Dusty's nickname was 'Musty Dusty' - my mom started calling her that because it rhymed, and eventually she'd answer to it. Course she would stick her head into all kinds of cobweby musty places hence her name Dusty because of the cobwebs she'd get on her whiskers.

Jack (who's full name is actually Jack Frost) his nickname is 'Jack Sprat Could Eat No Fat' - We started calling him that when he showed up because he was so painfully anorexic thin that you could see his hip and rib bones. We fed him alot and he ate like a pig but his weight gain seemed slow in comparison. He finally fattened up and filled out in about 8-10 months of good care.

Bear's nickname is 'Bearsie Wearsie' - my mom came up with it and he answers to it now no particular reason except in rhymes.

Pooky has several nicknames:
'Pokey Pooky' - because he likes to poke at things including his brother Bear.
'Pookster' - because he runs around like a race car driver.
'Pookus' - just sounds cute
Also when he's really playful and gets the crazy kitty syndrome we call it 'Pookitis'. ROFL

Cami (who's full name is Cami-flage) her nicknames are 'Cami Kitty' or 'Wild Child'.

Sabrina (who was named after the TV show Sabrina the Teenage Witch which I thought was appropriate for a tortie) her nickname is 'Witchy'. Mom gave her that nickname after Sabrina bit her while playing.

Sassy's nicknames are: 'Sassy Girl', and 'Muffit' (shortened version of little miss muffit)

Josh's nickname is 'Motorboat' because he's always talking in some way with little muffled meows or sounds that come out like 'mmuurrroouu'.
