my kittens are 6 weeks old now (I turn around and they're all grown up!!) and tey have discovered electricity. They love to chew on the wires behind our couch. when we notice, we pull them off, and they will go right back. after taking them away about 4 times, they stop...and head straight for the back of the couch. I think they figure that, hey! if they can't electrocute themselves, they may as well destroy our furniture. how can I stop them from chewing the wires and clawing the couch? we have a scratching post, and they use it, but they use the couch, too. help!
