this is a big topic but I thought we'd start with intelligence.
How smart do you think non-human animals are? (broad question, I know... just say anything relating to that) do you think animals can reason? plan ahead? do they have feelings like love, sadness, etc? how much do you think their lives are ruled by instinct?
this is mostly relating to the 3% of animals that have bones, but a small part is also about the 97% of all animals that are invertebrates.
