"Of course they should have," says Judge Lee, "But since they didn't, I think we ought to return to the dictionary definition: 'an animal that is tamed or domesticated and kept as a companion or treated with fondness'. How much of that applies to Siggy?"

• Siggy is not an animal, but seems to be domesticated and kept with fondness. I would argue that 2 out of 3 means Siggy is a pet.
