There are no shortage of Massacusetts shelters with kittens and cats looking for homes. Some will have all-black cats. You may have to settle for one a bit older than a kitten, especially at this time of year.
Try looking for organizations with "cat" in their name rather than "dog," Ask your vet for suggestions. Ask local pet stores; most no longer sell kittens but many have arrangements with local shelters. One of the churches in my area hosts a monthly cat adoption day. The MSPCA also has many cats looking for homes, mostly adults but occasionally kittens.
If you go out looking, rather than waiting for a cat to come to you, I think you'll find one you can't resist... black or not.
