Hi everyone! I'm new to here because I'm getting my first ball python in two days (should be about 80-100 grams). So my question is, how many mice should I buy at first? I'm buying from XYZ Reptiles and they told me they feed their baby bps hoppers and I'm going to buy from layne labs which lets u chose from quantities of 10, 25, 50, 100, 250, and so on. I don't want to buy 25 for $57 (thats with shipping) only for him to out grow that size in a week. But I also don't want to buy 10 for $49 and then have to reorder it because he still needs that size. So basically, what quantity of hoppers should I buy for my baby ball python?
