Raw intelligence isn't the only thing that drives our empathy toward animals though. I'd argue that it isn't even the main thing. We care much more about an animal's biological/genetic similarity to ourselves, which is why people are comfortable eating octopuses but not lemurs, even though octopuses are much better problem solvers and lemurs are relatively dumb. We also care more about sociability / the animal's ability to communicate with humans. This is why people are more comfortable eating pigs instead of dogs. Pigs might be smarter, but dogs are much better at communicating with us, eager to please, etc.
