I’m male. Voted for option #5.
I think, in terms of my strictly emotional reactions, that I have a sort of “Great Chain of Being” thing going on. I get sort of creeped out by a “lower” animal preying on a “higher” one. So, a cheetah can eat a gazelle–a cheetah is a fellow mammal, so it’s “allowed” to eat other mammals. (Heck, I eat other mammals.) For, say, a leopard eating a chimpanzee, I’d probably root for the chimp. For a jaguar vs. a monkey…I like cats, so I give all of them points, so despite the fellow primate status of the monkey, I might still root for the big kitty-cat.
Birds–like say an owl–eating rodents…still OK. Birds are technically dinosaurs, I guess, but they’re warm-blooded and provide a high level of parental care to their young; and on the other side of it, it’s just a rodent.
And of course birds and mammals can catch and eat all the lizards or bugs they want.
But something like a crocodile vs. a gazelle? Crocodiles are scaly and cold-blooded and sort of monstrously prehistoric. I don’t like to think of things like that preying on fellow mammals. And, while I’m not super-ophidiophobic, I definitely am not one of those people who could feed live mice to a snake, nor do I have any desire to keep snakes as pets. (It’s OK when cold-blooded scaly reptiles eat other cold-blooded scaly reptiles, though.) A shark eating some kind of fish? That’s OK. A dead-eyed, horrible-toothed, hell-creature-that’s-been-around-since-before-the-dinosaurs eating, say, a seal, is unacceptable.
Spiders eating insects is perfectly OK. (I was a big Charlotte’s Web fan as a boy.) But those spiders that catch birds?!? That’s just wrong, man! Or even a spider catching a frog or a lizard. Invertebrates are not permitted to eat vertebrates. And those giant cave centipedes that take BATS are clearly an affront to all that is right and proper.
All of this is mostly tongue-in-cheek, and intellectually I know perfectly good and well none of it really makes any sense. But emotionally…centipedes eating BATS?!? Brrr!
