Hi! I am about to get my first snake, a female BEL (Butter x Mojave).. just waiting on good weather to ship. I am in the process of setting everything up - 6qt tub, Ultratherm UTH, 2 AcuRite Temp/Hygros, JumpStart Thermostat, 2 Reptile Basic small hides, water dish. Will be working on the temps/humidity so everything is good to go before she arrives. I have a quick question though. She is currently eating F/T Mice. I want to order some so I have on hand before/near when she's arriving. Most of the quantities I see are 50 for small mice and 25 for adult mice. She's between 100-200 grams. Would ordering 50 small mice be way too much. How quickly will she need to upsize prey? Any suggestions on sizing/quantities I should order? I've seen some sites where you can order smaller quantities, but I feel like for the shipping cost, it's almost better to order more, just don't want to have way too many frozen mice that will never be used. Hoping to eventually switch over to F/T rats.

Thanks!
