Feline Nutritional Diarrhea

"Feline nutritional diarrhea involves making it easier for your cat's body to digest food. This includes trying simpler diets such as those that are hypoallergenic and possibly dietary supplements."

Diet is often used when a cat is suffering from what is known as small bowel diarrhea. There is an ongoing debate if it helps cats with larger bowel diarrhea. Every cat responds differently to dietary change resulting in some experimentation as to what works. The goal of changing diets is to reduce the difficulty your cat will have in digesting the food you feed her.

Cats that are suffering from diarrhea need a diet that is easily digestible. This includes a diet that is gluten and lactose free while delivering protein and carbohydrates. Some of the hypoallergenic diets are made this way. These diets usually contain one of the following: lamb, fish, chicken, rabbit and venison. You should avoid commercial foods that contain a combination of lamb, beef, rice and wheat.

Most veterinarians prefer a diet that also contains soluble fiber. Others like to add a supplement that contains psyllium or oat bran. Fiber absorbs moisture and helps to bind the feces.

Some commercial hypoallergenic diets might help such as Hill's Prescription Diet d/d.

If you cat doesn't improve after two weeks with a new commercial diet then a homemade diet might be necessary. A typical homemade diet you could try is white rice mixed with boiled hamburger (drain the fat first). You could also try or cooked chicken.

Alternative Medicine and Feline Nutritional Diarrhea

Several natural remedies are associated with helping to restore balance in the digestive system:

One product worth researching which combines all of these ingredients is RunnyPoo Relief.

Another supplement to help with feline nutritional diarrhea is Omega-3 Pet for Cats. This supplement is known for reducing inflammation and has some clinical support for Irritable Bowel Disease, one of the conditions that cause diarrhea. There is a small risk of side effects such as a problem with the pancreas. This is definitely an option worth discussing with your veterinarian.

Deficiencies in certain vitamins are associated with diarrhea as a symptom. The following table list the vitamins and recommended doses in cats.
