I am so sorry about your loss. Getting a snake from a pet store can be a very heartbreaking experience. You may want to get your next snake from a reputable breeder next time. There are a lot of good people out there that will sell you a very healthy and well started snake. Sadly, pet stores will give bad advice such as only feeding a baby snake once a month. A baby snake should be fed at least every 5-7 days. The above mentioned care sheet is a very good place to start for information.
