We have a purebred Siamese with CH. AJ acts just like Bobbi. I'll find him in our den, running in circles. Or he gets "stuck" when he walks up to a wall and can't figure out how to get away from it. He's at his best, however, when he's romping with his buddy, Tiki (the Jack Russell from Hell(and, yes, he's named for Tiki Barber)). They chase each other through the house, falling all over themselves, gnawing on the other one's legs and ears, barking and mewing. OMG, it's a total kill!
