I enjoy playing with my Hermit crab. I used to have two but the scrappier one killed the other and took over his shell. Now tell me that is not cool. Cats and dogs may be territorial but damn. Drag you out of your house, kill you,and then have the balls to move in and live there . I love my hermit crab. His name is Buster. You know, Buster the body crab. coolest pet I've ever had.
