Why does my cat go crazy for wheatgrass?

Cat owners know that our feline friends have some quirky preferences when it comes to food. One of the strangest is wheatgrass – that bright green grass grown from wheat berries that’s popular for juicing. Many cats go absolutely crazy for wheatgrass, chowing down on it like it’s catnip. But why do cats love this peculiar plant so much? As a cat owner and writer, I decided to dig into the science and myths behind this phenomenon.

The Nutritional Profile of Wheatgrass

There are several compelling theories behind why cats may love wheatgrass. One of the most popular hypotheses has to do with its nutritional makeup. Fresh wheatgrass contains a dense concentration of vitamins, minerals, and other nutrients. This includes:

Nutrient	Per 2 oz Wheatgrass	% Daily Value
Vitamin A	1214 IU	24%
Vitamin C	20 mg	33%
Iron	2.5 mg	14%
Calcium	11 mg	1%
Potassium	153 mg	4%

Cats are obligate carnivores, meaning they require certain nutrients found primarily in animal products. Taurine, for example, is an amino acid only found in meat that cats require to stay healthy. But cats still seem to benefit from the micronutrients found in plant foods as well. The vitamins, minerals, and antioxidants in wheatgrass may therefore be quite appealing to cats’ nutritional needs.

Chlorophyll as a Draw

Another popular theory is that cats are attracted to the high chlorophyll content in fresh wheatgrass. Chlorophyll is the green pigment in plants responsible for photosynthesis. It has a reputation as a “detoxifier” among humans who drink green juices and take chlorophyll supplements.

There isn’t much scientific evidence showing chlorophyll has detoxification powers. However, cats may instinctively be drawn to the green color, similar to how they are attracted to catnip. Some holistic veterinarians and cat experts theorize chlorophyll rich foods like wheatgrass provide antioxidant protection.

Simple Taste and Texture Appeal

There may also be a less scientific reason cats go nuts over wheatgrass. Some feline behavioral experts say cats just like the taste and texture!

Cats have a much stronger sense of smell than humans. Their taste buds also respond more strongly to bitter and sour flavors. Cats likely find the rich, earthy taste and aroma of wheatgrass pleasing. Its soft, pliable texture when fresh may appeal to cats’ senses and desire to munch on greens.

This theory helps explain why cats are choosy about the type of greens they enjoy. While wheatgrass tops the list, most cats have little interest in tougher dark greens like kale or collard greens. They seem to prefer tender, bright green vegetation similar to the leaves and grasses they would naturally eat in the wild.

The Instinct to Graze

Connected to taste and texture preferences, cats may view wheatgrass as an outlet for their innate need to graze. While domestic cats no longer hunt prey as their primary food source, they still retain those natural instincts, including the urge to nibble frequently throughout the day.

Cats are prone to pica, which is the practice of eating non-food items. Chewing houseplants, fabrics, and plastic are common pica behaviors in cats. Wheatgrass gives them a safe, edible outlet to satisfy the relentless drive to chew and graze.

Gut Health Support

Wheatgrass may support digestive health in cats, much like it does in humans. Since digestibility is closely tied to the taste and texture appeal, providing wheatgrass encourages eating more greens and fiber. The chlorophyll content may also have mild anti-inflammatory effects in the gut.

Anecdotally, some cat owners report their cats vomit less frequently after introducing wheatgrass. More research is needed to substantiate claims that wheatgrass improves digestion. But its nutrient profile combined with the grazing appeal makes it a safe supplement for better gut health.

Potential Risks of Wheatgrass for Cats

While wheatgrass has many benefits, there are a few potential downsides to be aware of before growing trays of cat grass. The main risks include:

• Mold exposure if grown incorrectly
• Pesticide residue contamination
• Gastrointestinal upset when consumed in large amounts
• Grass allergies in predisposed cats

To mitigate these risks, purchase organic wheatgrass and wheat berries from reputable sources. Grow them in sanitary conditions and harvest wheatgrass when it reaches 4-6 inches tall. Introduce wheatgrass gradually and monitor for any vomiting or diarrhea.

Cats with seasonal allergies may be sensitive to fresh cut grass. Observe for exacerbated allergy symptoms like itchy skin, ear inflammation, and sneezing.

How to Grow Wheatgrass for Cats

The easiest way to ensure your cat has a steady supply of wheatgrass is to grow it at home using wheat berries. Here is a simple step-by-step guide:

1. Purchase organic hard winter wheat berries, often sold for sprouting purposes.
2. Thoroughly rinse 1⁄4 cup wheat berries and soak in water overnight.
3. Drain the soaked wheat berries and spread evenly over a small tray or pot filled with potting mix.
4. Lightly cover wheat berries with another layer of potting mix.
5. Water thoroughly until drainage holes show moisture.
6. Place tray in a sunny area or under a grow light. Keep soil moist.
7. Grass should sprout within 5-7 days. Trim to 4 inches once it reaches 6 inches tall.
8. Continue watering and trimming wheatgrass as needed. Grow new trays every 1-2 weeks.

Cats can munch directly on live wheatgrass grown this way. You can also harvest and blend fresh wheatgrass into a paste to mix into their food.

Conclusion

When it comes to wheatgrass, cats’ cravings are likely based on its nutritional value, texture, and appeal to their natural grazing instincts. While too much can cause digestive upset, wheatgrass offers a beneficial source of nutrients and fiber. Homegrown organic wheatgrass provides the safest option for letting cats indulge in this quirky favorite.
