People's favourite Exotic pets

Recently I've taken a liking towards including as many exotic pets into my gangs as possible.

My Cawdor are filled with cheap rats that have a surprisingly good kill count.

My new Van Saar used a spider for the first time yesterday and managed to web a pricey Squat heavy stubber on a lucky 6 (who latter got captured by the same spider when he was bonked over the head)

Yes I know there are more efficient ways to spend your creds, but not many are as fun. On my paint table I've got some cyber mastiffs, the FW giant wasteland rats and plans for the BB gnome goose and Badger as well as afew servo skulls.

So which creatures do people enjoy adding to their gangs? Any cool names? My spider was called Gribble.
