I carefully sprayed every phone & electrical cord with Bitter Apple and that kept mine from biting them. You could also get some metal conduit ... it's used for outdoor lighting ... and they for *sure* couldn't bit through that. I would think anything plastic could be bitten through eventually. Maybe a combination of Bitter Apple and something like the cord cover ... --Barb-- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- -=- Barbara Carlson Carnegie Mellon University, Pittsburgh PA [Posted in FML issue 1480]
