After all 'cloud rat' sounds too much like a zoological rebranding exercise:
"Hmm the rat's been getting some pretty bad press ever since the great plague, we need to do something about that. I know let's just stick a pretty, fluffy word like 'cloud' in front of it's name. The public lap that kind of thing up"
But apparently the cloud rat does actually exist (although not very much) and it has a Latin name and everything (Crateromys heaneyi).
London Zoo's cloud rat is the first one to be bred outside the Philippines since the "squirrel-like animal" was discovered in the late 1980s and its hoped that more can now be produced in order to "establish a viable population outside the Philippines as an insurance population for the wild"
Not bad going is it? Discovered in the 80s, endangered in 2004. Us humans are getting really efficient at this extinction business.
