Grisotto

Martinetti was so _sad_: his cat, Grisotto, an old grey cat, as he describes, meant the _world_ for him.

O. T. O. H., usually the wrong one, the French use the word to mean a female prostitute:

"The sexual connotations which had long accompanied the word 'grisette' are made explicit in Webster's Third New International Dictionary (1976) which lists one of its meanings as a woman who combines part-time prostitution with another occupation."

Some life!
