I think Kassa should have an indoor name and an outdoor name. I'm thinking "Super-Chill" or maybe "The Big Easy" as his indoor name. For a high prey drive boy he is the calmest creature I have ever witnessed indoors. Kassa does not seem to let anything bother him. I can run the vacuum right under his feet while he is sleeping on the couch and he doesn't even look up. I mean why would he. There is no chance that the vacuum will give him a treat right. Kassa even knows to go to the couch when I'm cleaning because I need to move his bed. He can hear a container of yogurt or the fish oil capsule bottle open from any room in the house. He can even seem to identify if I'm opening the drawer with the treats in it vs any other drawer. Those are good reasons to look up or even displace himself from his current location. I don't want to give the impression that he is depressed of course. He seems quite cheerful actually. I think either he his just confident that I wouldn't allow anything to hurt him and he is completely safe OR confident that nothing in this universe could possibly hurt him because he is indestructible. He is only 4 after all :).
