Is it OK to give cats lettuce?
With so many lettuce varieties out there, you are probably asking, ‘Can cats eat lettuce?’ And ‘Is it OK to give cats lettuce?’
The quick answer is yes; cats can eat lettuce.
It is perfectly safe for felines as a treat, and it can even provide some benefits.
There are multiple reasons to offer your cat lettuce:
- Preventing your cat from eating houseplants;
- Adding fiber to your cat’s diet;
- Offering a snack that doesn’t cause weight gain.
How much greenery can cats eat?
Can cats eat lettuce? Yes, but not just lettuce! A cat will never eat only greens.
Felines are obligate carnivores and cannot survive without meat.
Even if you are a convinced vegetarian, you shouldn’t try to make your cat a vegetarian too. A cat that doesn’t eat meat will die.
While feeding your cat lettuce is perfectly safe, you must not feed your cat lettuce only. Cats cannot get the nutrients they need from plant-based foods. Their biology makes it impossible. Your cat’s life and health depend on animal-based foods.
What greens can cats eat?
Even if you don’t offer your cat greenery, it may experiment with it. Many cats are known to nibble on grass. Others will attack your houseplants, which is bad for your plants.
It can also be bad for the kitty because some houseplants are toxic. 
Can cats eat lettuce? Yes, and other plants as well. 
Here are the safest and most beneficial plants your cat can eat:
- Bee balm
- Lemon balm
- Licorice root
- Dandelion root
Why some cats like eating plants?
Cats eat plants for multiple reasons:
- To help to remove non-digestible items like fur;
- Get relief from constipation due to the high content of fiber;
- Obtain nutrients such as folic acid, necessary for DNA production and maintaining blood oxygen levels within the optimal range;
- According to a hypothesis, to help them get rid of intestinal parasites such as worms. Greenery would physically scrub the walls of the gut and remove parasites;
- To have fun or to satisfy their curiosity.
Does your cat need lettuce?
Your can will be perfectly fine without lettuce. However, it does need a certain amount of greenery.
Lettuce is a good choice because it is harmless and accessible in most parts of the world.
If your cat’s food is of excellent quality, you can skip greenery. However, you cannot be sure that commercial food meets all the cat’s nutritional demands. The kitty will certainly not suffer by trying some lettuce or another safe plant.
It may even have some fun during the process!
Benefits of feeding lettuce as a snack
Have you decided to offer your cat lettuce? It is an excellent idea. Lettuce will provide the following benefits to your kitty:
- Supporting its weight loss plan
If your cat struggles to keep a healthy weight, snacks like lettuce will enable you to attain your goals.
One trick to prevent overfeeding is measuring out the food you want to offer your cat for the entire day. Even if the cat east multiple times a day, it will not exceed the limit. This method is easier than measuring out every meal separately.
- Complements dry food
Cats eating dry food only may have trouble staying hydrated. Lettuce can help as it contains approximately 95% water. Make sure your cat drinks enough water to prevent urinary tract infections.
- Preventing constipation
Having a sufficient amount of fiber in your diet helps you ‘go’ regularly. The same happens with pets. Lettuce will provide that amount of fiber needed to have regular bowel movements.
- Lettuce is packed with vitamins and nutrients
Not just humans need vitamins from plants in their diet but kitties too. Eating quality food can be sufficient, but a healthy snack certainly doesn’t hurt.
- Stimulating the cat
Experimenting with plants can keep your cat entertained while also getting some vital nutrients.
Some plants, such as catnip, can give them a drug-like euphoria. Snacking on lettuce is preferable to having your houseplants nibbled on.
- Adding variety to their diet
Cats need variety in their diet, just like people. Sometimes they can try things that are not edible. Lettuce, on the other hand, is perfectly safe to experiment with.
How can you make lettuce more attractive to cats?
Can cats eat lettuce? Yes.
Will they voluntarily eat it? Not all the time.
There are several tricks you can try to determine your cat to have lettuce or another healthy snack:
- Cutting lettuce into smaller pieces
Cats are notoriously picky eaters and may want to have food presented to them in a certain way. Giving large pieces of lettuce can result in a firm refusal. To make lettuce or greenery more appealing, cut it into small pieces or strips.
- Try multiple times
Cats often refuse new things. Consider offering greenery repeatedly before giving up.
- Try different varieties
Cats can refuse one type of lettuce for no apparent reason and love a variety with smaller or smoother leaves. Some pet owners have observed that their cats like varieties with darker leaves.
- Try different parts of the plant
Some kitties will prefer the leaves, while others may show more interest in the core.
- Put lettuce next to the cat’s food
Lettuce can be a weird object to your cat and not make it think about food at all. Placing a small piece of lettuce next to its food bowl can make the cat accept it.
What greenery is toxic to cats
Not all plants are safe for cats. Some are poisonous.
