What size to feed?

[Vypyrz]

Yesterday we picked up a baby spider from an expo. The seller said she was 6 weeks old. I ask him what were they feeding her and he told me adult mice. I'm not sure about that. My Mojave and Normal have been eating hoppers and just starting them on weanlings. Also is there a thread with the different mice, rat sizes? I know you go by the girth size of the bellies but there are so many different mice and rat sizes

I generally use Rodent Pros website for sizes.

I mean small rats.

Small Rats normally start in size at around 48-50g. Applying the 10%-15% snake weight/prey weight formula, your snake should be somewhere between 350-400grams empty, before feeding small rats.
