I suppose there are such animals if we don’t consider accidental critters on the leaves or something.
Many ruminants are known to eat birds occasionally but I would think a koala doesn’t catch a bird Or a sloth
But it’s probably easier to find strictly carnivore animals (prey stomach matter and medicinal herbs don’t count, okay?). If you are a snake, you won’t eat fruits and leaves even in need… And almost all spider species are strict carnivores.
Chickens are very well-known omnivores. Ducks too. I know little about turkeys but no wonder they are the same in this regard.
It’s NOT healthy for most adult mammals, they become lactose intolerant when they don’t need and drink the milk anymore! Most cats are like this, it’s pretty known but interestingly, not all. Probably it helps if they keep getting milk but many still can’t digest it. And we know humans often lose the ability even if they keep drinking milk. Heavy milk drinker anchestors help (I just can’t form as good English sentences as I wish…)
Of course it would be quite bad for the species if a mother would need to feed their adult offsprings instead of raising more babies… They got milk until they needed it then didn’t and lost the useless ability…
The same species is the best, of course but sometimes some other milk is better than nothing… Of course it should be somewhat similar. Milks are VASTLY different, fat content comes to mind but I suppose it’s just the top of the iceberg… People raise kittens with formula but IDK what it contains. Something fatty and protein rich enough for them, I have read cow milk is too low on both for a kitten. Maybe it would survive but now that we have vets and choices, we should give them the better thing, closer to their mother’s milk. Hand-raising a wild animal, I am curious about that too…
Yes we should eat things animals don’t (I mean if we want and if it’s good for us, we can choose not to do that and it may be fine too). I like my cooked food and my dairy. Even the noble fruits bred for and by humans but I don’t consider that actual good food, it’s just joy in tiny amounts
We humans use and do very different things from all other animal species. I won’t stop living in a house and use the Internet either… Just because something is new, it may be good. And we want to thrive, not just survive. Some animal has such a messed up natural diet and lifestyle and everything… But it was enough for survival so it has survived, somehow.
Anyway, we are humans. Even our ancient eating isn’t even remotely similar to some of our pretty close relatives. So you can’t extrapolate much from the diet of great apes if it comes to human’s right diet - let alone the other, more distant groups.
Personally I don’t consider it nice and simple to call not berries berries and berries not berries but it may be me. I like scientific terminology. Where vegetables are nowhere I think… It’s a kitchen term. Fruit is scientific, that’s fine.
I know it’s just me and normal people are fine with kichen/greengrocery’s term. I don’t since the day I learned banana is berry and strawberry isn’t But it’s fine, I understand your terminology now and if I ever mention berries in this thread again, it will be the common usage even if it’s wrong.
But vegs… Are there vegs in Nature at all? I don’t even know where the vegs belong, what is their natural relatives, probably it’s all over the place, some tubers, some green leafy things… Of course the animals with the right needs eat them. If it’s a rabbit, leaves work for them. Carrots are too sugary but they still can eat a little. It’s just not their healthy food, more like candy. But rabbits has nothing to do with us anyway, they would die on my fatty diet in no time… They can’t handle sugar nearly as much as humans either. And they aren’t starch eaters like mice… Their food is mostly greens. But why would it matter if it’s vegetable or not? Green leaves are green leaves, they are somewhat similar I would think… Vegetable is a very wide group, an animal may mostly live on one kind and have problems eating more than a tiny amount of another.
