Funny you should mention it...
I just returned from my 'whirlwind cat tour' of the mid west.

I saw my mother-in-law's two calicos. Very petite. I saw my 'mom's' two rescues. Punkin' is a big all orange girly.
I saw my friend's two Ocicats. They need tummy tucks.
And I saw that Aby. Very sleek.
Plus, I went to the cat show and saw every shape and size in between.

What is my conclusion...

When I got home to Snowy and Mr. Jones. They looked HUGE!

Snowy is just a massive Siamese boy. He looks like an athlete.
