UPDATE: The poor thing was not in fact dead. Went to get it on a shovel to chuck over the fence and its tongue darted out. Managed to get it on the shovel and very carefully took it to a hedgerow down the road. It slithered off on its own. Thanks everyone for the advice!
Exactly what it sounds like. Our neighbour’s cat has left us a lovely gift on the patio. Not sure of the best way to dispose of it, being a snake. Or if UK conservation rules dictate that we need to contact a wildlife authority? Anyone know? Google has been unhelpful
