Spider Cat was a minature cat experiment gone wrong. The designer was meant to create a little pocket sized cat for lonely people who couldn't have a life sized cat in their flat. There was a malfunction and the end product resulted in three tiny cats being welded together. The designer, disgusted at what he had created threw the cats away and thought nothing more of the experiment.
The little cats found refuge in the insect kingdom, they named themselves spidercat as a way of fitting in the the bug community. They became a local hero, always flying to rescue an insect in need on their trusty magic butterfly.
