Brussels sprouts are rich in dietary fiber. These vegetables are loaded with both soluble and insoluble fiber, both of which play crucial roles in supporting digestion.

Soluble fiber provides the nutrients required by your cat’s gut microbiota. Gut microbiota refers to the microorganisms that live throughout a cat’s digestive tract, which promote digestion. Some studies have also linked soluble fiber with reduced risks of blood and cardiovascular diseases.

Insoluble fiber, on the other hand, promotes digestion by bulking up stool while also softening stool consistency. This ensures frequent and easy bowel movement, which may help to relieve various digestive issues like constipation.

2. Brussels Sprouts May Promote Weight Loss

Aiding digestion isn’t the only way your cat may benefit from the dietary fiber in Brussels sprouts. Fiber-rich foods are also cited for their ability to promote weight loss.

Fiber creates a sense of fullness for longer. That’s necessary in fighting food cravings and hunger pangs.

When mixed into a cat’s regular food, Brussels sprouts may reduce the food portions your cat consumes in one sitting. You’ll also realize that it takes a considerably long duration before your furball feels hungry again.

So, could sprouts help with cat weight loss?

Yes, Brussels sprouts can, indeed, help to keep your cat’s weight in check. These vegetables are packed with dietary fiber, which is known to promote weight loss.

3. Brussels Sprouts May Promote Hydration

Like its other cousins in the cruciferous family, Brussels sprouts boast significant water content. 100 grams of Brussels sprouts contains as much as 86 grams of water.

Therefore, this vegetable may promote hydration.

There are times when cats don’t seem to drink as much water as they should. During such times, mixing Brussels into your kitto’s regular food could make a huge difference in averting dehydration.

4. Brussels Sprouts May Speed Up the Wound Healing Process

Cats may spend up to two-thirds of their day sleeping. But these cute, furballs tend to be hyperactive during their waking hours.

Your cat could easily injury himself while prowling or playing with his other furry housemates. And considering that cats are highly territorial, injuries could also result from turf wars.

Now, Brussels sprouts are rich in vitamin K, the vitamin known to promote wound healing. Vitamin K aids wound healing by inducing the formation of blood clots which are necessary for stopping bleeding.

Vitamin K also plays an instrumental role in enhancing bone growth. It can, therefore, help to guard against degenerative bone conditions like feline osteoporosis.

5. Brussels Sprouts May Help Stabilize Blood Sugar Levels

100 grams of Brussels sprouts contain 8.95 grams of carbohydrates and 2.2 grams of sugars. While this may look a little too much for your kitto, only a negligible amount of these sugars finally get into your bloodstream.

The potential adverse effects of the carbohydrates in Brussels sprouts are neutralized by the high fiber content in the vegetable. Note that much of the insoluble fiber in Brussels sprouts moves through the stomach undigested. In the process, it slows down the absorption of sugars into your cat’s bloodstream.

Multiple studies have shown that increased intake of cruciferous vegetables may decrease the risks of diabetes.

Can Cats Eat Brussels Sprouts?

That begs the question, can diabetic cats eat Brussels sprouts?

Yes, the fact that Brussels sprouts come from the cruciferous family of vegetables explains why the vegetable might offer anti-diabetic benefits.

In fact, Brussels sprouts are rich in alpha-lipoic acid, a popular antioxidant widely studied for its positive effects on blood sugar and insulin. These vegetables are also rich in omega-3 fatty acids, which may protect against diabetes by reducing blood triglycerides and insulin resistance.

What’s more, Brussels sprouts are incredibly low in fats. Therefore, you can feed this vegetable to your cat without worrying about cholesterol issues.

6. Brussels May Offer Protective Benefits

Diabetes isn’t the only medical condition in cats that you can manage using Brussels sprouts. The vegetable contains various antioxidants, which may offer protection from a host of other medical conditions. A notable example is vitamin C.

Vitamin C is one of the body’s main antioxidants. It’s also involved in the growth and repair of tissues, as well as the production of proteins like collagen.

Besides vitamin C, Brussels sprouts are also rich in the antioxidant kaempferol, which is noted for its anti-inflammatory properties.

Now that Brussels sprouts contain immune-boosting properties, can cats with kidney disease eat Brussels sprouts?

They sure can. However, follow the thumb rule of moderation. Feeding too much Brussels sprouts to cats with kidney disease may exacerbate the condition as opposed to relieving it.

So, are Brussels sprouts good for cats?

Based on the health and dietary benefits listed above, it’s safe to say that Brussels sprouts are good for cats. But as you shall find in the next section, there are a few side effects to beware of.

Are Brussels Sprouts Bad For Cats?

So far, we’ve gone through a number of potential health benefits of Brussels sprouts for cats. But you might still find yourself wondering, are Brussels sprouts poisonous to cats?

As we mentioned at the beginning, Brussels sprouts are not immediately toxic to cats. However, it’s important to remember that the toxicity of Brussels sprouts depends on how the plants were raised.

Brussels sprouts are generally cultivated in warm, humid environments. High-humid conditions may provide an ideal breeding ground for bacterial growth. A majority of these bacteria are fairly tolerable. But some of them could trigger food poisoning. Sadly, you cannot always vouch for the origin of the Brussels sprouts in your local grocery store. Your only option would be to monitor your cat keenly for any signs of food poisoning.

Another thing to remember before feeding Brussels sprouts to cats is that your feline friend is inherently an obligate carnivore. Obligate carnivores rely almost exclusively on animal products. Therefore, the fact that Brussels sprouts is a plant-based food means there are always risks of gastrointestinal complications.

Common symptoms to look out for include vomiting, diarrhea, loss of appetite, and abdominal pain.

So, do Brussels sprouts make cats fart?

Yes, the fact that Brussels sprouts induce bloating means these vegetables may also cause your cat to fart. However, be sure to rule out other gastrointestinal complications.
