One of our cats completely meets the breed standard for egyptian mau (in color, markings, body type, etc), has the same kind of meow, and the same personality that I've seen written about them on different websites, but I can't prove she's pure bred, as a former tenant at the house we used to rent left her there as a kitten (outside) and she decided to move in with us. Also as I understand it they're pretty rare, but I've seen a few at shelters.
That's about the only experience I have with them (other than reading a lot about them), but she does act slightly different than the average cat.
She chirps and wags her tail a lot, she also LOVES to play fetch with hairbands for treats, she's probably the fastest and most coordinated cat I've ever had (reminds me of a cheetah). She's very smart and can learn just about any trick (as long as there's treats involved, lol). She's kind of doglike actually.
On the down side, she's extremely possessive of any toys she considers hers, she steals all my hair bands and gets angry if anyone tries to take them away (she'll also hide them in places and go back later to get them). She's a bit moody also (but lots of cats are). She becomes fixated on things that interest her easily. Also because she's so athletic she can jump about 7 feet in the air straight up and get on stuff you don't want her on. This is stuff that doesn't bother me, but might bother someone else.
This all seems to be pretty standard in egyptian maus from what I've read.
Either way, she's a pretty cool cat
