Is it really normal for them to grow so much so fast? I figured it was going to take 2 or 3 years for my male bp to reach full grown. I dont know when he was born due to cirvumstances surrounding my adoption of him, but as of last week he is about 24 inches. (havent gotten a small scale yet to keep track of his weight either.)

so if my best guess is he was 3 to 5 months old when I got him, what is a normal size for that age? (I've had him since end of February)
