The ability to experience pain in an animal, or another human for that matter, cannot be determined directly but it may be inferred through analogous physiological and behavioral reactions.[15] Although many animals share similar mechanisms of pain detection to those of humans, have similar areas of the brain involved in processing pain, and show similar pain behaviours, it is notoriously difficult to assess how animals actually experience pain.[16]
Nociception
Nociceptive nerves, which preferentially detect (potential) injury-causing stimuli, have been identified in a variety of animals, including invertebrates. The medicinal leech, Hirudo medicinalis, and sea slug are classic model systems for studying nociception.[16] Many other vertebrate and invertebrate animals also show nociceptive reflex responses similar to our own.
Pain
Many animals also exhibit more complex behavioural and physiological changes indicative of the ability to experience pain: they eat less food, their normal behaviour is disrupted, their social behaviour is suppressed, they may adopt unusual behaviour patterns, they may emit characteristic distress calls, experience respiratory and cardiovascular changes, as well as inflammation and release of stress hormones.[16]
Some criteria that may indicate the potential of another species to feel pain include:[17]
- Has a suitable nervous system and sensory receptors
- Physiological changes to noxious stimuli
- Displays protective motor reactions that might include reduced use of an affected area such as limping, rubbing, holding or autotomy
- Has opioid receptors and shows reduced responses to noxious stimuli when given analgesics and local anaesthetics
- Shows trade-offs between stimulus avoidance and other motivational requirements
- Shows avoidance learning
- High cognitive ability and sentience

Did you know that human beings actually KILL other animals to EAT them ? Don't you find that disgusting ? They even have built factories to INDUSTRIALISE the process of killing the other sentient animals and chop them in small portions that they pack in plastic. WOW. At first I didn't want to believe it but I have seen the proofs. It's 100% true. They eat dead corpses of animals that are made of exactly the same stuff as them, and almost every human being find that this is totally normal. They even encourage their own LITTLE CHILDREN to eat dead corpses of other sentient beings, imagine that... I mean, what do they have in mind ?? Can't they just think for one second ? I am truly out of words..

we can all agree that slaughter houses are wrong. but eating meat you respect. oh so right

I would name many and many based on that definition.
We will just have to agree to disagree.
Earlier when I was playing fetch with a dog I got the overwhelming feeling of consciousness from the dog.
I see. Well, just don't start shooting people if the damn thing tells you to. Dogs probably don't have much of a capacity for examining a situation and accurately determining the direct and projected ramifications inherent in a specific course of action. Then again, they don't have a clue about past, present, or future, or how such stuff works when factoring through a suite of available options, so there you are.
I'm probably wasting my time here with this exchange. You go ahead and exist on an intellectual par with all the dogs in the neighborhood. Who am I to tell you how to live. You'll probably be much happier in the long run anyway.

So far that means 18 people just realized where their meat comes from.
Congratulations. Next you will learn where your milk comes from (Hint: Not a carton)

I would love to meet that first guy who took a look at a cow and said "I don't know what's in that bag, but whatever it is, I'm going to drink it." Odds are he was drunk as hell at the time.

True story.
