Can they perspire like people?

Because if not, then they can't really keep up.

If kangaroos ever learn to throw rocks, the entire continent of Australia is cooked. They can even carry extra ammo in their pouches!

Technically they might not even need to become carnivores to learn the habit of chasing people down and punching them to death to defend their territory.

Many herbivorous animals eat the occasional animal. You can find heaps of YouTube videos of deer eating birds, and that’s just what’s been witnessed and recorded by humans. Some scientists in California recently recorded a population of squirrels that is very adept at hunting voles. Kangaroos may have developed their speed and strength to elude their extinct predators, they may also occasionally use it for a little protein and calcium snack.

Kangaroos have tiny brains and to be a predator you need to be a bit smarter.
