Yes that's true about the Zebra capability. I'm guessing the Zebra heard something. Many of the animals that graze do this behavior to help protect the herd.
I think the zebra that seems to be looking out is doing just that. Zebras are often attacked by larger cats, such as lions and cheetahs, and one of their best defenses is speed. Their other defense is a really strong kick that can stun or kill an attacker.
I remember a cartoon zebra for Fruit Stripe gum in the 1960's. It was a somewhat disappointing gum from what I remember - the flavor was gone within a few minutes. Perhaps if they had spent more effort in getting the flavor to stick around than getting the striped gum, it might have been more popular.
I haven't thought of Fruit Stripe gum in years and you are correct, they used a cartoon zebra in their advertising. Some strong flavored gum from around that time period I remember was clove gum which I loved and Blackjack gum which I hated.
Cheetahs don't come in herds. If their in a group, like mother and offspring - there called prides. Was bummed one day growing up, I was sick and my family went on a safari to see the animals. They arrived back and said they saw a leopard.
