I know this is a common thread topic but I am not perfectly clear on why my bp's are so small. I have a male 1 1/2 year old ball python that is currently 320 grams and an unsexed bp that is 2 years old and about 465 grams. I feed them once weekly small rats. They both eat well. About 2 months ago, I switched from mice to rats in the hopes that this would help. Should I be feeding more frequently?
