Pet Diet: Can Cats Eat Lettuce?

The short answer to that question is YES. Your cat can eat lettuce, but it can be a strange yet fascinating experience, mainly if your feline friend usually eats specially-made cat food.

Nonetheless, you can attempt to feed your cat some lettuce. But, your pet may not like the smell or taste of this leafy veggie. Also, don’t force-feed your cat with it; otherwise, you might be getting a scratch (or two).

On the one hand, if your kitty decides to munch on the vegetable, and with glee, then, you’re in luck!  Not only is lettuce safe for them, but your feline friend will get several benefits from it.  As a bonus, lettuce can be a less expensive cat food. If you’re on a tight budget and don’t want to risk getting your pet hungry, why not give this veggie a try?

Benefits Of Lettuce For Cats

Aside from feeding your pet cat food, you can also feed your kitty some lettuce. Here are some benefits your cat may receive from eating this green, leafy vegetable regularly:

1. A Low-Calorie Treat

Some fur parents like to see their feline family members chubby or “chunky”. Although your pet will look cute, a “round” shape for a cat tends to mean that they’re obese. If your cat is struggling to maintain a healthy weight, it will lead to health complications, such as respiratory problems and heart concerns.

One way to help your kitty slim down is to feed them lettuce regularly. Change your pet’s diet to include this vegetable as it’s a low-calorie food. But, don’t mix lettuce with tons of cat food as it defeats the purpose. Make sure to measure your pet’s food intake daily to avoid issues, like obesity.

2. High Water Content

Lettuce is also a great snack or side dish for kitties who have trouble staying hydrated. This vegetable helps keep your pet hydrated as it has over 90% water content.

Use lettuce to keep your cat safe from painful urinary tract infections (UTIs). Lettuce can also help supplement your cat’s daily water intake to ensure that they stay hydrated, especially during the hot summer months.

3. Rich In Fiber

Dietary fiber is an excellent nutritional component in your cat’s daily diet. However, this type of carbohydrate doesn’t only help humans, but can also be a practical solution for cats’ extraordinary digestive health.

Feeding your kitty lettuce can help in the relief of some digestive issues, such as constipation and diarrhea. If you find your cat having problems defecating, consider adding lettuce to their daily diet.

4. Rich In Vitamins

Lettuce leaves not only contain dietary fiber, but they’re also rich in other vitamins and nutrients, including folate and vitamins A and K.

Folate can help prevent intestinal diseases in cats. Vitamin A helps keep the liver in check, while vitamin K helps improve blood clotting time in wounds.

You might think that your cat doesn’t need the additional nutrients if they’re already eating high-quality food. However, supplementing with lettuce leaves can further improve their overall well-being.

5. Helps Cats Ignore Houseplants

Do you see your cat “attacking” your houseplants aggressively?  If so, you can pacify this particular cat behavior by feeding your feline a piece of lettuce whenever they get a little feisty. Let your cat feast on a lettuce leaf if you think that they’re trying to take one too many bites out of your houseplants.

The five benefits mentioned above are only a few of the many advantages of letting your cat eat lettuce frequently. However, you should take note that there might be some risks involved in feeding this leafy veggie to your feline friend.

Health Risks Of Cats Eating Lettuce

Lettuce can be a nutritional part of a cat’s daily diet, but you shouldn’t fill their bowl with anything but this type of food. Always remember that cats are carnivores. Ergo, your furry feline friend needs meat to survive. However, it doesn’t mean they can’t eat a lettuce leaf or two every day.

Lettuce, despite its low-calorie count, might not fill your pet’s daily recommended calorie intake. Like humans, cats need to reach a particular amount of calories per day to be at peak health.

One lettuce leaf contains about one calorie. Hence, if your cat needs about 200 calories per day to remain healthy, you’ll need to feed them 20 lettuce leaves per day. Good luck with your cat trying to finish those vegetables without getting sick of it.

Feeding your cat with a couple of lettuce leaves per meal should only net about two extra calories for that dish. But, if you’re going to put nothing but two lettuce leaves in your pet’s bowl, the animal will only gain two calories for that meal. This  can lead to malnourishment and other health concerns.

How To Make Your Cat Eat Lettuce?

Do you find it challenging to make your cat eat lettuce?  If so, you can use some techniques to help your feline friend eat this particular leafy vegetable.

1. Feed The Lettuce Raw

Perhaps, it’s best to give the lettuce raw to your cat. Take note that cooking the veggie can reduce its nutritional value.

However, eating a large lettuce leaf might not be ideal for your cat’s small digestive system. If you plan on letting your pet eat this vegetable, make sure to give it in small amounts.

2. Boiling

Aside from giving the lettuce raw, you can also try and boil the vegetable before putting it in your cat’s bowl. Again, consider the food’s nutritional value in this regard, so only boil the lettuce for a short period.

3. Put It In Cat Food

If your cat doesn’t seem to touch raw lettuce, you can mix this vegetable with your pet’s regular food. For example, you can exchange rice with shredded lettuce leaves. Otherwise, you can put a small amount of this vegetable in soup or meat.

Can Cats Eat Other Vegetables?

Now that you know how to feed your cat lettuce, it doesn’t mean that they can eat all types of vegetables. Thus, it’s essential to determine the vegetables that your cat can and can’t eat.

For instance, broccoli is a safe option, and this particular vegetable is relatively easy to prepare. Plus, broccoli has beneficial components, like dietary fiber and potassium. Furthermore, this veggie is rich in antioxidants to help boost your feline’s immune system.

Another excellent vegetable for your cat is spinach. This sweet-tasting veggie is a rich source of vitamins and minerals, along with anti-inflammatory properties. Thus, you can add spinach to your kitty’s daily diet if they are experiencing inflammation-related issues, like arthritis and muscle pain.

Broccoli and spinach are safe vegetable choices for your cat to eat, but avoid the following veggies:

  • Onions
  • Mushrooms
  • Garlic
  • Leeks
  • Chives

Onions are toxic for your cat’s system since these contain thiosulphate, which may bring damage to your pet’s red blood cells. All onion forms are toxic for your cat, so don’t feed your pet whole, chopped, raw, or cooked versions of this vegetable.

Chives, garlic, and leeks also produce similar effects to onions, with garlic relatively being the most potent out of the three. However, the onset of these adverse effects seems to be gradual. If you see signs of toxins rising in your cat, don’t hesitate to rush the poor animal to a local veterinarian.

Can Cats Eat Vegetable-Flavored Treats?

The answer to that question is a “Yes” and a “No”.

Yes, your cat can eat vegetable-flavored treats. The presence of veggies as ingredients in cat treats can provide your pet with a much-needed health boost. But, always be wary of other ingredients included by manufacturers.

For instance, avoid ingredients like butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and ethoxyquin. These harmful chemical compounds are preservatives meant to lengthen the shelf life of certain products. Both BHA and BHT can become carcinogens or cancer-producing components when consumed. Also, BHT can cause kidney and liver damage.

Consequently, ethoxyquin is illegal and unsafe to put in human food, but not in pet products. However, this particular chemical preservative may also cause physiological harm to your feline family member.

Can Kittens Eat Lettuce?

Aside from adult cats, kittens can also eat lettuce. However, make sure that the young cat still consumes the recommended vitamins and minerals to supplement their healthy growth daily.

You can feed your cat lettuce and the occasional milk. Other options include high-quality, canned kitten food.

Serve these ingredients in an easy-to-eat bowl, and make sure to feed your kitten several times daily. Adjust your pet’s diet when they reach the five-week mark. From here, your cat already has the digestive system that can handle larger and tougher food options.


Cats and kittens can eat lettuce, but make sure that you don’t disregard other parts of their healthy diet. Also, watch out for the vegetables that your pet feline can’t eat. If you accidentally feed “Fifi” a piece of onion or mushroom, don’t hesitate to immediately consult the services of a veterinarian to keep the effects from worsening.
