mouse/rat equivalent

[MarkyMcFly]

So, I've got a random unspecific question that's going to be tough to answer lol

Here's the deal, I've got 5 balls. (cue 13 y/o me laughter) They are all juvies, not too old, born around June I believe.

At my local petstore, the feeder sizes pretty much go pinky mouse, hopper mouse, regular mouse and large mouse. There may be something in between there, but the top two are Regular and then Large.

So, assuming you may have an idea of what these size mice may be...all five of my snakes have been pounding the regulars for a month and half or so of feedings.

So if you do have any clue what this "regular mouse" size is...do any of you know what size rat I should feed if i'm going to try to change them over? I'm assuming fuzzy rat or something, but i'd rather have an opinion from you guys.

This whole thing is very vague I know, as I don't have weights on my snakes or the mice i've been feeding them...but if any of you do have some advice, please share!!

Thank you!!!
