Yes. The other person said they were "carnivorous" though. Giant tortoises are not carnivorous.

Horses are also not carnivorous even though they do eat meat on rare occasions to survive.

Words mean things.

You're also wrong about horses. Put a steak on the ground in field of plentiful grass, horses will ignore it until it's rotted away to nothing. They do not just eat stuff outside of their regular died because its risk free and easily obtained.
