It really shouldn't have any because I haven't used it often til recently - and that's usually on the couch, no food near it. I reckon it was the open bag of biscuits and being placed near the front door that attracted the damn things (thanks heaps, Scott ) (yes, I'm blaming him, because it's all his fault )

Right now it's sitting in the garage, with a new deep scratch on it from the stupid vacuum. I'm in such a grumpy mood about it, stomping around the house swearing under my breath. I reckon I'll scare the things away
