9. Muscle Building

Cats are very effective killing machines, except maybe for a few breeds that will be more placid in nature. They are very powerful animals for their size, with tomcats in particular becoming muscle-packed predators. Of course, to become big and strong, they need to grow and maintain their muscles.

Cats are obligate carnivores and this means that they must have a diet of protein-packed meat. This protein gives them the building blocks they need to grow larger. In addition, it is thought that the sound and vibrations from their purring further helps to stimulate the growth and repair of muscle.
