Via i dont know
This is so true for me and my sisters. <3
Sometimes I cry because Doctor Who
Sometimes I laugh because Doctor Who
Sometimes I angst because Doctor Who
Sometimes I dance because Doctor Who
Sometimes I think because Doctor Who
Sometimes I get confused because Doctor Who
Sometimes I sing because Doctor Who
Sometimes I make awesome friends because Doctor Who
Sometimes non-Whovians don’t understand me because Doctor Who
But always my life is better because Doctor Who

Cheetahs make a variety of vocalizations. Unlike big cats like lions, tigers, leopards, and jaguars, they can’t roar but instead can purr like housecats. This is because of the structure of their hyoid bone. Their purr shows a content mood but also can portray nervousness. A birdlike chirp is used by mothers and cubs to call each other. Mothers alternate this with an ‘ihn-ihn’ sound to call her young. This is the call the mother and the cub are making in the gif. Growling and hissing shows aggression and defense while bleating which is similar to meowing is a distress call. The male stutter call can actually trigger ovulation in the female which accounts for the erratic reproductive cycles. [x][x]
