You guys are going to laugh, but I named my cat after our resident shivan Carl.
See, we've got some woods behind our house and we've been adopting cats out of it forever. You laugh but it's true, we've never been to a shelter to look for a cat. A couple of time for a dog, but never for a cat. Anyways, this monster of a cat came out of the woods one day and just proceded to setup shop like he'd lived there his entire life. I named him after Carl because when he came out of the woods he looked vaguely like a Shivan. It's weird, he's been de-clawed on the front and neutered. He's the most affectionate tom I've ever seen. I'll post a picture when I can get one.
