Cats with a healthy microbiome have a robust immune system. Since most of a cat's immune cells are distributed in the gut, an imbalance in gut microbes can lead to various health issues such as weakened immunity, skin disorders, and diabetes in pets.

Diseases resulting from weakened immunity may temporarily improve with treatment but are prone to relapse, and symptoms can worsen or lead to more serious conditions. It's important to be cautious. If there are congenital issues with the immune system or if inflammatory conditions persist due to chronic illnesses that compromise immunity, managing gut health through microbiome analysis is crucial for enhancing a cat's immune system. Additionally, consistently feeding a nutritious diet and supplementing with probiotics or other supplements beneficial for gut health can help boost immunity.
