A field as broad as this one surely deserves its own thread. Just as its natural bedfellow, Fascinating Creatures - Squids, allows discussion of some similar species (i.e the octopus), so this thread should open its arms to anyone knitting for gerbils, mice, rats or even pigmy shrew.
I think it should also follow fascinating items of hamster wheel news like this snippet forecasting hamster-powered ipods, thanks to special hamster jackets (a future knitting pattern?).
Thread inspired by guest post here.
