Thing with cats is they arent likely to jump to your aid in battle or help you find that elusive treasure. Now if you want a companion that will turn tail at the first sign of trouble, lick its own ass and walk around aimlessly before relieving itself in the middle of someones flower bed then yeah cats may be a good idea. But seem as though you cant really train cats to do anything besides go to the toilet in a tray or have them following you around merely for food they would be pretty useless & yes I own cats.
