i just got a 2 year old female at over 4 foot and 2000g.i offered her first meal (with me) and offered a large adult rat but she refused to eat it.i know its probably just settling in but i wondered what size rats more experienced keepers on here would offer.the large adult rat seemed about the same size as the thickest part of her body.also how often should i offer after she refuses? i feed my babys once a week but i hear every 2 week is enough for an adult.im guessing shes a good eater because she is very big.
