As a teen growing up I had a cat named DC. It stood for darn cat on good days and I leave to your imagination what it stood for on bad days. :lol:
Other names... Well you could call him Ten for the 10th month of the year, Tober for October. The show Cats has great names like Mr. Mistofolees (the magical mystical cat). Doom because you hope he will spell doom for the mice. Mousetrap is a cute name for a cat, maybe you could call him trapper for short.
Almost all my cats have nicknames to go with their regular names. The nicknames are usually a manifestation of their regular name. DH is a great one for nicknaming them and they always seem to stick because I start calling them that too. My one cat Rhumba, only answers to his nickname Dumpa. And my wegie woolybear answers better to woozpooz.
