So can cats eat lettuce? Yes, it is safe to let your cat eat lettuce, but it should only be in moderate amounts. This means, you don’t want to allow your pet to eat giant salad like you might have yourself. A big plate of greens isn’t going to sit so well with them.

Yes lettuce in general will not be toxic for your feline. However, it does have a lot more fiber in it than your feline eating in his regular cat’s food. As with most fruits and vegetables, lettuce is a good source of dietary fiber which helps aid in digestion.

Since cats are carnivorous animals, dietary fiber isn’t nearly as essential as it is for herbivores and omnivores, too much of it can have a negative effect on your cat’s normal digestive functions. For this reason, it’s very important to moderate the amount of leafy greens that your cat eats.

If they like it and you want to feed it to them, just use it to supplement they’re normal cat food. Do this by adding a few small pieces into their bowl for them.

Supplementing will allow them enjoy the taste and texture and receive the nutritional benefits, while still getting their most important nutrients from their cat food. You can give them a few small bites here and there as just a snack, but careful not to feed them too much lettuce on its own. This could potentially cause some intestinal upset.

If you want to see how your pet responds to lettuce, start by cutting some up into small pieces, as opposed to just offering them a whole leaf. You can offer a few small bites to see how they react or start by adding the pieces to their regular cat food. You can also try shredding the lettuce into grass-like pieces.

If she isn’t into the first time, try again with a different type of lettuce or even just a different part of it.

Benefits of Lettuce

Lettuce does contain more than just water and fiber, and in small amounts there are many benefits to allowing it in your cat’s diet — in reasonable amounts of course. 

Lettuce is great source of vitamins and minerals

A little bit here and there for cat is a great way to boost their intake of important vitamins and minerals that may help them live longer and healthier lives. Some of the nutrients that lettuce can provide include:

  • Calcium
  • Vitamin A
  • Vitamin C
  • Vitamin K
  • Folate
  • Iron
  • Vitamin B6

While it’s very important to ensure your cat’s regular food contains the vitamins and minerals that they need daily for optimal health, it never hurts for them to get a little more from healthy, cat-safe snacks like lettuce.

The dietary fiber can help keep them regular

Dietary fiber is so great for digestion because it adds bulk to bowel movements and helps them pass. A little extra fiber from lettuce can help your kitty have regular, healthy bowel movements, which is essential for optimal health.

Lettuce is a low calorie snack option

Some cats have trouble maintaining a healthy weight. They can easily gain too much weight if they’re having too many calories and not exercising enough to burn them off. It can happen very fast without you even realizing, but a healthy weight is very important in keeping your cat healthy and comfortable. 

Low calorie snacks such as lettuce are a great way to give them a little something without overfeeding them. It gives them something to munch on that isn’t going to lead to them consuming excessive amounts of calories. So if you’re cat just wants to keep eating all day, sneak in some lettuce.

Lettuce can help keep your cat hydrated

Lettuce has a very high water content which can help your kitty get in some extra H2O throughout the day. This extra boost of hydration is great for cats that eat a primary dry food diet, cats that might not be drinking enough water or if they like to stay outside in hot climates.

Keeping your cat well-hydrated is essential in preventing painful urinary tract infections (UTIs), so a little bit of hydrating lettuce as a small snack for supplement in their food is a great way to get in some extra water into their diet. Just don’t rely solely on lettuce as your cat’s means of hydration. 

Always make sure that they have a fresh and easily accessible source of water to drink at all times. Check to make sure they’re urinating regularly. If they aren’t, this is a sign of dehydration.

Cats enjoy variety in their diet, including plants

Although cats are primarily carnivorous animals, they still enjoy some variety when it comes to food and they’ll try just about anything. Allowing your cat to enjoy some crunchy, watery lettuce every once in a while will give them a chance to have something different from their regular food, and you’ll know that it’s going to be safe and provide some benefits.

Lettuce is a good alternative to your house plants and other grass

The truth is — although cats are primarily carnivorous animals – cats love greens in the form of plants and grass. For this reason, you kitty might take a few bites out of your house plants every now and then. Not only does that eventually destroy your plant, it might not be safe for your cat. Some of them can be very toxic for cats.

Additionally, they might eat grass from outside, which is known to cause vomiting. Sometimes, the grass might be necessary to help them clear out something else.

But it isn’t great for them to eat all the time. Giving them some lettuce here and there will help curb that craving and desire to eat other greens that they should stay away from. 

Different Types of Lettuce

When you think of lettuce, you might just think of simple iceberg lettuce, but there are many different types of lettuce. Different kinds will provide different flavors and textures, and your cat might prefer one of the other.
If you want to start incorporating lettuce as a supplement in your cats diet, test out some different ones and see which one they like best. For the most part, cats seem to prefer the darker types, like purple lettuce. This is probably because the darker ones seem to have more flavor. 

Your cat might also prefer the texture of one type of lettuce. Some are crunchy and juicy — like romaine and iceberg — while others like butter and green leaf are soft and leafy. 

Can Cats Eat Vegetables?

Just because lettuce is safe for cats, it’s not safe to assume that all vegetables are going to be okay for them. But there are some other vegetables besides lettuce that you can safely incorporate into your cats diet to add some extra nutrition and variety.


Cooked carrots are a safe, non-toxic snack for cats. You can add a few pieces into their cat food or use it as a snack. Be cautious with raw carrots though. Cats might enjoy the crunchy texture, but they can be a bit difficult for them to digest if you give them too much. When you give them anything new, always do it in very small quantities, just to see how they tolerate it.


Cabbage can be a good snack for cats in small portions. In fact, it can provide your feline with a great source of calcium, vitamin b-6, and cancer fighting properties. If you do choose to feed your feline cabbage, it’s very important that it’s only in small portions, as too much cabbage can cause painful gas. Also, cabbage contains thiocyanate, which can negatively affect your cat’s thyroid if they have too much.

Like lettuce, spinach is another great low calorie snack to incorporate that’s also loaded with beneficial vitamins and minerals. However, you should avoid spinach if your pet experiences any kidney or urinary issues.

Other Safe Vegetables:

  • Squash
  • Cucumbers
  • Peas
  • Cooked Broccoli
  • Green Beans
  • Asparagus

Some Vegetables to Avoid

Here are a few vegetables that are not safe and may be problematic for cats in any amount.

Swiss Chard

Swiss chard contains a high amount of oxalic acid, which experts believe can lead to increase development of bladder and kidney stones in cats. For this reason, they do not recommend feeding it to cats, even in small amounts. 


Kale can be fatal for felines. It contains compounds that can be oxidizing to cats and can even lead to them developing Heinz body anemia.

Leaves of House Plants

You’ve probably come across some plants and grasses that are actually for cats, but this does not mean that just any are okay to feed to your cats. Just because they’ll take a leaf that you offer then or even dig into them on their own, doesn’t mean it’s safe.

Some plants are highly toxic for your pet. If you have house plants, check to see how safe they are if your feline decides to take a bite. Additionally, if they are safe or you’ve bought plants especially for your pet, be sure not to add any chemicals to the plant or in the soil.

A Word of Caution

Although we’ve discussed some of the great benefits that come with allowing your pet to eat moderate amounts of lettuce and other vegetables, it’s important to note that it’s not enough to just feed your feline lettuce and vegetables. In fact, it can be life threatening to just depend on this alone as their diet. 

Remember, cats are still carnivores and their bodies need meat and high protein diets for survival. This is scientifically proven and not just the opinion of a few people. If you are only feeding your cat lettuce, they will become extremely malnourished and eventually die.

Just because cats love veggies and grass, doesn’t mean they’re different and will be fine without meat. On a biological level, your cat requires animal-based foods. 

You personally might not have been considering putting your cat on a lettuce-only or plant-based diet. But it has to be said that lettuce and other veggies are only okay in small amounts and are not enough to sustain and nourish your cat on their own. 

The base and bulk of your cat’s diet needs to be a well-balanced, properly formulated cat food. Feeding them food specifically for cats is going to ensure that they get all of their basic nutrients every day. On top of this, you can add in cat safe veggies such as lettuce as a supplement and snack.

Is It OK for a Cat to Eat Lettuce?

In small amounts, lettuce can be a great low-calorie snack for your cat. It has many beneficial vitamins and nutrients, and can also help keep them well-hydrated. Like humans, cat love some variety in their diet and if you don’t give it to them, they might start looking elsewhere.

So it’s a good idea to find some healthy cat safe foods — such as lettuce — to incorporate into their diet. Just be sure that you aren’t depending on that alone to feed them, and you’re only using it as a supplemental snack to their cat food.
