Angelique Meunier, an Australian celebrity singer/dancer took the name of a cat for her stage name. She must have hijacked the name of a fairly rare purebred pedigree cat, the Havana Brown, which is the name of a chocolate coloured fine looking cat breed. The origin of the name is unclear. It does not refer to havana cigars but may refer to Swiss chocolate or a rabbit!
I don't know of any other celebrity who has taken the name of a cat! It is quite neat in one way but I guess only a few people know it is the name of a cat.
I am slightly peeved because when you Google "Havana Brown" you are presented with a pile of information about this female celebrity. You have to add "cat" to the search.
There are many examples of the names of wild cats being used by people. Tiger Woods, the golfer, is the standout example but many teams also use wild cat names such as "cougar" and "lion" etc.
It is a shame that none of this translates to better cat welfare.
