Welcome to BPNet! We are becoming a very international site and it's wonderful to have you join our site.

One of the handiest tools when you are raising a snake is a digital scale so you can monitor weight gain. That's really one of the best indicators of how things are going. Over here in the States we generally either purchase small postal or kitchen scales (digital is best) and they aren't usually very expensive at all.

Remember your little snake is quite young and has made a major adjustment into your home recently. For these shy snakes this can cause some major stress and it's not uncommon for that to be expressed as a refusal to eat. I'd suggest you check out our BP Caresheet here to check that your housing for her is correct and I wouldn't handle her at all right now (other than for cleaning her home) until she's eaten at least 3 or 4 times for you. You should be offering her an appropriate prey item every 5 to 7 days at this point. If her home is in a busy area of your house, you might consider moving her to a quiet room where she isn't exposed to a lot of people moving around.

She's eaten for you and she will again. Just be calm, do your reading here, ask questions and take it step by step. These snakes are very hardy and if given the right care generally do just fine. Remember it's not like someone runs around in the wild dropping them prey every "x" number of days. As ambush predators nature did design to go awhile between meals. It's best if you can get her on a regular feeding schedule though so just work the problem and in no time you'll likely have a happy, eating well snake.
