Sorry to hear about that. I had a similar experience with a cat (not one of mine!). I was using Nordost speaker cables at the time, and he chewed them up completely. The single reason I will not use Nordost in my system.
Animal damage to system
After a hard day of work all I wanted to do was relax and watch a movie. I was 2 seconds into the movie and the protection circuit of the receiver activated. Come to find out that the cat had chewed all 3 of the front speaker cables, 1 phone line and 2 coax cables. What kind of damage have you experienced with animals and your system?
