I guess in Grok's era, the line between pet and food was blurred, but at what point in civilization did Grok (if at all), have a "pet?" Were food resources so scarce that anything that ate something that Grok could have eaten not long for the world?

The reason I ask is because I find the studies about pets and blood pressure interesting. Relaxing with a pet seems very primal, but then again, I have enough other food options.
