Lemurs have limited communication skills including hand gestures, loud cries, and body language. Their is speculation in the scientific community that Lemur eye sight is poor due to the low lighting levels and dry conditions of their natural habitat.
This mischevious night time creature is known for it's creativity. It is not unusual to find a complete and unique re-arrangement of the environment in their wake, including but not limited to precariously stacked objects, scattered objects on the ground, and large objects shoved in small holes.
"Did you see what the lemurs did to this place?"
"Yeah, they crammed 15 in...that hole can only fit 10"
"I came in and the lemurs were actually still there, creating more mess. I had to shoo them so I could fix the place."
