Could my cat be mixed with a Devon Rex breed?

Your cat is adorable, but could be mixed with just about anything. She looks nothing like a Devon Rex. I have a cat that has a lot of the same behaviors as yours and he looks nothing like your cat. The only way to tell breed is if the cat has papers from the breeder or you have the vet do a DNA test. But really what's the point? It won't change anything - especially how much you love your cat.
