Cherry leaves are a pointed oval shape, those are heart-shaped leaves (bindweed sort of ones - very often used on glass, presumably because of their interesting shape).
I'm not very good at plants, I'm afraid, but we do have a few folk here who are.

Puss looks a lot more cheerful and a lot less sinister in your later image.
The surface inbetween the cat and the vegetation looks very like a corroso finish - that's a
very heavily acid treated way of doing things - but again, not an area I know much about at all.
I think we need more opinions!
