What is it about animals and cable chewing? You'd think the cables would taste bad to the animals or something. Do they think the cables have a hidden creamy nougat center?

Well, they clearly have a nice, chewy texture. And at least to rabbits, they look like roots - something you just have to chew on.

I have found that the rabbit brain is probably wired to divide the world into a few clear categories - "dangerous - run away", "edible - chew on it!" and "hmm... mate!"
