Cat Anatomy

Just How Fast Can a House Cat Run, Anyway?

Cat anatomy is quite similar to that of other animals. For instance, they have a cardiovascular system that contains a heart and blood vessels. Cats also have a respiratory system consisting of trachea and lungs. They have muscles and bones, with skin and hair covering all. However, they do not sweat through their skin like humans do, but only sweat on their noses and the pads of their paws. To cool off, cats, like dogs, have to pant.


How many muscles does a cat have? There are 32 of them just to control the ear! In all, a cat has 517 muscles. A cat's heart beats 120 times a minute when resting and 240 beats a minute when active. In general, smaller animals have a quicker heart rate than larger ones.


What about a cat's purr? How do they do that? Cat anatomy includes a blood vein called the vena cava. This vein narrows where it pass into the liver and diaphragm. When the cat is relaxed, the blood in this vein forms ripples, which make the vibrations we feel when a cat is purring.


On each front paw, cats have five claws, and on each rear paw, they have four. It is not unusual for a cat to have an extra toe, however. This oddity of cat anatomy is known as polydactylism.


How many teeth does a cat have? It has thirty, and each one is designed for doing a special job. The teeth of a cat can cut through a rodent's spine. It's molars cut the food into bite size pieces. Cat anatomy is such that cats cannot move their jaws from side to side, so they tend to swallow small chunks whole. A baby kitten grows baby teeth, that fall out at around 6 months. They usually have their permanent teeth around 9 months of age.


Forty percent of American cats are such fat cats that their cat anatomy qualifies as obese. However, the fattest cat in the world may just be Abby, who lives in Atlanta, Georgia, USA. She is reported to weigh in at 76 pounds (35 kg).


How fast can a house cat run? Your cat does seem fast when you need to catch it for some reason! The average cat can run 30 miles an hour (48 km/hour)! Cat anatomy is designed for speed and accuracy is also part of the picture, since a cat is able to jump exactly where they want to. They can do this because of the way their face is shaped. They are one of the few animals that has a flat face. This allows their two eyes to work together for a more accurate 3-D view. Cat anatomy is truly a wonder!
