RE: What interesting things has your cat destroyed
I must be pretty lucky, because I don't have a whole lot of items my cat has destroyed on me! The only things that my cat really goes after are strings and cords. I need to be very careful with my chargers, because she's bitten into several of them and I've gone through at least 8 replacement cords because of her. My Beats headphones came with a really sturdy cord, but she got at it when I wasn't looking and bit right through it. I have gotten replacement cords for it but they were all thinner, and she got at those easily enough. I'm worried she's going to electrocute herself doing that someday, but she doesn't go after cords that are plugged in to the wall, only ones plugged into the computer. I can't leave anything dangling off my desk especially or she sees that as easy prey.
There was also a time when I was looking after my friend's kitten for a few days, and she clawed my bedding up. I ended up having to get rid of that quilt because she had shredded so much. She was just a kitten though, so I didn't really mind that much.
