I wouldn't worry about the size. It's more of a length thing, and you have to trust me a little on this. Most people find that once they have raised and worked with their snake, it becomes much smaller. I remember thinking a 6 foot animal would be shockingly large. Now, I have 2 snakes approaching the 7 foot mark and I'm thinking they are somewhat smaller than I wanted them to turn out.
My coastal is still growing a bit, and I was hoping for a minimum of 9 feet. I can one hand handle her still.
In general carpet pythons are fairly light bodied snakes you should have no issues with that beauty, other than deal with my jealousy.
I like my girl, but if I new then what I know now, I'd have grabbed a Brisy!
