Folks, keep in mind that snakes do swell up remarkably after consuming a large meal - there's a lot going on in the gut digestion-wise at this point, and it can make a snake very bloated & gassy...I doubt what you're seeing in that pic is *all* prey, but probably a combination of prey + "digestive atmosphere" going on. We've fed substantial prey items to some our big retics, and they swell CONSIDERABLY after eating a large meal, giving the appearance of having consumed an item larger than what was really fed. This is where the discernment part comes in - it is critical to monitor temps & correct environmental factors when you do feed a snake a meal of this size...if your temps are off, you're inviting problems.
I love me some Kara! =) This confirms what I've seen with my burm as I could have sworn his tummy lump was bigger the day after I fed him once.
Thanks to those more experienced for sharing information to newbs like me! I lub my $100/ft snakelette! (And he'd like his bun-bun now as today is feeding day, hehe!)
