The sheep only thinks of his safety, and grass, so a lion shouldn’t lose sleep over its opinion, unless that grass is in the lions dominion. 
Unless that grass was meant to fatten the gazelle, the lion had been eyeing, unless that grass made the bed in which the lion had been lying. 
The tired lion that courts discomfort, broods over food, in the abundant jungle, remains wakeful, counting sheep to fall asleep .
