Wolverines have soft tummies too. That we see cats as cute is not so much that they have evolved to be cute. They look little different than wild cats. We see the palus cat as cute but pet its tummy and you will lose some organs. Those humans who protected and nutured cats were better survivors. Having cats around gave them an advantage over people who were indiferent to cats. We finding them cute is a trait that has evolved in us.
