one of my little guys has for 2 days had poops the size of grapes. not at all normal for what l usually pick up. no change in feed that l know the other little one is doing his business the same as always bigger and nicely formed as far as poop goes. could this be a sign of something wrong l don't recall ever in the past few years seeing any poops this small. maybe it is a lack of water perhaps though l do see him drink during the day. he is eating well running around clear eyed so no outside signs l can see but do worry it could lead to something l don't want.
