Scottish fold stray?

[L. Wayne]

I am noticing that strays come and go from this stray and feral feline feeding and lodging place. Now, there is a black cat with rumpled ears who sits on my back outside porch, that is, when Otis is not around. This cat's ears are not completely folded over like a Scottish Fold, but neither are they straight up, like in a regular DSH cat. This black cat is still afraid of me, and I cannot get within 15 ft from it without it running off. I am wondering if this stray is part Scottish Fold, or if his ears, perhaps from a birth defect, are out of correct form?
