Jen to tell you the truth .. I can't tell the difference, but from what you are saying, I think its fighting. They fight for up to 20 minutes straight sometimes .. and they both provoke each other. I watch them and they often stare at each other with their ears pinned back and tails swinging like mad, and lily lets out a little meow sometimes then one of them pounces on the other!

I guess I'm on my way to get a water squirter!
