It’s common for canned cat food to contain guar gum, which is an extract from guar beans. Recent controversy over the ingredient has some cat parents concerned. But before you throw out all your cat’s food, let’s go over why we use guar gum and what effects it has on your feline’s health.

Why do pet food companies use guar gum?

Guar gum is used to prevent separation in the manufacturing process. Pet food companies make canned food in huge batches. They add meat, fruits, veggies, and several other ingredients to the formula. They then divide the batch into individual cans. Guar gum prevents the heavier ingredients from settling to the bottom. This process keeps some cans from being filled with mostly carrots and others from being all meat. Guar gum also keeps the ingredients in each individual can from separating. This way you don't have to stir up the contents after you open it.

How does guar gum affect your kitty’s health?

Ultimately, guar gum is a type of fiber. The right kind of fiber is healthy in the proper amounts. It improves digestive health by promoting good bacteria in your cat’s gut. These bacteria decrease inflammation and boost immunity in other parts of your kitty’s body. Fiber also protects the lining of your cat’s gastrointestinal tract. However, just like with your favorite snacks and treats, too much of a good thing can be harmful. As the fiber in your cat’s diet increases, digestibility decreases, and fewer nutrients are absorbed. In this case, too much fiber will cause your kitty to have loose stools or poop more than twice a day.
