My friend and I both have a black cat.
Actually I got a tuxedo kitty from her and she had a litter and now I have a solid black boy kitty. He is at least 3 yrs. old.
She names hers from Greek kitties.
One is named Bast.
Look up the Greek name of the worshiped kitty.
That plus others without any background I know.
Like Cleo (cleopatra) or Ceasar?
Mine is actually BB as in BB King or another meaning not appropriate to list on the forum.
