She looks like our Leila!
You know, I think you're on the right track, she does resemble what I've read about the Egyptian Mau breed. I think our Leila fits that breed description to a tee, and she looks so much like your Snoopy, it's almost like they're relatives (Leila is 3 years old, and her ears are still very tall for her tiny body)! Take a look and see...I think b/c of her looks and b/c of her extremely active, athletic personality (when she's not sleeping, of course), she fits that breed description like Snoopy does.
