Wheatgrass is the young, tender shoot of the wheat plant, scientifically known as Triticum aestivum, harvested before the grain fully forms. Many cat owners wonder if this popular health food is appropriate for their feline companions, and the answer is yes, cats can and often do consume wheatgrass. This plant is a common choice for what is broadly marketed as “cat grass” because it satisfies a natural instinct in felines. While it may seem counterintuitive for an obligate carnivore to seek out vegetation, the consumption of wheatgrass serves several important functions for a cat’s overall well-being.
Is Wheat Grass Safe for Cats?
Wheatgrass is considered non-toxic and safe for felines to consume in moderation. Unlike many common household plants that pose a serious danger, wheatgrass is generally a healthy, non-poisonous option. This makes it an excellent, safe alternative for owners looking to redirect their cats from chewing on potentially harmful ornamental greenery.
The plant contains a variety of beneficial nutrients that can supplement a cat’s diet. It is a source of vitamins A, C, E, and K, B-complex vitamins, minerals like iron and magnesium, and chlorophyll. The high chlorophyll content supports general well-being and provides antioxidant properties. When harvested at a young stage, wheatgrass does not contain gluten, making it safe even for cats with sensitivities.
Why Cats Eat Grass
Mechanical Function
A primary reason cats instinctively consume grass relates to its mechanical function within the digestive system. Cats lack the specific enzymes required to break down plant matter, which is why eating grass often induces vomiting. This regurgitation is a purposeful action to clear the stomach of indigestible contents.
The fibrous blades of grass act as a binding agent, helping to sweep up material that cannot be passed through the digestive tract. This indigestible material typically includes hairballs, which accumulate during grooming, or bone fragments, feathers, and fur from prey consumed by their wild ancestors. By causing the cat to vomit, the grass helps to expel these potentially irritating or obstruction-causing items from the stomach.
Nutritional Benefits
Grass also offers a source of trace nutrients, most notably the B-vitamin folic acid (vitamin B9). This vitamin plays a role in the production of hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. Researchers speculate that felines may seek out grass to supplement their diet with this nutrient, as a deficiency in folic acid can contribute to anemia. The fiber in wheatgrass can also aid in promoting regular bowel movements, assisting cats who may be experiencing mild constipation.
Serving Wheat Grass Safely
To ensure safety, owners should always provide wheatgrass that is grown organically and is confirmed to be pesticide-free. Growing the grass at home from organic seeds is the most effective way to guarantee a clean, chemical-free source. Pre-grown pots of “cat grass,” which often contain wheatgrass, are also available at most pet stores and provide a ready-to-use option.
The best practice is to place the wheatgrass in an easily accessible location and allow the cat to self-regulate its consumption. Most cats will only nibble small amounts, which is considered moderate consumption. Owners should monitor their cat’s intake because consuming too much grass can lead to stomach upset, diarrhea, or excessive vomiting.
If a cat tends to overdo it, access can be limited to short intervals each day to prevent overconsumption. Occasional vomiting immediately after consumption is a normal part of the grass-eating behavior and is not necessarily a sign of illness. If vomiting becomes frequent or the cat shows other signs of distress, consult a veterinarian.
