Well,
My little girl finally decided to feed for me

)
Even though she's captive-bred and has been used to taking frozen/thawed for her previous owner, she's been a real pain for me.
Today I went and got a small live mouse from the pet store as a last-ditch attempt. As soon as she saw it, she grabbed it.
I was interested to note that she did not constrict the mouse. She just held it with the head in her jaws until it stopped struggling, and then proceeded to swallow it.
Do Spilotes constrict?
Here's a pic.
