The boys have times where I would think they are fighting. But tails are up and both want back together if I separate them. They roll around and chase, snarl, growl, bite, ... but never to "pain". Neither of them yelps or anything like that. They do not cause each other any pain or bloody bites.
And then when Max runs to hide near me, Mickey will get a toy and tease him back to him by playig with it in his face and running. Stuff like that.
How can I tell if it is play or not?
Thanks
