Life: Idiotropic

See.  If they can get along...

Don't worry.   They are just playing.  And the cat enjoys this.  In fact, half of the time, the cat starts this.

So the dog is genetically wired to want to eat the cat.  Her little brain waves are going "chase, attack, throw around like a chew toy."  But somewhere along the way, she stopped and though, "but the cat is not a horrible conversationalist and if I eat him, then I'll get fur stuck in my teeth and I really hate flossing."  And so, if even to prevent the pain of flossing, the dog decides to think another way.   She goes to have a chat with cat.

Cat's brain wants to arch his back, hiss menacingly, and run from dog.  But, he thinks a bit.  "I do lay around and do a lot of nothing and may be a bit of one on one will keep my muscles rippling more than my flabby belly."

So dog and cat converse and come up with this wrestling play plan that will lead outsiders to believe that they are ferociously fighting,  but to a trained eye, you can see that the claws and fangs don't actually penetrate.  They are Hollywood style superstars of play fighting.

They are the children that chase each other all around the house up on beds and down and make a ton of racket until I stand up and find them and shout as if they were young siblings, "Would you both please stop fighting and settle down!  Enough!!"
