My family walks every day through our neighborhood and pet other people's cats and dogs and feed them with treats 🙂

Agree that it is not efficient. But the Sparta used to have two kings: one to rule the kingdom, another to lead army in the war 😉
BTW: I can bet Elon would not touch military & space budget nor subsidies for EVs 😜

That's Idun

Somehow she will catch the mouse. Our cat Idun use to catch a bird and eat it and leave only bill and feet in front of the patio door. Or, if it is a mouse, just the feet (or part of gut) and the tip of a nose. So, no cat is perfect 😉
