Does anyone know a figurative meaning for "Le chat bleu" -- ("the
blue cat" in French)? It was used in a comic strip in today's newspaper, and I googled around quite a bit and couldn't find anything. It seems as though it might mean "hangover," or "depression," or something like that.
Context; A man (whose wife is dying of cancer) goes to the kitchen during the night and pours himself a drink, presumably alcoholic. Someone, out of sight, says "So, skipping right past the hot chocolate these days?" In the next frame we see that the speaker is a cat, who then says, "Nothing for le chat bleu?"
I am totally mystified. This is usually a pretty straightforward comic strip.
