Lauren Huston Haha there's lots of differences but they're subtle.

* He's much bigger than her (really only helpful if they're side by side).
* He has yellow eyes, she has green
* Her face is very round with big round eyes, his is longer with slanted eyes
* He has a white tip at the end of his tail (which is very swishy, and swishes on command)
* He has a small white stripe on his nose, she has a small patch of white on her forehead.
* In general her fur is darker, he has more brown in his.
* Her voice is a squeak (she's basically like a big kitten), he sounds like a cat.

Plus if I'm home she can usually be found on my lap or on the computer, he has his spots out on the balcony. :)
