Cat Grass vs Wheat Grass: Which is Right for Your Cat?

Cats are fascinating creatures. As obligate carnivores, their digestive systems are designed to process animal protein. So, why do they sometimes munch on grass? While some cats eat grass when they’re unwell, others simply enjoy the taste and additional nutrients it provides. However, not all grasses are suitable for our feline friends. In this comprehensive guide, we’ll explore the differences between cat grass and wheat grass, their benefits, drawbacks, growing tips, and more. This will help you decide which option is best for your cat’s diet.

What is Cat Grass?

Cat grass encompasses various grasses that have grown from barley, rye, oat, or wheatgrass seeds. It’s important to note that cat grass is different from catnip, which is a member of the mint family. Unlike the grass in your yard, cat grass can be cultivated indoors in pots or trays, ensuring it’s free from poisonous pesticides and safe for your pets.

Pros and Cons of Cat Grass

Cat grass offers several benefits for your feline companion:

  1. Help with Digestion: Cat grass contains fiber, which aids in reducing hairballs and helps move hair through their digestive system. It can also help cats throw up other obstructions, such as excess bones or skin.

  2. Provide Nutrients: Cat grass is rich in vitamins and minerals, including vitamins A, B, and K, calcium, iron, and magnesium. These nutrients support your cat’s overall health and strengthen their immune system.

  3. Provide Mental Stimulation: Chewing on cat grass can relieve boredom and stress for many cats. This is particularly beneficial for indoor cats who may not have access to fresh vegetation.

  4. Prevent Destructive Behavior: Cats have a natural instinct to scratch and chew. Providing cat grass can redirect this behavior to a safe and acceptable outlet, reducing the risk of damage to houseplants or furniture.

However, there are a few cons to consider:

  1. Overeating: While cat grass is generally safe for cats, some cats may overeat and experience gastrointestinal upset, especially those with sensitive stomachs.

  2. Potential Intoxication: If the grass is contaminated with pesticides or other chemicals, there is a risk of intoxicating your pets. Opt for organic grass seeds and avoid using any chemicals when growing the grass.

What is Wheatgrass?

Wheatgrass is a type of cat grass that offers a range of benefits due to its high concentration of vitamins, minerals, and antioxidants. Despite its name, wheatgrass is harvested before the grain forms, making it gluten-free. It’s considered a versatile option and is safe for both cats and humans.

Pros and Cons of Wheatgrass

Wheatgrass shares many benefits with cat grass and offers some additional advantages:

  1. Joint Benefits: Wheatgrass is rich in vitamins A, B, and minerals that can help ease joint pain and discomfort in cats.

  2. Detoxification Support: Chlorophyll in wheatgrass acts as a natural detoxifier, improving overall health and potentially slowing down the aging process.

  3. Safe for Human Consumption: Wheatgrass is commonly consumed by humans in the form of juice or powder as part of a healthy diet or as a dietary supplement.

However, there are a few cons to be aware of:

  1. Potential Gastric Disorders for Kittens: Some kittens may develop gastric disorders if they nibble on wheatgrass, leading to health problems such as diarrhea and loss of appetite.

  2. Contamination Risks: Accidental ingestion of herbicides or other chemicals can be harmful to your cat’s health. Ensure you choose organic wheatgrass and introduce it gradually into your cat’s diet.

Wheatgrass Vs Cat Grass: The Differences

When comparing wheatgrass and cat grass, there are a few key differences to consider.

1. Taste and Texture

Cat grass has a slightly sweet and mild flavor, while wheatgrass tends to be a bit bitter and earthy. In terms of texture, cat grass like oat or barley is softer and more tender, making it easier for cats to chew and digest. On the other hand, wheatgrass is tougher and more fibrous, requiring closer supervision during consumption.

2. Uses

Cat grass is primarily grown for cat consumption, while wheatgrass can be enjoyed by both cats and humans. Wheatgrass is often added to the human diet in the form of juice or smoothies to improve digestion, boost the immune system, and enhance skin health.

3. Cost and Availability

Both cat grass and wheatgrass are widely available. You can find ready-grown grasses at pet stores or online retailers, usually priced below $10. If you prefer to grow them yourself, you can easily find cat grass or wheatgrass seeds at pet stores, online websites, or even garden centers.

Which is Better?

Choosing between wheatgrass and cat grass depends on your cat’s needs and preferences. Consider the following factors:

  1. Digestive Benefits: Both wheatgrass and cat grass offer digestive benefits for cats, providing additional fiber to their diets. Wheatgrass also supplements essential minerals and vitamins, making it a great choice if your cat is lacking these nutrients.

  2. Safety: Cat grass is specifically grown for cat consumption and is considered 100% safe. Wheatgrass leans more toward human consumption, so extra caution is advised. Choose organic wheatgrass and introduce it gradually into your cat’s diet.

  3. Preference: Cats may have a preference for the taste and texture of one type of grass over another. Offering both cat grass and wheatgrass can help you determine which your cat prefers.

  4. Availability and Cost: Consider availability and cost when making your decision. Ready-grown grasses are readily available, and growing them yourself is a cost-effective option.

Tips to Choose the Right Grass for Your Cat

  • Offer your cat different types of grasses to see which they prefer.
  • Look for organic, pesticide-free options to ensure your cat’s snack is healthy.
  • Avoid potentially toxic grasses, such as Bermuda grass or Kentucky bluegrass.

Growing and Caring Tips

Growing cat grass or wheatgrass is a simple process that requires minimal effort. Whether you choose ready-grown grasses or decide to grow them yourself, here are some tips:

  1. Growing Cat Grass: To grow cat grass, you’ll need seeds (wheatgrass, barley grass, etc.), organic potting soil, a plastic container, a spray bottle, and a cover (plastic wrap or newspaper).

  2. Step-by-Step Instructions: Soak the seeds in water overnight, discard the soaking liquid, and flush the seeds with clean water. Fill the container with potting soil, sprinkle the seeds evenly, cover with a wrap or newspaper, place in a bright location, and water lightly. Once the seeds sprout, remove the cover and water regularly. When the grass reaches 3-5 inches in height, it’s ready for your cat to enjoy.

  3. Tips for Care: Provide adequate light, keep the soil moist but not soggy, trim regularly to encourage new growth, and protect the grass from pests.
