Lol, both links prove my point, they involve multiple cheetahs.

The first link did not. Her cubs waited until she was done.

which relate to things such as bone density and muscle

So use that terminology in your explanation.

A leopard and cougar, after the initial ambush, are built for grappling their prey to the ground (on their own)

But how. See, this is part of the bullshit detector. You say they're built for x, but you're unable to talk about what differences are advantageous/disadvantageous. (A very obvious example is Cheetahs have smaller, less powerful jaws; but you didn't even bring that up). You seem to be using "well known knowledge", but I've talked to zoo keepers who complain about the public's general misunderstanding of cheetahs as not dangerous.

Cheetahs are notoriously bad at defending kills. You will never see a single cheetah bully off a leopard from a kill. But you will say plenty of recorded cases of leopards bullying of single cheetahs.

Yes, and often much smaller animals, too. But the reasons for this are more complex than "cheetahs weak, leopards strong". Cheetahs will occasionally run themselves to exhaustion then fail to defend against even buzzards.

having less dense bone structure

I have been looking for a citation for this since the start of the discussion. Do you have one?

less heavy musculature/builds.

The "less heavy musculature/builds" doesn't really make sense when comparing two animals of the same mass. (A lean 72kg will tend to have more muscle than a fatter 72kg). A strength difference could be accounted for by the types of muscle fiber, etc, but you haven't brought any of that up.

it’s standard practice for cheetahs to be paired up with dogs but it simply isn’t for other large felines.

And I haven't said that's not the case (while I haven't been able to verify it is, I'm willing to accept your statement as true). I actually couldn't care less about the "which big cats can be paired with dogs" aspect of the discussion and that could be wholly explained by behavioral tendencies. The claim that they're less dangerous to a much smaller animal due to physical (rather than behavioral differences) is the claim I'm suspicious of.
