I love the Persian breed. I've had two purebreds and they are wonderful. They are quiet and have more dog-like characteristics. Both would meet me at the door when I'd come home. One of them I'd put on a leash and take for walks in the neighborhood and people thought he was a dog by the way he behaved. While they take a bit more work to groom, they are very affectionate and worth the effort!
I now have a Burman/Japanese Bobtail and I don't think I'd get one again. They are very difficult to train and when you say no they do the exact opposite (always!) While we love our cat, we do get annoyed by her constant meowing which sounds like a whine. Live and learn :)
