I would say definite Persian as well. With or without papers, a Persian is a Persian, a Burmese is a Burmese and an Oriental is an Oriental
As CS has mentioned, her breed could distinguish her from another cat if found, if she was classed as a DLH and someone found her and handed her in, you would not be notified because they wouldn't be looking for a Persian. I really can't understand all this oh it's a moggy whatever without papers, I have a shepherd, if she had no papers, would she be classed as a mongrel
It doesn't matter at the end of the day if they don't have papers, it
does not turn them into a moggy overnight, and being honest, who gives a damn whether they have papers or not unless someone wants for breeding or showing etc, but I would say looking at her, she is a beautiful Persian girl
