Arugula is a bitter and slightly spicy plant that we often put in salads. With its increasing popularity in health food recipes, it is common to wonder if it is safe and healthy to serve to your cat.
So can cats eat arugula? The short answer is yes. Your cat can eat arugula, but there are several things to consider before making it a permanent part of their diet. Keep reading while we discuss feline nutrition and any arugula-related health concerns. We’ll also go over how much and how often you should serve it to keep your cat healthy and happy.

Is Arugula Bad for Cats?
You might hear other people refer to arugula as salad rocket, rucola, rucoli, and several other names. The plant they refer to is common in the United States and picked when it’s young to add to salads. Arugula is not toxic to cats and shouldn’t cause any problems. However, cats are strict carnivores and do not need much plant matter in their diet.
Feeding too much arugula or any plant fibers can cause an upset stomach in your cat, leading to diarrhea and even vomiting. If you don’t wash it well, the arugula can have residual pesticides that can harm your cat. If there is any salad dressing on the leaf, it could render it unhealthy and unsuitable for your pet. Arugula is naturally low in oxalates and is not known to contribute to calcium oxalate stone formation in cats although cats with a history of urinary stones should only receive new foods with veterinary guidance. It’s always best to consult a vet before introducing new foods to your cat’s diet.

Is Arugula Good for My Cat?
Let’s take a look at some of the nutrients present in arugula that make it worth sharing with your cat on occasion.
1. Calcium
Calcium is an essential nutrient required by cats and many other animals. Your pet will get most of the calcium from animal sources like bones, fish, organ tissue, and milk. However, a small amount can come from leafy greens, like arugula.
Calcium helps keep your cat’s teeth and bones strong. It helps with muscle contraction, including the heart, and it helps with digestion and milk production when nursing.
2. Folic Acid
Folate or folic acid is another vital nutrient that you can find in arugula. It helps your cat synthesize DNA, form red blood cells, aid in digestion, boost the immune system, and more. You can find folic acid in many foods.
3. Potassium
Potassium works together with sodium to regulate several body functions. Your cat requires potassium for the proper functioning of the nerves and heart. Potassium imbalances are common in cats with kidney disease.
4. Fiber
Fiber can help support your cat’s digestive system, especially for cats with frequent constipation or diarrhea. It helps regulate stool consistency preventing it from becoming too dry or runny. Fiber can also support overall colon health.
5. Vitamins & Antioxidants
There are plenty of vitamins and antioxidants in arugula that are beneficial to your cat. They are essential for a properly functioning immune system. They also protect the body against free radical damage.
6. Low Sugar
One more positive benefit of feeding your cat arugula is that it is low in sugar and will not contribute to weight gain. Overweight cats are a major concern in America, with as much as 80% in need of a diet. It’s better to find foods that will help eliminate the problem.

How Can I Feed My Cat Arugula?
Most cats like to chew on grass, which helps with digestion, so it shouldn’t be hard to get your cat to try it. Ensure that you wash it well, and if they enjoy it, offer arugula only as an occasional treat rather than a regular part of the diet. Cats can safely consume one small leaf or one-half of a small leaf for smaller cats once or twice per week. Feeding more than this may increase the risk of gastrointestinal upset due to excess plant material. All culinary arugula varieties, including baby arugula, wild arugula, and garden arugula, are safe when served plain and washed. Avoid salad mixes that contain onion, garlic, or other harmful ingredients, and avoid any oils, seasonings, or dressings. Although arugula is low in oxalates and is not linked to urinary stone formation, overfeeding any vegetable may dilute essential nutrients and may be inappropriate for cats with a history of urinary tract disease. Finely chopping the leaf can help prevent choking and make digestion easier. Remember that most of your cat’s diet should come from animal proteins.

Summary
Cats can eat arugula and it can be a nice change of pace from the cat grass and catnip that your pet usually chews on, especially if you grow it in your home garden and don’t need to worry about pesticides. It’s healthy to feed your cats on occasion, and it is non-toxic, low in oxalates, and safe when limited to very small portions one or two times per week, so if you catch your cat eating some behind your back, there is no cause for concern. Overfeeding arugula may cause digestive upset and, in rare cases, may be unsuitable for cats with a history of urinary disease, so moderation is essential.
