Cass I have to disagree, I don't think that looks like a normal boa stool. It seems slimey and almost appears to have the shape of a rodent head in the area to the far left. I'm no expert on regurges please understand but I've cleaned up a far bit of boa poop with Rauri and none of them appeared like your picture.
Do you know when the snake for sure last ate before you transported it home? Does it have any history of regurging? I wish I could remember where I read that BCC's tend to regurge a bit more easily than BCI's but I will have a good search today and try to find reliable links on this.
I'm not saying it's a definite regurge, just that it appears to not be a typical defecation to my eyes. I hope those members with more BCC experience will chime in here as I don't wish to worry you unduly if I'm way off base here.
