Baby meerkats are called pups.
Their eyes have a clear, protective membrane, that shields them from dirt while digging. Their ears are close tighly to keep dirt out.
They can not survive in a group of less than four.

We shake hands, they bump noses. Nose-to-nose greetings between cats are unusual, as it puts both in a vulnerable position.

However, cats who know each other well feel safe enough to do this.

It helps them confirm visual recognition and gain information about how the other cat is.
