For more feline desquamation alternatives, browse through variations of slang used in countries where English is spoken around the world. Some of my favorites are Irish, Scottish, Jamaican, Kiwi, Australian, South African, and New York English. (Yes, New York English deserves a separate listing.) If you really want be specific about a character’s background, consider idioms and slang distinct to a particular region within a country.
Bottom line for writers: fresh phrases or clichés, take your pick.
