Are Persians loud snorers?

Hey a little help?

I got a new foster today, a little black persian named Diva. She is very cute, not purebred because her coats not as long, but still has an extreme face. She was returned to the rescue I foster for because she was having problems and the girl did not have time to work them out. I am happy she returned her to the rescue like she is supposed to, but think it's a bit strange she's a student, studying to be a vet!!! Anyways, is anyone familiar with this breed? She seems to be quite the loud breather, snoring while she is awake! Is this normal?

 

Could just be because of the deformed face, but it wouldn't be a bad idea to have the vet check her out for a respiratory infection or some other serious problem.

Two of my cats (Turkish van & British shorthair) snore really bad and often sound a bit weezy even when they're awake, but their problem is just allergies.
