Does gastrointestinal cat food work?

Gastrointestinal cat food can be effective for managing and improving gastrointestinal issues in cats. Gastrointestinal cat food is specially formulated with ingredients that promote healthy digestion and are highly digestible. These diets often include easily digestible proteins, limited ingredients, and a balanced blend of fibers to support the gastrointestinal tract's function.

How long should I feed my cat gastrointestinal food?

When it comes to feeding gastrointestinal cat food, the duration can vary depending on the underlying condition and the specific needs of your cat. For cats with absorptive intestinal disorders, such as malabsorption or maldigestion, gastrointestinal cat food may be fed for up to 12 weeks or as advised by your veterinarian. These conditions can affect the cat's ability to absorb nutrients properly, and the specialized diet aims to provide easily digestible nutrients that are gentle on the digestive system. After the recommended duration, your veterinarian will assess your cat's progress and determine if a transition to a different diet is needed. In cases where a cat requires nutritional restoration, such as after a period of illness or surgery, gastrointestinal cat food may be fed until restoration is achieved. This can involve providing a highly digestible diet that supports the healing process and helps the cat regain proper nutrition. The duration will depend on the individual cat's needs and their ability to recover and maintain adequate nutrition. Your veterinarian will monitor the cat's progress and guide you on the appropriate duration.

Feeding guidelines are general recommendations only. The amount of food required by your cat may vary above or below that listed in this feeding guide. In consultation with your veterinarian it is recommended that you weight your cat 4 - 6 weeks after starting a new diet in order to adjust food intake to maintain or achieve an optimal body weight and body condition score. Consult your veterinarian for specific feeding guidelines for your cat. This diet is formulated to be complete and balanced. It is unnecessary to feed leftover foods, kitchen scraps or additional supplements. It is recommended that your cat be fed 2 - 4 equal portions of the diet per day. Ensure fresh drinking water is available at all times. Store this product in a cool, dry place.

Transition Instructions

We recommend at least a 7 day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet's digestive system to smoothly adapt to the new food.
