if one were going to attribute such behavior to animal instincts is it wrong to put humans in that same category ? we may be just a little more elaborate.
I like to think it might be the other way round. Like the smaller pieces of a hologram still contain the whole image, just less clearly, animals might share what we call consciousness, just less clearly. And that could be what "allows" them to feel (I guess that much can be said without anthropomorphising, that at least some animals show signs of emotions). That doesn't mean that we have to be the ultimate expression of consciousness, though.
Reading over my last post about magpies, I just thought of a magpie experience I had - or rather my cat Lucky had - that seemed right out of Hitchcock's The Birds. I was taking a walk along some fields behind our house, and as my cat sometimes seems to think he's a dog, he's following me at some distance, say, 100 metres. All of a sudden, five magpies take off from a nearby tree, circle for a bit and then, three of them touch down right in front of the cat. I'm thinking one of them's gonna become cat lunch, but instead I'm quite baffled to see that my cat obviously turns to run for safety. That same moment, the remaining two magpies land right in his way, quite obviously to cut him off. Looked absolutely planned or pre-meditated. They now surrounded and faced him and although their behaviour seemed casual, to me there was a distinct feel of willfulness. They definitely were up to no good.
And obviously, that wasn't the first time my cat had been harrassed by that "magpie gang", because instead of attacking one of them or trying to make it through the "enemy lines", he immediately cowers down, body as flat as possible, forepaws shielding his head. And he's not at all a small and vulnerable kitten. Wish I'd had a cellphone camera, it still totally baffles me. At least, that explained some of the scars I'd found on him earlier, which looked a lot like beak marks. And so I had to come to his rescue. The birds reluctantly took off when I approached.
