Can't wait to see pictures of your new boa.
I have a lot of boa's. When I say a lot, I mean a lot. I have more boa's than balls. While my ball collection is moving up in numbers, that doesn't mean my boa collection numbers have stayed the same...lol
I have never been bit by a baby boa or struck at (not to say this will never happen though). However, I have a friend who had a litter of CA boa's and I will say, I had never heard a boa hiss until I visited them. I don't know much about the CA boa's as I don't have any but I have heard they can be very temperamental and have attitudes (obviously this isn't true of them all). People have stated that BCC's can be more temperamental than BCI's but I haven't really seen that either. I have one BCC that had an attitude (the rest don't have attitudes) but I truly believe it was a result from the shipping and he was an older snake. My largest boa is a BCC and she is the sweetest thing ever. Even when they are large.
Boa's are really a lot of fun. My BP's are curious but it takes them longer to start exploring. Some of my BP's will jump back into a ball when their heads touch anything and others jump a little. My boa's never really jump when their head touches something. I always fight my boa's to go back in their cages like other people have stated. Sometimes, this can be a hassle. Word of advice, get their head to touch the ground of the cage. Once their heads touch the ground, they will move forward instead of backwards to get out of the cage.
I have some boa's that will strike at the cage when you have food and some that will wait for you to leave the food on the newspaper and grab it when you leave the room. Each boa has a different personality just like BP's.
If you want a boa that doesn't get as large, stick to BCI and get a male. My older males are relatively large but they still don't eat XL rats. I only have one snake right now that eats XL rats and it really took her a long time to get to that point and she is my BCC. While the BCI's have the capability to get quite large also, the males usually stay smaller and you can feed them medium to large rats for most of their adult lives.
Good luck with purchasing your new boa.
