In this picture, she does not look too thin at all. Boas should be lean and muscular - they are not ball pythons and should not appear chunky. This female is really nice.
I am so sorry this happened. That's totally uncool.
You might get lucky at the next expo. Hypos are usually readily available and prices have come down over the last year. I bough my female hypo for $200 last May, but she is also double het for ghost which adds to the value. An exceptionally nice super hypo might also be worth 200, but I would not buy a super off craigslist. That's a lot like buying a het - there's no way to prove the super until its bred. Buy a super or a het from a reputable breeder with a good reputation.
Hang in there - hypos can be found pretty easily. I am sure you'll find the snake of your dreams with only a little patience.![]()
