The digestive system of the cat is a lot like ours. After all, we're both mammals, and our organ structures are very similar. But there are some crucial differences because the cat evolved to be an obligate carnivore, while we humans can eat pretty much anything we want. Take a trip with me through your cat's digestive system and find out what makes your cat tick.
1. The mouth
2. The esophagus
3. The stomach
4. The duodenum and its pals: the liver and pancreas
Bile, a chemical produced by the liver and stored in the gall bladder, breaks up large fat molecules into smaller ones that can be absorbed in the next stage of the digestive process. The enzymes secreted by the pancreas (which unfortunately does not appear in the illustration above) neutralize the acids in the food slurry before the mixture passes into the intestine, and aid in digestion of sugar, fat and protein. The best known of these is insulin, which regulates the levels of glucose in your cat's body.
5. The small intestine
6. The large intestine
7. The rectum and anus
So, why does your cat go to the bathroom shortly after he eats? When food reaches the stomach and the digestive process begins, an "eject your cargo" signal is sent to the colon. This is called the gastrocolic reflex, and it's why cats (and people) feel the urge to poop after they eat.
