Obvious disclaimer that you shouldn't have wild animals as pets.

But like, cheetahs are the only large cats that keepers will do free contact with. Hell, even most small cats don't get free contact. (Because small cats can be VICIOUS. They'll have a baby pallas cat wearing thicker gloves than when handling an owl. Because small cats can just be vicious.)

Like I think the only other cat at our zoo where I've seen free contact with was servals? Because I know they've used servals in shows to demonstrate their natural jumping ability. But I know servals can sometimes have a mean temper as well. Meanwhile they'll do the cheetah run and afterwards put the mic by the cheetahs and it's just like an engine with them purring. It's fascinating to watch when the message in every other large animal is "no free contact because it's dangerous even when they're born in captivity".

Eridians are further behind than humans technologically right? They dont have computers, relativity, quantum mechanics, etc. In fact, Eridians probably dont even know about the Big Bang because their atmosphere would filter out most of the cosmic microwave background radiation we use to detect it. On a human timeline, theyre anywhere between like early-mid 20th century. Rocky's basically a cosmonaut.

So the human civilization is pretty advanced from Rocky's perspective. Rationally he understands this. On a conceptual level he knows this to be true.

Like imagine being a modern day sailor navigating the Pacific with GPS and strong hulls to protect against the raging ocean. And from portside you see like an honest to god viking ship. Except its made of some high tech carbon fiber material. But like, its still very definitely a viking ship. You can clearly see there's 24 oars along the hull where sailors are supposed to use to manually row their ship. Also the ship is leaking and theres like one little dude on board whos skittering around patching the holes constantly. Also this little dude is blind and doesnt know about water. Thats how insane Eridians look being an interstellar species without computers or radiation shielding.
