Fecals enable veterinarians to determine if your pet has intestinal parasites such as roundworms, hookworms, whipworms, coccidia and giardia. Since intestinal parasites live in your petâs gastrointestinal tract, they are usually hidden from view. Unlike external parasites like fleas and ticks, most intestinal parasites are never seen. The only way to detect the presence of intestinal parasites and identify them is by doing a fecal.
Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine.Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food.n the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food).
It takes between seven and 16 hours to absorb all of the necessary fluid. Overall, it can take between 30 and 40 hours for food to fully pass through your colon, assuming a healthy diet and no constipation.
