Something lurks behind the radiator.

And I thought it was the rat(s), who had a right old barny last night. As a sentimental animal loving veggie I feel uncertain as to what to do about them.
I don't mind rats but I am all too aware of the problems they cause.
I'll try asking them to leave, politely of course. If that doen't work well.....the Tajiki executioner might be visiting (Mary calls him in when I'm not around). She thinks I don't know.
