I think Cali has the potential to be a psycho-dog. She's never been caught with a knife but on occasion can become a bit of a whirling-dirvish. There was a time when Mikki would join in with the antics and they would entertain themselves for quite a while. But Mikki is not so interested in playing anymore. She just looks at Cali with bewilderment and a little fear. Eventually she sought refuge in my arms.
