Sure, I agree. 'Probably' is a much better word than 'must'; I'd go as far as 'very probably'. But I'd take issue with the 'we' bit - different people may experience emotions quite differently, and some may not experience some that are considered normal.
> See, that's my point. It wasn't always thus - in fact, not so long ago, we didn't recognise suffering in animals as such. It was only through work that evidenced such suffering that we came to our current understanding. And, err, perhaps really promoted anthropomorphism as a standpoint along the way.
I think you're probably referring to the body of recorded science when you say 'we', here - is that right? It can take a lot of work to prove something that seems obvious in the first place (and still worth doing, as obvious doesn't always mean correct, of course.)
I see no evidence that people haven't always cared for other animals some of the time - and some evidence that other animals also do, sometimes. I don't think this is new - it's just sympathy and empathy, which seem likely to be 'tools' used by social animals in general, to help them get on (note - I'm not saying 'MUST'!)
The giraffes certainly seem to be exhibiting sympathy for their dying keeper. Whether they're empathising is a harder, and more interesting question, and probably more on-topic.
As an aside, you playfully suggest cats are like people with Asperger's.
Asperger's makes it harder to empathise with neurotypical humans (probably because they're significantly different, so harder to relate to). It doesn't stop someone caring, or start disemboweling, ripping heads off and eating faces. Cat's aren't aspies, they're sociopaths. (Though probably neither, really - that's anthropomorphising again!)
