There are many organization which offer kitten adoptions. There are kitten rescues, which take cats and kittens which would otherwise die from shelter euthanasia and abandonment and provide care for the until somebody adopts them. Then there are the usual pet shelters which offer all sorts of pets for adoption, and don't focus solely on kitten adoptions. The most important task these types of shelters do - beyond giving the kitten food and a place to stay - is to provide proper medical care to otherwise neglected animals.
The one benefit of getting a cat from such a shelter instead of buying one in a store is that you will make room at the shelter for another pet to be taken proper care of. Thus you will not only provide a good life to a happy kitten, but also help a second kitten in need. Since there are so many kittens available for so many different personal tastes, you should do proper research and really pick the one kitten you love for adoption. This way not only will you get your favourite kitten, but the kitten will be taken better care of. This is a win-win deal for all involved.
