Hmm. Tough question. I would say that would depend on the circumstances. If the animal is in pain, and its life would be painful, I would say that it would not be humane to make it suffer for a little more time forus? Would it? However putting it down because you don't want it any-more, would be, in my opinion, murder. Animals aren't objects, they're living creatures, and they deserve the same right to life as us.
