    Buyer’s Guide

    Loose cat stool isn’t fun for anyone. While we’ve covered many of the top choices for cat food that help with sensitive stomachs, diarrhea, and loose stool, you may want to search on your own. Here are some things to look for:

    Quality Ingredients

    Naturally, a cat with a sensitive stomach may be more sensitive to artificial ingredients and preservatives, or fillers that aren’t part of the wild diet. Look for foods with limited ingredients and free from corn, soy, peas, and other hard-to-digest vegetables.

    Prebiotics and Digestive Support

    Many of the foods on this list contain prebiotics, fiber, and other types of digestive support. These formulas are intended to help with the specific physiological processes that lead to diarrhea and loose stool. Prebiotics add natural, good bacteria that aid digestion, while fiber bulks up stool for a firmer consistency. When you’re shopping, look for foods that contain these types of ingredients for digestion.

    While these are general guidelines, each cat is different. Some cats may need more fiber and bacteria, while others just need fewer fillers and preservatives. Some cats may have worsening diarrhea from foods high in animal fats and protein.

    Be sure to speak with your vet about your cat’s digestive problems and loose stool to rule out underlying medical conditions. If it’s truly a sensitive stomach, try different foods to see what your cat likes and what helps with the stool. These things take time, however, so give your cat a few weeks on a new food before deciding if it works or not.
