I was a philosophy major, and at one point was very good at philosophy, and took a class that dealt a lot with this problem. I forgot almost everything, but for some reason I feel inclined to talk about it. I learned almost nothing in the class, but this is what I ended up thinking.
My impression of all the things I read were that they very much followed the model of Peter Singer. Peter Singer argued very clearly and persuasively that if we are going to be consistent in our rational moral values we must extend rights to animals. This is basically the same thing that's being argued in this thread.
It usually goes something like this. You can start by asking yourself why it is that humans deserve rights. Then you make a list of them. If you take this list, you can notice one of two things. One thing is that the list probably contains a lot of characteristics that many other animals have in common with is. Other animals bond, feel pain, avoid suffering, etc. The other thing you'll notice is that even if certain humans don't have those characteristics, we usually still grant the rights to those humans. This is true even if that human has less of those characteristics than, say, a dog. Often people with brain damage or babies are given as examples of humans that don't necessarily have those characteristics, but we nevertheless grant rights to. Because of this, it's obvious that our morals are inconsistent. Whoever is writing will then go on to show that granting rights to animals will make our ethical standards more consistent.
This is all well and good, and it's very much in the vein of traditional western philosophy. You could imagine Kant drawing up similar ethical arguments, just not involving animals thanks to the period he lives in.
The problem, I think, is that rational moral values are an illusion. Even as stated above, we start out with assumptions about ethics. We say that humans have rights, based on no rationality whatsoever. Once we start thinking about this problem, then we make a list of reasons why humans have rights. Well, we didn't think of the list before we started, and yet we still thought it was wrong to kill humans. Obviously, the list has nothing to do with why we don't kill humans--otherwise our thought process would be moving in the opposite direction. So, why should we be basing whether or not we kill animals on this clearly artificial list?
I can't remember the name of the philosopher right now, but it's someone strongly influenced by the pragmatists. He basically said that ethical words are just ways to pass on cultural values just like any other words. When we say, "Eating animals is wrong," what we're really saying is "I don't think you should kill animals. I don't like when animals die." It's the same way that "Stealing is wrong" really just means "I don't want you to steal. I was taught as a child not to steal, and you could get and trouble and all that. I don't like stealing. You'll disgrace our family! (etc)"
You can build up rational arguments for your ethics, but at the end of the day I don't think it has anything to do with what is actually 'right' or 'wrong.' There's no way to determine whether an ethical argument is correct, or if it's better than another ethical argument that says the opposite thing. There is only rhetoric. Of course, you can make arguments that perfectly follow logic for both sides of the debate, but it will never mean anything because on both sides certain people will reject the premises. Even logical arguments come down to, "I don't think you should kill animals. I don't like when animals die." It's nothing more than that.
We can try to sound objective and be rational, but I don't think that's really what's going on. It's just tricks with language.
