In Uganda, Africa, there is a kind of mouse that can eat cats. This kind of mouse is similar to ordinary house mouse, except that it has a hard shell on its mouth and grows very hard. This kind of mouse will give off a strong smell, and the cat will be paralyzed, trembling and unable to move after smelling it. At this time, the mouse jumped up, grabbed the cat's throat with sharp teeth, absorbed the blood, and then dragged the cat to a hidden place and ate it slowly.

Nepenthes have the ability to prey on insects. The bottle-shaped body at the top of Nepenthes leaves is a tool for preying on insects. The opening edge and cap of the bottle can secrete honey and attract insects. The bottle mouth is smooth, the insects slide into the bottle and are submerged by the liquid secreted by the bottom of the bottle, and the nutrients of the insects are decomposed and gradually digested and absorbed.

Some crocodiles living in the upper Nile River in Africa usually attack small animals in the water, but they are quite "friendly" to thousands of birds. We can see that thousands of birds often jump freely in the crocodile's mouth to catch the residue in its teeth.

Goose and walrus have one thing in common when they sleep, and both have a precaution. The difference is that when hundreds of walruses sleep together, the walrus on guard is tired, and it will wake up its companions to "change their posts".
