Does the auto grabber work on cows?

Excuse me, I'm curious about something. The phrase "auto grabber" seems to be a tool or device of some sort, but I'm not entirely clear on its intended use. Could you clarify if this device is actually meant to be used on cows? It seems like an unusual application, and I'm wondering if there's some specific context or industry where this would be appropriate. Could you elaborate on how an auto grabber would work on cows, or if there's perhaps a misunderstanding in the question?
