Yeah, the CERN talk* [0] coined the term Pets vs. Cattle analogy, and it was way before VMs were cheap on bare metal. I think the word just evolved as the idea got rooted in the community.
We use the same analogy for the last 20 years or so. Provisioning 150 cattle servers take 15 minutes or so, and we can provision a pet in a couple of hours, at most.
*: Engine Yard post notes that Microsoft's Bill Baker used the term earlier, though CERN's date (2012) checks out with our effort timeline and how we got started.
