Cat wrestling ... do humans understand?

Dear George,
Nope! It's not what you think (looking at my picture with my brother).

I'd tell what it is - it is called CAT WRESTLING and I'm the champion in our house. It all started with my desire to help Stanley (my brother) to be more active.
Lately there was a lot of talk about lifestyle, healthy eating, being active - all this non-sense. If you think how much we helped humans to evolve over the years one might wonder if we didn't do ourselves a disservice. As soon as we trained them to be our humble servants they never stopped. They developed canned food, dry food, food in pouches, treats, frozen goods including farmed and frozen mice and all this in the name of their love for us! 

We marvel at all these packaged goods but in the meantime we became less and less active. Obesity runs rampant in North America for both cats and their humble servants. My brother is just an example; he's not obese yet but he's not active and he sleeps all day. So, I thought of something fun to entertain him and make him "move" around. That's how I started cat wrestling and I was quite successful until the day Mom caught me and started yelling to leave Stanley alone. She THINKS we are fighting. She said cat wrestling is absolutely forbidden in our house!
George, this is the reason I'm writing to you. Can she get me in trouble? It's just a game! Can she "make" cat wrestling illegal? I don't think she understands what "wrestling" is all about. What do you think?

Dear Rocky,

You are so right. Indoor living has a high risk of obesity. Lots of energetic games between loving siblings is just what is needed to keep healthy. So wrestling is great. But there is one worry. How does Stanley feel about this?  Is he enjoying it too?  Or does he feel bullied?

Humans are hopeless at working out whether wrestling is fighting or play fighting.  And it matters, because if it is fighting, not play, one of the cats will be feeling very unhappy. Are you biting him, Rocky? Is there fur, or even blood, on the carpet? If so he needs a new home.   

Is Stanley beginning to wear a cautious look? Is he being ambushed at the litter tray? Or frightened to go to the food bowl?  If the answer is "Yes" to this, then you are bullying him. He needs lots of hiding places, separate litterbox location and a separate food location.

On the other hand if Stanley starts a wrestling bout, if he plays an equal part in the game, if he is sometimes the winner, and if the play is reciprocal - then it is play. So wrestle on, my friend.

Love 

George.
