Max is
When I come home, he'll come up to me and rub himself on my leg like a cat does, with the head rubbing and all. We don't have cats, never did, but I do believe his breeder has one or two. Did he learn it from that young an age, or is this a rottie thing?
Also, he'll bat at a toy like a cat too. As he play bows, he'll bat, bat, bat, then pounce. It's really cute to see him.
