Snakes (Or Rather A Python(s))
New tenant - been there a week, wakes to find a python behind the settee. We commission a biologist (we happened to know him) who identified it as a royal python. Only a baby (ahhh!!) not poisonous but will constrict, ie crush you to death when it grows up.
Previous tenant owned a three foot royal python which, of course, never left the cage and can lay up to fifty eggs each the size of a ping pong ball round the house - a striking coincidence.
Dave , I'm not asking for advice on snake control but who is liaible for the inevitable clean up? For the record, the previous tenants owe me £50 in arrears so the tenancy is still effectively live.
