How did they figure out that ‘big cats’ (lions, tigers, leopards, etc.) were actually related to normal-sized cats?

DNA testing is relatively new so I assume it wasn’t that. Did some scientists just go out into the wild and observe lions behaving like cats and think to themselves “I bet they’re related!”, or did they have some other way of figuring it out?

**EDIT:** By the sounds of things they just looked at them and guessed. Luckily they guessed right! Can you imagine if we’d spent all this time calling them ‘big cats’ only to have DNA evidence prove that they’re completely unrelated? 😂

They looked at them?
And when that didn’t quite satisfy the urge they looked at the bones. And when that did not make things quite clear they looked at the rest of the anatomy. And then they looked at the behaviour. And after they looked at all of these things, they knew pretty exactly what they had in common and how they were different.

Edit: And I wanna add: how you dare to suggest that lions are not normal sized?
