We’ve learned from scientists that all plants, animals, and humans store information about what they look like on something called DNA.
This stands for “deoxyribonucleic acid” (but you can just say DNA).
In the beginning, God put lots of information inside the DNA of each plant, animal, and human. This information tells living things what they will look like, how to grow, and so on.
As cats have kittens, the DNA of the parents is combined and passed down to kittens. Over the years, these changes have produced the many varieties of cats today.
God gave cats the first DNA that makes them cats. They always make cats, not dogs or anything else. Cats will never grow wings like a bird or fins like a fish!
