Updated June 2023

Despite our best efforts, cats are still susceptible to food allergies, upset stomach, smelly stool, and other life-altering digestive problems. Since ongoing digestive concerns may have lifelong effects on a cat’s overall health, we suggest doing everything you can to nip kitty’s gastrointestinal issues in the bud. There are a wide range of digestive supplements available to improve your cat’s condition, ranging from tasteless probiotic powders, delicious treats, and flavorful fish oils, so the good news is that you have plenty of methods to sooth your kitten’s insides. It’s up to you to find the best digestive supplements that will quickly remedy your cat's symptoms, but don’t forget to consider the importance of convenience; some cats just won’t want to take their medicine.
