Rescued undersized dumerils boa
 

I recently rescued a ~6yr old female Dumerils Boa (my second Dumi). With the exception of a bad case of mites, she checked out perfectly at the vet. However, I'm concerned she is small for her age. Given her conditions with the previous owner, it's safe to assume she was underfed. She's mellow, seeks attention, and eats like a champ. I'm curious as to whether there's still a chance for her to attain some decent size with a more consistent feeding schedule?

Yes, snakes do grow into their genetic size eventually. I wouldn't push food on her in an effort to catch her up to where you think she should be, just feed her normally for her age and current size.
