       | Thanks to evolution, mom cats are hormonally rewarded for taking
       | care of their kittens. When the kittens are nursing on mom, she
       | often looks totally blissed out like a raver in an ecstasy
       | puddle, eyes half-lidded, staring off into space, paws kneading
       | away at nothing.
       | 
       | I assume that kittens evolved to knead because it stimulates
       | milking and then cats just make that association with the act and
       | feeling good, so they retain it later in life.

         | 
         | We gave away all the puppies around the neighborhood. We took

         | I don't know about every cat I've ever had, but my youngest

         | comfortable, like how we fluff our pillows or smooth out our
         | bedspreads or whatever. She's making the spot hers.
         | 
         | I mean it is an action that can also deposit their scent, but

           | Interesting. I've never heard that explanation. It doesn't
           | line up with my experience either. In 2007 I took in a stray
           | cat I found wandering in a parking lot. She was pregnant and
           | gave birth to 5 kittens. She died a few years ago but I kept
           | her with her offspring for her whole life. Her descendants
           | knead as much as she did.

         | It may have a real function in other situations (milk
