With their own television program on the Animal Planet channel, these meerkats have become very popular creatures.
On a recent trip to the San Diego Zoo, I stood there and watched these delightful animals play and interact with each other for hours in their habitat. If there are any strange noises, they would all stand alert and look around for danger. When they are convinced no prey is within range, they go back to their business.
In the 3rd picture, a large plane was flying overhead and one meerkat got immediately suspicious. Before I knew it, the whole colony was looking towards the sky for the threat.
