Then why aren't cows, sheep, horses, or even chickens nearly as cute as kittens and bunnies?
Baby sheep, horses, and chickens are very cute... cows not so much.
They're cute, but I think kittens would win against calves and chicks in a cuteness contest. Or leopard cubs, if you think size is a factor. My point was that cuteness is not well correlated with domesticability or with tastiness.
It's easy to propose explanation for this, harder to test them. Maybe it's because we regard sheep and chickens as food animals while kittens are companions and friends?
Regardless, your original point stands - human babies aren't as cute as many animal ones.
It still seems like the dominant feature for cuteness is being a baby. An evolutionary explanation that did not explain that would be very strange.
What if it's a flag for imprintability?
A cute, unattended creature is a potential investment, with the hardest part (childbirth) already taken care of. Large eyes, brains, and paws relative to the rest of the body is a physiological consequence of incomplete development, and most mammals have some potential use or other to whoever they recognize as 'parent.'
What possible use can a foster-child ever be to a non-human parent? As for human adoptive parents, animal cuteness does not seem strongly correlated with usefulness. Apart from the few species we domesticate anyway, how are "most mammals" of any use to us?

If this happened in the wild, that momma pig would eventually have adult tigers ready to fight alongside her legitimate offspring, which could conceivably help to defend them from predators. At the same time, adopted tigers won't compete with the other piglets for root vegetables as a food supply. Combined-arms tactics, almost.
"Most mammals" are made of meat; if all else fails, they're edible. "The few species we domesticate anyway" were low-hanging fruit in terms of suitability for domestication, and also happen to be cuter than many non-domesticated species, which I doubt is a coincidence.
Yes, but there's a theory here that you have the cause and effect backward: they're cute because they're more babyish, and they're more babyish because that's what they're bred for. Apparently, dogs are supposed to look and act like wolf puppies or something. So says Temple Grandin, anyway. Wikipedia agreed when last I looked.
A tiger couldn't grow on pig milk alone - the zoo in that story are giving the cubs meat supplements. Later, the young tigers will need to be taught to hunt to get enough meat. And pigs wouldn't like the games adolescent tigers play. Later on, the tigers could eat other pigs who might have mated with their adopted siblings; or the tigers' own future mates might eat them. There's no way this wouldn't end in tears.
Outside of the few ruminant species who can eat grass, almost all mammals compete with humans for food. Instead of feeding a growing pet for a year, and then making one large meal out of it, you could feed a growing human child for a year. Bad evolutionary tradeoff. The correct decision is to eat that mammal now.
It's not a coincidence. But that doesn't mean we necessarily benefit from it in evolutionary terms. We just enjoy doing it. Those animals that are truly useful, I believe we would have (and in some cases did) domesticated, whether or not they were cute.
Unless you've got a surplus of highly-perishable food, a surplus which will end as surely as winter follows after fall. In that case, the mammal in question acts as a convenient storage device, a bank which will often follow you around of it's own volition rather than needing to be carried.
Even if there's overlap between human and potential-pet diets, that doesn't mean they're in direct competition. Dogs, for example, will happily eat the same fresh meat a human would, but can also survive on gristle and partially spoiled meat that human stomachs violently reject.
Agree. It is interesting that unless you grew up in an agricultural/non-industrialized culture, such things can only be known from reading novels about people that have (and written by people with such first-hand experience).
For example, the book Independent People by Halldor Laxness gives an idea of how critical a domesticated animal could be for survival. In the story, the main character's wife died because he wouldn't keep her a cow. Relevantly, he raised the child she left (their child, in fact) because the child was cute more so than out of duty. When the child was 15 or so and less cute he forgot all about her.
The book is longish but so good. He's got like 50 pages in a row about minute details about sheep.
Plausible. How often do people eat most or all of their tame animals in late autumn, and adopt new animal babies in spring, instead of maintaining bigger herds of tame animals that can reproduce to replace the ones eaten? I remember hearing about something of the kind, but can't recall the details...
The question is, then: how viable is taming and raising animals for short periods of time before eating them?
Spoiled meat isn't something you have a reliable supply of. You can't raise a dog just on spoiled meat and other things humans won't eat.
Thousands of years of history of people raising pigs suggests otherwise. Dogs appear to have been domesticated at least partly because they were able to help with hunting and presumably the widespread adoption of canine companions is evidence that humans benefited from the relationship more than enough to compensate for any upkeep costs.
As I said, useful species like dogs and pigs are domesticated because of their usefulness; their cuteness is not a prime consideration. Piglets aren't champions of cuteness. Puppies are cute, but grown dogs or wolves are dangerous and must be very frightening if you're not used to domesticated ones.
Calves are actually pretty cute in person, they're not as photogenic though (we had a farm at school so I've been around lots of young farm animals).
