3 Cats and 2 Mals We have three cats and both the malamutes. When we first brought Nanook home Kirby and Max backed Nanook into the corner. He was terrified of the cats. That of course is no longer the case. In Minneapolis, we had an invisible fence because I have a cat that loves the outdoors. Kirby worked very hard at teaching Nanook to case him. He would zoom in front of Nanook stop a few feet away and look at him turn around and run around the side of the house. Then you'd see Carboy's head peak around the corner to see if Nanook was chasing him. It was a really fun game until Nanook got faster than Kirby! Of course now we have a race course throughout our house. You'll see two cats and two dogs running up the stairs over the bed down the stairs around the living room and dining room into the kitchen and into the family room. It's great fun. It's even better if you can do it in front of Mom or Dad. It's really great if you can jump into Dad's lap!
