Do animals feel anger?

I was just thinking about this the other day and I decided to write out my thoughts. This is what I came up with:

As defined by dictionary.com, anger is “a strong feeling of displeasure and belligerence aroused by a wrong.”So it is an emotion that stems from the knowledge that something is not right; in which right is in accordance with what is good, proper, or just determined by the victim of the emotion.Therefore, in order for a being to feel anger, said being must be capable of understanding the complex idea of justice (or right and wrong.)Since animals are incapable of comprehending such an idea, they are also incapable of feeling an emotion that is a result of it.So to answer my own question; no, animals do not feel anger.

i watched an episode of hunter/hunted last night and they speculated that a water bufalo may have attacked a hunter that shot his brother the day before.  in a group of about 5 in the hunting party, the bull made a beeline to the guy and killed him. a similar attack happened a week or so later in the same area where it attacked a woman in the party who had shot and wounded the bufalo the day before. 

they also reported that scientists are now noticing that the bufalo are starting to seek out and attack lions, their main preditor.  it is a strategy to keep the lions at bay and out of the bufalo's territory.  so, were these bufalo mad or just applying the "kill the preditor before he kills you" strategy.  i think the scientists are leaning toward the latter for the same reasons you are.  but it is also possible that people just don't understand enough about animals yet to judge the level of emotional thought they have. 

there are also cases of animals being racists or sexists based on previous wrongs done to them by certain people.  so, is this some simple conditioned response or is it an emotional reaction?  i don't speak animal well enough to know. 

very true. i could very well be wrong and my statement is merely my own opinion, but i still stand by it. an animal being sexist or racist is just another survival mechanism. if they were abused by a human male, then more than likely they will stay away from human males. not because of anger or an annoyance for the way they look, but because of the simple recognition that human males are dangerous and should be avoided. it is an animals ability to recognize danger that enables them to survive on this world.

Punch a bear and you'll find out.

by all means stand by your opinion.  i don't even have an opionon to try to sway you towards.  my opinion is i don't know, but i think it is possible.  i just thought the bufalo killing hunters was interesting.  well, you know, in a psycholical way, not in a hunters deserve to die way. 

It probably depends on the animal. If I try to take the food bowl away from my dog, she will probably snarl because of her possesiveness (or greed) over her food. Eww maybe another question is do animals sin?

in order to sin there has to be a communal of morality.  some apes have been found to have what could be a sense of justice, perhaps.  i don't remember what brand of ape, but they saw a mother ape whose baby had died try to steal another mother's baby.  all of the other apes chased her down and took it back to the mother.  is that justice?  is that a sense of morality (kidnapping is wrong, bad ape)?  i am not sure you can really put it as survival of the fittest mentality since that would imply that the apes knew one mother was better than another.  if it is survival of the fittest, would there be cases where the best mother was allowed to kidnap a kid from another not so fit mother.  

it is hard to look at these things objectively.  some people naturally ascribe human emotions to animals while others know that animals have no soul.  i think it is probably somewhere in the middle.  until we teach those buggers to talk i don't think we will ever "know". 

Animals have no anger? Slap a steer on the rear and test your theory.

aggression and fear should not be mistaken for anger.

I know some squirrels that are quite pissed off at Reb.

edit: I'm sorry, National Master Reb

I guess animal is a pretty broad word some monkeys and gorillas have their own set of rules for what is right and wrong in the group and I guess because they are not fare from being human they can feel anger and they are still animals.
