What is a dog doing on the ‘Cats! Cats! Cats!’ web site? Tucker holds a place of honor on this site because he is the ‘Commander of the Cats’. Tucker breaks up cat fights, sometimes just before they start. He knows which cats hate each other and he barks frantically if he sees two enemies starting to approach each other. He alerts me to cat fights going on outside, so I can go out and stop them. No one ever taught Tucker this job or tried to get him to do it. He came up with this idea all on his own, and has made himself indispensible.
