I think few people could deny that animals can dream, or feel pain, or fear, or happiness, or change behavior in response to reward/punishment, or figure out how to use simple tools, or how to work together to hunt or find food, as all these things are trivially observable.

I don't think that animals have a higher-order awareness of these things in other creatures. A bird will eat an insect, or a cat will hunt and kill a bird without troubling itself over whether its prey is conscious. They just see it as food.

So maybe not so different from humans, after all!
