Can cats eat spinach? Short answer, yes. Your cat can enjoy spinach as a supplement without any issues because it’s non-toxic. However, cats don’t need spinach because good quality cat food has all the nutrients they need.

As someone who has worked in the pet-grooming business for ten years, I often get this question. Many cat parents wonder if their cat can eat spinach.

Of course, cats can eat spinach in small quantities. However, spinach should only be part of the balanced diet instead of replacing animal-based protein.

What Is In Spinach For Cats

Your cat is a carnivore, and an animal-based diet meets all its nutritional requirements. There is no reason to supplement your cat’s diet with spinach.

However, feeding your cat spinach provides extra vitamins and minerals such as:

  • Vitamin A
  • Vitamin C
  • Vitamin K
  • Vitamin B6
  • Vitamin B2
  • Vitamin E
  • Magnesium
  • Folate
  • Calcium
  • Potassium
  • Iron

These nutrients and minerals can supplement your cat’s diet and improve overall health. However, spinach is only good in moderation and can’t be a replacement for meat protein.

What Are The Health Benefits of Spinach for Cats?

While your cat is an obligate carnivore, it can still benefit from the essential nutrients and minerals in spinach in several ways, including:

Immune Support

The vitamins, minerals, and antioxidants in spinach can support your cat’s immunity in several ways.

  • Vitamin A supports the development and maintenance of healthy skin and mucous membrane that acts as a barrier against pathogens.
  • Vitamin C has antioxidant properties that can help protect immune cells from damage caused by free radicals.
  • Vitamin K helps in the formation of proteins involved in the immune system.
  • Iron supports the production of red blood cells that transport oxygen to immune cells and tissue.
  • Beta-carotene and lutein can neutralize harmful free radicals in your cat’s body.

Digestion Aid and Support of Bowel Health

Spinach is an excellent source of fiber that can improve your cat’s digestion to prevent bowel disorders such as:

  • Constipation
  • Diarrhea
  • Diabetes

A healthy gut environment will help maintain a robust immune response by promoting beneficial gut bacteria and preventing the growth of harmful bacteria.

Weight Management

Spinach is low in calories and contains fiber. It can be excellent for weight management if your cat is overweight.

Even when your cat isn’t overweight, the leafy vegetable will get your cat’s tummy full with fewer calories, lowering the chances of getting obese. More importantly, spinach has the right nitrate to reduce your cat’s risk of high blood pressure and heart disease.

Eyesight Health

Spinach is a good vitamin A source, essential for maintaining your cat’s healthy vision. The vegetable also has carotenoids like zeaxanthin and lutein that prevent cataract degeneration, a common cause of blindness in cats.

What’s more, vitamin C and beta-carotene in spinach can protect your cat’s eye from oxidative stress and inflammation.

While spinach offers nutritious content, your cat can live healthily without it. However, you can safely add it as a supplement to your cat’s diet.

What Are The Side Effects of Too Much Spinach on Your Cat?

Serving your cat spinach can reduce bowel problems and have several benefits. Spinach isn’t toxic to your cat. However, too much spinach or trying to switch your cat to a vegan diet can be dangerous.

Excess spinach in your cat’s diet can cause complications such as:

  • Urinary tract infections: spinach has calcium oxalate that can cause urinary tract infections and bladder stones.
  • Bowel upset: feeding your cat large quantities of spinach can lead to bowel upsets such as diarrhea, vomiting, and abdominal pain. Your cat’s digestive system is only meant to process animal-based protein instead of plant matter.

Other effects of too much spinach in a cat’s diet include:

  • Frequent urination
  • Fever
  • Appetite loss
  • Blood in stool or urine
  • Sudden weight loss
  • Abdominal pain

Although your cat can eat spinach, its best nutrition remains animal-based proteins. Don’t make spinach a significant part of your cat’s diet.

Cooked vs. Raw Spinach: Which Should You Give Your Cat?

Technically, your cat can eat raw spinach. However, raw spinach has more calcium oxalate than cooked one. As we saw earlier, calcium oxalate can cause urinary infections in your kitty.

Your best shot is at cooking the spinach properly. 

How you cook your spinach determines the nutrients your cat can get. The best way to prepare spinach for your cat and retain most nutrients is to boil or steam the spinach.

Avoid any seasoning on your cat’s spinach because its taste buds differ from humans. Do not add:

  • Pepper
  • Salt
  • Other spices

Seasoning the spinach will present extra risks to your cat’s health.

Avoid tinned or curried spinach because they contain additives and spices that are too complicated for your cat’s digestive system.

How Do You Include Spinach in Your Cat’s Diet?

Your cat may not want to eat plain steamed or boiled spinach out of your hand. Spinach smell might not entice your kitty to eat because it isn’t an ideal cat food.

You should find the best way to get your cat to eat spinach.

One best way is to mix the steamed or boiled spinach leaves with wet cat food so that your cat may not notice something new in their food. Alternatively, you can blend boiled or steamed spinach and mix it into their food.

Whichever way you choose, introduce spinach to your cat’s diet in small amounts. Otherwise, your cat might not like sudden change and may ignore the food if they suspect something new. The best solution is to put less spinach into their food at the start.

If your cat likes spinach, you can feed it 1-2 steamed or boiled spinach leaves. However, you shouldn’t worry about feeding your cat spinach daily because it isn’t necessary.

Why You Shouldn’t Feed Kitten Spinach

Spinach isn’t ideal for kittens because they aren’t as developed as adult cats. As a result, they are more susceptible to:

  • Stomach issues
  • Bladder problems
  • Urinary tract issues

Besides, kittens mostly need milk from their mother for most of their life cycle. If they eat anything different, it should be special food to support their growth, and spinach doesn’t cut out.

Can Cats Eat Spinach: All in All

Your cat can eat a small amount of spinach as a treat or snack for a nutrient boost. However, don’t replace its regular diet with spinach because cats are better off with animal-based protein.  

While beneficial in moderation, too much spinach can negate its benefits in cats.


Can cats eat spinach raw?

Yes, cats can eat raw spinach without any issues. However, your cat would enjoy cooked spinach better because it kills all the bacteria that can make it sick.
Regardless of the type of cooked or raw spinach, you should feed your cat in moderation because spinach is high in oxalates that can bind with calcium to form kidney stones.
If your cat has any underlying health conditions like kidney disease, consult your veterinarian before feeding it spinach.

What are the benefits of feeding spinach to cats?

Spinach is an excellent source of:
Vitamin A (essential for your cat’s vision)
Vitamin C (an antioxidant that can help protect your cat’s cells from damage)
Vitamin K (necessary in the synthesis of protein that helps in blood clotting)
Fiber (improve your cat’s gut health)
Magnesium (enhances your cat’s muscle and nerve function)
Folate (helps in red blood cell formation)
The vitamin and ingredients spinach supply can help keep your cat healthy and prevent certain health problems.

What are the risks of feeding spinach to cats?

While a small amount of spinach is not toxic to cats, excess feeding risks the following health conditions:
Kidney stones: oxalate in spinach can interfere with calcium absorption to induce the formation of kidney stones.
Digestive problems: some cats have difficulty digesting vegetables, leading to gastrointestinal issues.
Nutrient imbalance: While your cat can get some minerals and vitamins from spinach, it isn’t a significant source of nutrition for your cat. Your cat’s primary food should be animal-based protein.

How much spinach should I feed my cat?

A small amount of cooked spinach (about one leaf per day) is a safe and healthy treat. If you’re unsure of how much to feed your cat, consult your vet.
