Say you found a baby animal, injured and traumatized from an attack. What will you do?

(a) Pick it up and try to nurse it back to health, despite poor knowledge of what to do
(b) Pick it up and, if its too badly injured, just provide a warm and safe environment so that it can die in a comfortable manner
(c) Ignore it and let nature go its course
(d) Pretend you didn't see it at all

No, this isn't a real quiz but it's something I had to face just now. My dad found my cats attacking a baby sparrow but when he shooed the cats away he realized that the bird was still breathing. We placed it into a box and tried to wrap it in a worn out cloth and lots of paper towels and force-fed it with milk. But we don't know if it would survive.

But really, which answer should be the correct one? Because really, each answer is perfectly logical. (a) is because you don't want to see a living creature die, (b) is because you know that there is no hope so the least you could do is to provide a safe and warm environment, (c) because you believe in nature's survival of the fittest theory, and (d) because, well, it could be both ways - either it is too painful to realize that an animal is dying before your eyes, or because you just don't give a damn.

Looks like my family falls under (a) and (b) when we see an animal which seems to be dying... But in actual fact, we don't know how to care for a baby sparrow. I went up the internet and the messages urged that one should feed the baby sparrow every hour or else it would die. So I am contemplating if I should really sacrifice my sleep for the sparrow by force feeding it with water every hour. Then again, if it dies in my hands how would I reconcile that fact?

It's just that heart for the poor creature that makes it so hard to imagine the worst... And even more so the dilemma among all of the above options. What should I do?
