Sorry this is sooooooo long.
Crazy Deb,
Everything Linds mentioned is correct. Those are good guidelines regarding feeding for captive boas. Personally, I think it is based on a 'better-safe-than-sorry' rationale. Girth-sized meals allow a little more leeway for simple (and most often minor) husbandry mistakes. One large (not 3x or more bigger than the snake!) meal is more likely regurgitated due to suboptimal temps/humidity, bad water/dehyradtion, and probably most likely, premature handling. Not to mention serious causes such as parasites or disease.
Though I have had a boa regurge due to overfeeding once. I apprehensively offered a second rat to a boa that previously was only fed one (of that size). I, like yourself, didn't want the perfectly good rat to go to waste and he basically inhaled the first one so I gave it to him. Right afterwards, he didn't seem that bloated so I wasn't too worried. However, the next morning, my apprehension came right back. (Many hours later, sometimes a whole day, boas tend to swell up from their last meal. I heard it's because of the gases released inside the rat once the outer body is digested.) Anyway, when I saw how fat he was, I was concerned. Needless to say, two days later (3 since the feeding) he regurged. And I was 'lucky' enough to witness the entire event. lol
Keep in mind, I DO feed my boas 'larger-than-girth' meals so I am in no way suggesting that it is wrong. That's not entirely why I brought up the whole regurge story. Just trying to make you aware that boas WILL eat more than they can handle! Their eyes definitely can be larger than their stomachs.
I did learn my boa's limitations that night and haven't had a regurge from him since. Also, since I feed 'larger than generally advised' meals, I only feed my boas twice a week (at the most). I basically just feed them as soon as their girth gets back to normal (and usually a few days after that {not for any specific reason, sometimes just plain 'ol laziness :joker: }). It's also good to let them cruise around for food to get some exercise.
I hope everything works out and if so, you'll know what your baby can safely handle. Good luck! :thumbsup:
Thanks for enduring this LONG post.

To be honest, part of the reason I feed large prey is because:
Before I started ordering f/t, I used to kill the rats myself. I HATED doing this so I wanted to minimize the frequency while keeping my boa's well-fed. Yeah, I know...it's pretty selfish! :devil:
