I agree with Angie. Cats are great pets, equally as loving as a dog and more self sufficient. I have both cats and dogs and the cats are way easier.
Oh and my son's first real pet was a cat when he was 5. He is 21 now and she is 16 and they are still a great pair. He is her boy and she absolutely adores him. When he comes home she goes right to the door like a dog and loves on him.
