Quick question.
While reading this BBC story I was struck by the use of the term moggie. Am I interpreting it correctly?
Thank you,
Osiris
Moggy (pl: Moggies) is a colloquial affectionate term for cats.
Australians use it too 
Thank you.
Wow, something new every day.
I always assumed it was some sort of derivation of calling dogs mongrels, a moggie was a cat of no particular breed, but then noone calls their dog mongrel in that context.
Moggy is to cat as mutt is to dog, as far as I can tell.
Partridge’s A Dictionary of Historical Slang (Penguin, 1972) has the entry:
moggy. An untidily dressed woman: low: from ca. 1880; ob. (Also dial.) moggy, a calf, a cow. 2. A cat: Cockneys’ (and dial.): late C.19-20.
