Why do cats eat grass?

There are a few potential reasons why cats eat grass, including dietary benefits, its natural laxative effects and its ability to relieve an upset stomach. “Why does my cat eat grass?” As it turns out, most cats will eat grass from time to time, and there is no definitive answer as to why for one reason or another.  

House cats aren’t the only animals to engage in this behavior; wild cats and even their relative, the lion, have also been observed to graze on grass. Even though the grass is unpleasant to us humans, there are a few good reasons why your cat should eat it.

  • Cats eat Grass to Supplement their Diet

Grass juice contains folic acid, which is also found in their mother’s milk, and is an essential vitamin that aids in digestion, supports cell growth and produces red blood cells. Cats are sometimes drawn to eating grass in an attempt to counteract vitamin deficiency.  

If you’re worried this may be the case, it’s a good idea to reach out to your veterinarian to ensure your cat is getting complete and balanced cat food to support their everyday needs. 


  • Grass works as a Natural Laxative for Cats

Like people, cats can experience digestive discomfort from time to time. In these instances, cats sometimes eat grass to help them break down and pass things like fur from grooming to ease constipation. 


  • Grass Relieves Upset Stomach in Cats

You may be surprised to learn that cats are probably purposefully vomiting after eating grass if you’ve ever seen one in action. Cats can become ill from eating a lot of grass because they lack the enzymes needed to digest it. ​

Your cat will probably clear their stomach of other things like fur, feathers, parasites, or bones when they throw up, which can irritate the digestive tract or even result in more severe issues. 

Your cat will usually control how much grass it eats on its own. Keep your cat away from the grass if it has been fertilised or pesticide-treated. Instead, think about giving your cat indoor grass.


  • Some Cats Just Like Eating Grass

As many cat owners will tell you, there isn’t always an apparent rhyme or reason for some of their unusual behaviour. In some cases, cats eat grass simply because they enjoy it and might enjoy having a few more greens in their diet. 

If that’s the case, you can see if they like having vegetables like parsley or lettuce added to their daily meals. Another option is to feed your cat food with a higher fibre content. 


  • Is It Safe for Cats to Eat Grass?

As long as the grass hasn’t been treated with pesticides or herbicides, cats can consume it in moderation. But if your cat eats grass frequently, it might get stuck in its nasal passages and make them sneeze a lot. You must get in touch with your veterinarian right away to have it manually removed if this occurs. Grass can clog the digestive system as well.

Make sure all of your houseplants are non-toxic if your cat has a habit of munching on plants and grass. Certain popular houseplants can be toxic to cats, such as poinsettias and lilies. These two and several others are poisonous to cats and can cause a mild or severe reaction. 

If you want to ensure your cat is only eating grass that’s safe, you can purchase pots of grass, which will give your cat a personal patch to graze on. This will not only satisfy their need to nibble on grass, but it can also prevent them from chewing on your favourite houseplants.
