I think it entirely depends on what your next pussycat looks like.

It's no use calling it Smudge or Smokey or Ash if it's a ginger tiger. They're grey names.

We have a black cat named after a black bird (Raven) and a dark tabby called Shadow - when I rescued her, she followed me everywhere and you can't see her in the dark, like my shadow. I don't know what her name was previously but she's not answered to Shadow now for 17 years.
