Again, you're not going to really find anything suggesting that cats can empathise because it would be a crazy thing to research. But it's not because there's consensus that they can't - it's more because research suggesting either way is unlikely to be credible whatsoever (empirical research anyway, discussion of the problems inherent in these questions and viewpoints happens pretty routinely, though in other parts of academia, see below). Cats play with mice in a manner that could be consistent with cruelty, but it could also be consistent with other, more basic systems of stimulus and response. And there's no good way to tell the difference. It's hard to even define what empathy is supposed to mean. What exactly are we testing for? It's even harder to find some way to actually test it once we have decided on some notion of empathy. Those that believe the behaviour to be indicative of cruelty think that's a simpler hypothesis because they know that other creatures (humans at the very least) are capable of cruelty, so assuming that cats are like other species is simpler. The opposing side believes that fewer assumptions about higher-order beliefs, despite evidence for higher-order beliefs in other species (again humans at the very least), is simpler. So it's really more of a question of philosophy of science than it is an empirical one. This is why you're actually more likely to find interesting stuff on this digging through the philosophy literature (unfortunately, it can be really hard to know what to search for, but see below for something resembling an entry point, and you'll likely strike some paydirt looking through discussions of ethics involving animals).Generic Gamer said:What I meant is that whilst you can't compare cats and dogs directly you can make tentative assumptions about them. It's like comparing apples and oranges, they're not the same but you can make some observations about fruit.Jaime_Wolf said:snip
I'm aware that intelligence isn't a linear scale and that there are different ways to measure intelligence (for instance, cats seem to trump dogs on spatial awareness and problem solving) but the literature I can find on cats seems to indicate that they are way below the threshold for self awareness and have a tiny emotional range. The literature I'm talking about is mainly from my uni's ebook selection whereas the contrary opinion seems to be backed up more frequently online, but by clearly biased sources (anecdotes from cat lovers etc.)
I think the most obvious point is that emotional development seems to be linked to social group size. All of the animals reckoned to be really emotionally aware are animals with tight social groups, cats would have no benefit if they were sophisticated enough to be cruel.
AS I say, I can only go off of what I have read (this isn't my field but stick me in a library and I go nuts) but cats don't seem to have the mental equipment to actually consider themselves, much less abstractly imagine another animal's suffering as their own and almost certainly not the reasoning ability to then choose to inflict pain for amusement.
I literally cannot find a credible source that says cats can empathise.
Certainly, I don't think anyone would agree that there's a certain "threshold" of intelligence (whatever that's supposed to actually mean) for self awareness. To my knowledge, you're right about emotional range varying strongly with social behaviour, but I'm not aware of any such credible link between social behaviour and self awareness (again, such links are impossible since there are no accepted measures of self awareness). Regarding the range of emotions assumed of cats, you're also right about that, but when you attempt to catergorise emotional responses into discrete categories, you can come up with a very small number of categories for pretty much all species (including humans). And I'm not sure how much one should ascribe such descrptions to a limited range of emotions or to the process of categorisation itself. Researchers are almost always wary of whether categorisations like this actually represent some analytic insight, or just represent a particular descriptive system (and there are a whole host of entirely separate philosophical problems with this too).
This is the same reason that assumptions about self-awareness are so fraught with peril and so rarely accepted by experts. It's hard to know what we're testing (how can we be sure that they're self-aware and not just behaving in a way that happens to be consistent with self awareness for lower-level reasons?). If you're interested, a good starting point on the problems inherent in testing for these things can be found by looking into the philosophy literature and searching for discussions of philosophical zombies (philosophers occasionally come up with some pretty great names for things) - such discussion is about humans, but humans actually present a parallel problem in attempting to prove that humans other than yourself are self-aware in the same way that you are.
Most of these issues are simply inconclusive. No one really has a very good idea either way. The answers are unclear. How to test for them is unclear. Hell, the questions are unclear. Modern animal psychology, by and large, is pretty unconcerned with these questions for these reasons.
(I have been reading your edits by the way, just didn't bother redoing the quoting.)
(Also, this is veering closer and closer to issues that I do work on and worry about regularly. Sorry if I bog down or start getting a bit overly zealous.)
