Just wondering at the feed value ratio between mice and rats for a 14mth old RSP.. she's on adult mice right now and smashing them down happily. They seem to be a good size for her, though doesn't leave much bulge in the tummy. She weighs in at 170g. Is there any nutritional value in switching her to equivalent weight rats in the upcoming months.. I know rats have higher fat content.. is this beneficial for young growing snakes, or is it irrelevant and just stick to mice til she is way larger? Thanks.
