Never hesitate to adopt a black cat! They are the least adopted color of cats due to a stupid superstition. I miss my black kitties. Maybe one day I'll find another sweet black kitten to adopt and join our other fur babies.
This looks like a Blue Russian. I had one about a hundred years ago. he would demand that you pet him, but only three times! then he would grab your hand in his teeth and hold it there before he got up and left.
