quick question

[Nancy Palmer]

I know this is probably a gross and disgusting topic, but I just was curious
as to what you'd classify as diarrhea in gerbils?  and also, i've seen this
mentioned a few times and have no clue, but what is KMR?  Sorry for what is
probably two questions i should know the answer for, but i'm new to this
whole gerbil thing, and i'm just trying to become better informed.  thanks!
