That's great news! I know what it feels like when you really want a cat, and you finally get one. I just got Blueberry last August! I was really nervous too, about how to take care of him and all. But if you have any questions, ask the breeder. My breeder was very helpful. And also, post your questions here! We'll be glad to help you. I'm sure you and your family will love him, and he's be very happy living with you.
August 21 is a long time to go, and the waiting will seem very long. The day that I brought Blueberry home was very fun! I spent all day playing with him, and he adjusted nicely.
I'm sure you'll love your new cat!
