Well, there is definate risk to overfeeding any snake. However, a young snake such as yours, and with the metabolism that the asian rats exhibit, could feed every three days without any problems, but your going to be dealing with a very fast growing snake that'll eat you out of house and home! lol Don't be overly conscerned about your snake being hungry, realize that in nature a lot of snakes don't even eat once a week, but sometimes will come across rodent dents and gorge themselves to withstand the next time they find food, which could be days, weeks, or even a month later. I've always kept mine on weekly feedings and have never had any problems. What have you been feeding your 10 month old? By that age he/she should be consuming a larger sized fuzzy mouse with ease.
