Boycat came and flung himself on my lap today. At some point I realised that on his (very floofy) fummy there was a teeny black slug. I may have shrieked a little bit, he deserted my lap at speed and when he finally stopped running, it was on our bed. When I rather cautiously approached his undercarriage, there was no slug. It doesn't seem to be on the duvet (at least I bloody hope not) but where is it?? And given the wet winter we're having and his tendency to roam outside in long grass, is this going to be an ongoing problem? Help!
