I'm not a big proponent of animal rights.
Still, certain animals ARE sapient and there's no way around that.
If chimps are capable of symbolic communication with humans, are self-aware, and capable of using and making tools, it's obvious that they should be treated with at least a modicum of dignity more than a goldfish or a hamster.
I'm not speaking of prosecuting sharks, or of giving those animals full human rights. That would be asinine.
I'm speaking more along the lines of never torturing sapient animals, avoiding invasive testing on them, and generally leaving them free and alone instead of kept captive for show and entertainment if at all possible.
