I've seen this picture before and this is a Maine Coon cat. They get very large and they're called the gentle giants. They're personalities are very dog like.

The kitten in my signature picture is a flamepoint siamese mix and it will take about 2 years before all of his orange points come out completely. He's back with his foster mom due to ringworm but is doing well so I'll hopefully be able to bring him home in a month or so.
