Okay, so I have an 18 inch Ball Python that has been eating hoppers (I think? Maybe weanlings?) but I'm not sure if I should up his food size or not... Oh and I have no idea what to CALL each size of mice.

The mice he's been eating were about an inch/inch and a half long and looked like tiny little adult mice by the way that they had their fur all in... What stage would that be? I don't want to look like an idiot ording mice..... again.

...I just realized I must sound like such a newbie.... Oh well, I need to know it and there isn't a better place to find out!
