My snake is around 1500 grams. Maybe around 2 years old. She recently came off a very long feeding strike and I've been giving her bigger and bigger meals over the past few weeks and she is now feeding on 100 gram rats and has plumped up nicely. So how often should I be feeding her? Should it be every 7 days or is 10 better? I think the 100 grams rats are the biggest the pet store carries around here.
