I've had my common boa for a year or so. It was given to me because someone needed to get rid of it ASAP. I've very rarely handled it but feed it regularly.
The other day when I had the boa in a temporary container while cleaning it's cage I was just stroking it lightly because it has never seemed to enjoy ANY contact. I was petting it's tail and it jerked away quickly and I continued to lightly touch the tail and the weirdest thing happened. The 5 1/2 ft. snake gapped it's mouth open and made a very distinct, loud hissing sound.
This really freaked me out and I obviously stopped touching the snake. I've owned many reptiles over the years and I've never seen a snake exhibit this behavior, only monitors.
Has anyone else noticed their snake do this?



With more handling, usually they will calm down. Now, I have noticed that - unless your boa is used to being handled - they are a little touchy about the tail area. But, don't be alarmed, it's just a warning hiss.
