"The woman who was saving iguanas opened the cage of the newe..." — Ellen Bass quote meaning

The woman who was saving iguanas opened the cage of the newest arrival and asked if I wanted to hold him. She showed me how to slip my forearm under his scaly belly and bring him to my chest, not unlike soothing a colicky baby, though the iguana showed no distress and breathed evenly against my body, not cold, not warm, as if he didn’t mind being suspended in a stranger’s arms, as if nothing could surprise him in the tumble of the world he’d been swept up into. The iguana was strapped into a thin black harness that made him look like a leatherman from the Castro, an old queer with spiked hair and his wrinkled dewlap. I’d had a bad day, well really a bad year, and the one before that wasn’t good either. My child wasn’t talking to me and I’d stopped talking to everyone else. The iguana was still as a monk in prayer, all that moved were his ruched eyelids which opened and closed over his orange eyes. His chest filled and emptied with the dry hot air we shared. I thought to myself, even this is something.
