Cats have 5 grasping appendages

I was watching my cat playing yesterday, and I have come to the conclusion that cats actually have 5 grasping appendage! She was holding a floor mat with her two back paws, a piece of string with one front paw, and another piece of string with the other front paw and her mouth.

From a New Scientist article published 15 December 2015 (emphasis mine): Alex, the African grey [parrot] trained and studied by Irene Pepperberg at Harvard University, learned 100 words and even made up some of his own, including “ban-erry” – he already knew banana and cherry, and seemed to reason that an apple was somewhere between the two. … Continue reading
