I'd like to see a vote here, what percentage of HN readers believe animals have sentience or no sentience?

Clearly most animals are less educated, and most are less intelligent, but non-sentient? That sounds like 200-year old claims that "when one steps on the tail of a cat, it does indeed protest loudly, but not because it feels anything or because it would be sentient, no, no, it protests merely due to selective pressure, programming reflex circuits, since other creatures would show compassion, or back off due to a potential reaction by the cat."

Anyone who has had a pet like a cat or a dog knows they are sentient... if we consider ourselves sentient.
