This really isn't necessary. The snake is perfectly fine and has not been underfed. Feeding every 10 days now is fine. Boas grow slowly and at different rates. From what I can see from the pictures, this particular boa looks really good. She'll grow at her own rate and increase her size as she's meant to. Letting nature do its work and feeding appropriately from the get-go is the best thing we can do for her.
Edit: did I miss something? I thought this snake was approximately 1 year of age - not 2??? How old is she?
2nd Edit: I noted from her card that she is a June 2011 baby (approx). That would make her about 1 1/2 years old. She is small for her age, yes, but I still say she's perfectly fine. A 10 day schedule is best for her and will be for the next year or so. Remember, snakes don't operate on a time schedule in the wild. You'll get a feel for what's right for her as you go along - go with your gut as long as you don't feed too often.![]()
