|Notable owners:||Magnus Bane|
The Great Catsby is the name of Magnus Bane's gray cat in the 1990s.
By 1993, The Great Catsby was 'getting on in years'. Jocelyn Morgenstern came to Magnus with her daughter, Clary, who pulled on the cat's tail. The annoyed cat scratched her, prompting the toddler to scream in a manner which caused Magnus to ask if she were part banshee.
- His name is a spoof of the novel The Great Gatsby.
