I’m actually not too sure how right you are here, my last cat was a chunky boy at 7kg, let’s say that the upper end 68mg is the LD50, I’m roughly 70kg, 680mg of coffee would be very uncomfortable and unpleasant, but I don’t think I’d be hitting the LD50.
LD50 in humans is probably around 100mg/kg, fatal doses are 150-200mg/kg
When you factor in weight, that’s not too far off from where people start dying

Yeah, it really doesn’t take much caffeine to kill a person. Plants literally started using it as a pest deterrent.
Also mint, and chocolate apparently. And of course chili’s. The only one that seems to actually work on us though is nettles.
No one’s domesticated them.
Roughly about 10g of caffeine for a 70kg human is where it’s starts to generally be recognised as lethal
