I'd be really skeptical of that, until/unless it's replicated a few times. Dolphins, Whales, Some birds, Apes, and Elephants... that's all I'm aware of at least

I'd be really skeptical of that, until/unless it's replicated a few times. Dolphins, Whales, Some birds, Apes, and Elephants... that's all I'm aware of at least. To be fair though, it's not the be all end all of tests, and while passing has strong implications, failing shouldn't be taken as proof of a lack of sentience either.
