Thanks for the well wishes everyone
And I'll for sure have to check out that snake measuring tool.
I've been really fortunate with Garrus; he has never refused a meal, and has only nipped me once. I occasionally try to handle him when other people are over as well, just to build up his comfort around humans.
I've found it really helpful to think about my actions around him through
his eyes, so to speak. I can't really tell if he recognizes me, or if he's just become comfortable with a large, warm thing picking him up and bringing him food :P
