Ragamuffin (meaning a scruffy child) is too lovely a word not to use, though, so if you do happen to have a child about the place then do encourage it to explore a few thickets, or roll about in the dust or mud a bit.
However, if you'd prefer a clean, cuddly ragamuffin then you can have one of those, too:
The ragamuffin cat is the result of high and dangerous passions amongst cat-breeders. The Ragdoll breed of cat was strictly controlled by its originator, and, partly as a result of this, Ragdoll cats came to be bred with other sorts of cat with the aim of producing a new breed as friendly as the Ragdoll. The ragamuffin cat came into being in the USA in the 1990s.
The 1980s had also seen the appearance of a new sort of raggamuffin, this time in the French Antilles. (No, raggamuffin really spelt like that in this case, with two gs.)
Raggamuffin music started when a musician called Kassav began using MIDI technology to record instrumental tracks. Wayne Smith's "Under Me Sleng Teng" was produced by King Jammy in 1985 on a Casio MT-40 synthesizer. It's generally recognized as the seminal ragga (which was short for raggamuffin) song.
