So I'm going to a reptile show tomorrow to pick up some more frozen feeder rats for Olivier, but I'm not sure whether or not I need to go bigger on size. She's about a year old, but I don't have a scale to weigh her.

For reference, she's been eating weaned rats since I picked her up 3 months ago. She's about 2 feet and a few inches now. Should I get her on small rats or stay on weaned rats through the winter? Thanks.
