Why is Scrapie called such?
Scrapie
The name scrapie is derived from one of the clinical signs of the condition, wherein affected animals will compulsively scrape off their fleeces against rocks, trees, or fences. The disease apparently causes an itching sensation in the animals. Other clinical signs include excessive lip smacking, altered gaits, and convulsive collapse.
Sparky
Sparky is a common nickname for people and animals. In the British Commonwealth, it can also be used to refer to an electrician.
