I've had several torpedo switches expertly removed and lost from lamp standards, and also chewed ring main cable (which I'm going to place in conduit when I get spare tuits), but recently he's targetting plug tops.
Is PVC plastic their version of crack? He seems a bit mad on it, and also has eaten a few CD cases and CDs I'd kept after importing contents to our squeezebox server.
Happily, I do belive we have now squirrel proofed the garage, so this should hopefully be the last of it.
