Feeding different sized mice...

I just started feeding Slinky 2 mice (which are btw not adult sized, they're actually really small) since he was showing interest after his first feed.

I have a friend who is trying to get rid of 4 mice that he doesnt want anymore (who knows lol). He says these are even smaller than the mice i feed my snake, about half their size but I havent seen them just yet.

My question is, if they are half the size of his regular mouse, would it be ok to feed 3 or so? Or should I stick to just 2 regardless of their size?

Im sorry I don't have the mouse weights or anything for references.

Mice grow pretty quick. If you put them aside for a week or 2 and keep them fed they should get up to size in no time. Maybe you could feed 2 and keep the other too til next feeding. Its not going to hurt your BP to feed him a little less one week and it also wont hurt it to feed one more animal to get the same amount of food. Whatever you decide your BP will be ok.

How big is your bp? Mine gets 3 of the biggest mice I can get a week.
