First -to BP.Net
Second - We need more info bud,
- How old is she approximately
- How wide is she? and do you know how much she weights in grams? (Most people use kitchen scales, and also feedings are recommended to be 15 - 20% of the snakes weight, and also the prey should be about the size of the widest part of your snake)
- I.E. I have a 150 gram BP and I feed her small mice which are about 22-25 grams every five days, i was doing 15 gram hoppers every three days but im cutting back)
