Gas can be further classified as borborygmus, rumbling gastrointestinal noise and flatulence. The two most common causes of gas are swallowed air and bacterial fermentation of certain nutrients. Legumes, such as soybeans, are notorious gas-causers as are milk products when ingested by animals with lactase deficiency. Spoiled food is particularly likely to yield odoriferous gases, such as methane.
The management of gas begins with a change to a highly digestible, low-fiber cat food diet of moderate protein and fat content, which can be prescribed by your veterinarian. Feeding a cat small meals several times a day may cut down on a cat’s tendency to gulp cat food and air during once-a-day feeding.
