Yes, animals are made out of cells. In fact, all living things, including plants, animals, fungi, and bacteria, are made up of cells.

Here's why:

* Cells are the basic unit of life: They are the smallest structures that can carry out all the functions necessary for life, such as taking in nutrients, producing energy, and reproducing.

* Multicellularity: Animals are multicellular organisms, meaning they are composed of many cells working together.

* Specialized cells: Different types of cells in animals have specialized functions. For example, muscle cells contract for movement, nerve cells transmit signals, and blood cells transport oxygen.

So, whether it's a tiny ant or a giant whale, they are both composed of countless cells working together to form the complex organisms we know.
