feed her once a week and she takes f/t small rats, about 4 inches long, sans tail. She'll take 2 if we offer it. I don't want to over feed her but I feel she should weigh more.

Yes? No? Any opinions?
