All About Cats - Part 2 (Metabolism)
As with dogs, cats look very different from people, but share many of our body’s characteristics. For example, they have a circulatory system to carry blood and a heart to move it, lungs to breath, and a digestive system to absorb nutrients and get rid of waste, etc.
Like dogs and people, cats come in many sizes and shapes and about 40 different breeds (ex., Siamese, Himalayan, Persian). Most of the cats we have in our homes are either domestic shorthair or longhair varieties and are generally mixtures of different breeds.
Cats have a rapid metabolism when compared to humans. They have a higher normal body temperature (101.5 degrees F, 38.6C), faster heart rate (120 to 140 beats per minute), breath faster (16 to 40 breaths per minute), and mature faster (average life span 12 to 20 years, depending on breed, diet, health care, etc.).
