Looks like a Bombay. I have one but he's a 16 pound muscle bound hulk and stalks me. I'm simply not allowed to give other cats attention unless he supervises. I have to whisper to the other two or he comes and gives me the look of betrayal and I have to give him attention to boost his ego. Bombays are called "velcro cats" because they tend to attach to one especially. He also got separated from his mom too soon somehow so that doubles his stalking. A jet black void hulk cat in a dark hallway with one glowing eye around a corner is a tad spooky🤣
