Been wondering why people like to take pictures of cats, especially those testing out a new camera. It's not just here on Clubsnap, but also on dpreview and many other forums. Here are a few reasons I've come up with. Feel free to add more.
1. They're good looking.
2. The whiskers provide great contrast lines for getting autofocus spot-on. You simply can't take an out-of-focus picture of a cat.
3. They don't move much, so you never worry about motion blur.
4. They're patient subjects, just sitting or standing there gazing placidly at you.
5. They're everywhere and you don't need them to sign a model release.
