Introduction
By Xinyi Liu
Felines have been domesticated for a long time, becoming cherished companions for humans. Similar to humans, they are colonized by bacteria during birth. When kittens are born, they are exposed to the external environment, leading to changes in their gut microbiota. After weaning, felines consume high-protein foods in large quantities, causing significant changes in the species composition and structure of their gut microbiota.The differing diets of humans and felines contribute to significant variations in the composition of their intestinal microbiota.[1] These gut microbes play crucial roles in the immune and digestive systems of felines. Given their prolonged coexistence with humans, the condition of domestic pet cats' gut microbiota can impact not only their own health but also that of their owners.[2]
Composition of domestic cat intestinal microbiome
The feline gastrointestinal tract harbors a complex ecosystem comprising various microorganisms, including bacteria, viruses, fungi, and protozoa. Among these, bacteria constitute over 98% of the population, and predominantly strict and facultative anaerobic bacteria dominate the gut microbiota. [3]Their metabolic activities generate beneficial molecules like food or drug compounds, enhancing the host's immune response and metabolic capabilities. These intestinal bacteria play a crucial role in regulating the immune system, defending against external pathogens, and supplying essential nutrients, such as vitamins that may be scarce or challenging for the host to produce independently. Gut bacteria in cats play a crucial role not only in digestive diseases like inflammatory bowel disease or alimentary small cell lymphoma but also in the overall well-being of an organism. While the precise mechanisms are still under investigation, it's clear that gut bacteria can impact a wide range of diseases affecting various organs and systems, including but not limited to diabetes, chronic kidney disease, and obesity.[4][5][6]
