About a hundred years ago Persians didn't have those flat faces...they more looked like the Turkish Van cat...a delicate long haired cat with a beautiful small face...but breeders have created that new "Persian" over the years, because a flat face looks more baby-like...

Maybe if your cat is a Persian mix it shows the original gene potential which I am sure lies dormant in each of today's Persians as well...however your cat is beautiful and loved and that's the most important thing!!!
