Between comparing the two....
Carpets can be a bit more squirrelly. More prone to quicker movements and nippier. That's not to say they're evil or unhandeable, but they'll keep you on your toes more. They stay thinner than boas. A 6ft carpet sitting coiled in the cage will take up like less than a 1ft diameter circle of area. They look all cute and tiny. Then you go to get them out and they give you sass and you're like "whoaaaa there's a lot more of you than I thought!" haha. But they're definitely smaller overall.
Boas (BCI's) are calmer, get bigger (fatter), and are generally easier to handle. Their metabolisms are a bit slower than carpets too I believe.
I've worked with both, though I personally don't own either. Between the two, I like both. I'd like a BCI female just as a pet. Don't have any interest in breeding them really. I like the Moonglow morph, I think. I'm not great with keeping up on all the boa morphs tho.
I love carpets paint jobs, smaller size/body shape, and more feisty attitudes. Some carpets are definitely in my future. A pair of jungles for sure and maybe some coastal stuff too...![]()
