Is beef and lamb vegan?

No they aren't. They are "herbivores" which isn't the same. "Vegan" means you chose that specific lifestyle and made some sort of commitment to abide by the parameters withing it's definition. Herbivores like cows (beef) and lamb do not have the choice. They have perhaps what you can call a "vegan diet" but they are not vegans.

Beef is not an animal, but no you cant eat beef or lamb - or any kind of meat for that matter. Vegans are supposed to deny any kind of animal involvment in their food so unlucky mate! On the otherhand though, you could say Cows and Lamb are both Vegans in a way but they're not calssified that way; they are both Herbivores (plant eaters) and theoretically cant be classed as Vegans or Vegetarians etc because its not an informed choice they are making when they only eat grass - its just a natural thing for them not to eat meat.

A lot of animals are vegan, they only eat plants.

Strictly speaking no, as they would eat various bugs that are in the grass.

O yeas. beef and lamb are vegans. the same way pork is ****(faeces)

No meat is vegan.

You are either a troll or an idiot.

If you want them to fit YOUR definition of vegan, them I guess they are

The animals them selves? Sure I guess in that case many other animals would also be vegan.

No! Beef and lamb are tainted!
