Gordo spent most of his time at the lab. Not inside, of course, because they tried to keep it as sterile as possible; but he would lay himself in the sun at the bottom of the steps and everyone coming or going would pause to pet him.
We didn’t start thinking of him as a lab assistant until he showed up one morning with a local animal we’d never seen before dangling from his teeth. He dropped his offering at the foot of the steps. We gave him catnip as a reward; he brings us new fauna a lot now.
