The digestive system is one of the most complex organs in the body, but also one of the most susceptible to disorders, often caused by improper nutrition and industrial pet foods rich in preservatives, thickeners, and additives.
In cats and dogs, as in all carnivores, the intestines are relatively short. This design ensures rapid passage of food through the digestive tract, preventing putrefaction and the absorption of toxins. Unfortunately, industrial pet foods today place significant stress on this system, as they often contain large amounts of toxins derived from food waste, essentially “junk food” in the form of canned or dry kibble.
A healthy, preferably natural, diet is essential for their survival, immune system, and intestinal microbiome.
The digestive system of cats and dogs consists of the same organs and tissues found in all mammals. However, this does not justify the use of synthetic, complementary, or incomplete feeds made from protein, vegetables, or fruit-derived fibers. Today, both pet and human foods are increasingly sterile, heavily processed, rich in chemical additives, and often contaminated with mycotoxins and heavy metals such as aluminum and lead. The quality of their diet has a direct impact on their overall health.
The digestive system is highly organized: each organ functions autonomously but in coordination with the others, each fulfilling a specific role. The system’s primary goal is to provide proper nutrition, ensuring the assimilation of essential nutrients, including minerals, vitamins, and fats. Metabolic organs transform foreign substances into forms that the body can absorb. All mammals, including humans, share the same digestive organs and fundamental functions.
In cats, unlike humans, taste is largely perceived through smell. Their olfactory mucosa is ten times larger than that of humans.
The digestive system of cats and dogs includes:
- Esophagus
- Stomach, a muscular sac connected to the esophagus and duodenum via the pyloric and cardiac sphincters
- Small intestine
- Pancreas
- Gallbladder
- Large intestine (Colon)
ONLY A NATURAL DIET ensures a healthy digestive process, because, unlike humans, cats, and to a lesser extent dogs, are primarily carnivorous. The more natural the diet, using high-quality ingredients and gentle preparation methods (e.g., steam cooking), the better we can protect pets from metabolic disorders, premature aging, and even cancer.
It is therefore essential to avoid industrially processed foods, which often undergo harmful treatments, generating toxic residues in the body, including:
- High-temperature cooking
- Animal by-products
- Chemical additives and preservatives
Respecting their natural dietary habits is crucial for their digestive health, intestinal microbiome, and overall well-being.
The primary difference between the cat’s digestive process and that of humans concerns the speed and efficiency with which certain foods, particularly meat, are digested.
Nature provides everything necessary for growth and the maintenance of health.
