Latte is nine years old and has always done this. She sounds like a goose honking! It's really creepy and I know what you mean-it sounds like she's going to drop dead right in front of me. But she's always been fine! I read an article about it once and they suggested that you gently put your hand on her nose and this makes her swallow, which will sometimes stop it. These little princesses are so high-maintenance!! But, adorable!
