Zoe with and without a tail

This was really interesting to me, too. I was snapping some pictures of Zoe (without the flash again). Her eyes glow red if there's too much light. Not just a little red-eye, they look like Christmas tree lights.

Since her tail is in constant motion, in the second shot, if you didn't know better, you'd think she's tail-less. It's moving so fast it's not even in the shot.
