Its a domestic long hair - most cats don't fall into a specific breed, and reddish black fur is far more common than bluish black fur.

The best you can generally do with cats is look up their colouring/marking patterns to see if that has a name, but it doesn't really mean much breed-wise.

My childhood cat was a York chocolate. They are very vocal, quite smart (like can open doors smart), and extremely friendly, if mine was how they ordinarily are.

Standard cat.

That is a giant soot sprite.

Male most likely. He's very handsome.
