Many cat people have observed that Cats eat grass and seem to enjoy doing so. Here we take a look at the different reasons why cats eat grass.
3 Reasons Cats Eat Grass
1) Grass juice contains folic acid that cats may crave – folic acid is an important vitamin that supports a cats’ growth and helps increase oxygen levels in their blood. If your cat is grazing on grass, it may be because they are battling a dietary deficiency and are in search of a folic acid vitamin boost.
2) Eating Grass provides for natural laxative benefits – Eating grass provides a source of fiber and helps your cat have regular bowel movements. This is especially important for cat digestive tracts that are sometimes clogged by fur (hairballs). Broad grasses seem to have the best laxative effect and narrow grasses appear to help a cat settle an upset stomach.
3) Grass in larger amounts relieves an upset stomach – Cats may eat a larger amount of grass to intentionally relieve an upset stomach. Eating a large portion of grass can help a cat to vomit and your cat is eating grass on purpose to cause this desired reaction. Cats don’t have the necessary enzymes to digest a large amount of grass, which is why eating a bigger portion of grass can make them sick. In the process of throwing up, your cat clears their stomach (e.g. of fur, feathers, parasites, bones, or other irritants) that upset their digestive tract or may even cause more lasting illness.
Cats will typically self-regulate the amount of grass they consume. If your cat has access to outdoor grass that has been treated with pesticides or fertilizers, then it is best to provide your cat with an indoor potted plant alternative that is safe grass to eat. Many specialty retailers and pet stores sell wheat grass or cat grass that is designed for safe in-home use for both humans and cats.

Many pet stores also carry “Cat Grass” or “Kitty Grass”. Cat grass is not a specific kind of plant, but a grass mixture that is grown from seeds, such as wheat, barley, oats or rye. Cat grass is grown indoors specifically for household pets.

If your cat eats large amounts of grass on a regular basis or wants to eat grass every day, consult your veterinarian as this may be a sign of other health issues.
