Organo Republic 16-Ounce Cat Grass Seed Mix
This four-grain blend contains barley, oats, rye, and wheat. The brand lists more than 20,800 non-GMO heirloom seeds and a tested germination rate of 90% or higher. Its resealable, waterproof bag is intended to protect seeds during storage, and a QR code links to growing instructions.
Best for: Cat owners who want several grass types in one larger bag and plan to plant more than once. The mix offers more grain variety than the single-wheat options. The product description presents cat grass as a natural treat and digestive aid, but it should not be treated as a veterinary remedy.
Limitation: The listing describes seeds and a growing guide, not a planter or growing medium. You will need to provide the planting setup.
Todd’s Seeds One-Pound Wheatgrass Seeds
Todd’s Seeds offers a one-pound bag of wheatgrass seeds. The product is intended for growing multiple trays and can be planted in a sprouting tray, planter pot, or DIY mason jar, according to the listing. The suggested routine is to soak the seeds, plant them, and mist them. The brand says growth can take about five days.
Best for: Buyers who want a large quantity of one grain for regular indoor or outdoor planting. Choose this if wheatgrass is the desired type and growing several batches matters more than having a mixed-grain seed blend.
Limitation: This is wheat-only, not a barley, oat, rye, and wheat mix. A tray or pot is not listed as included.
HOME GROWN Oat And Barley Cat Grass Seeds
This 16-ounce package combines oat and barley seeds. HOME GROWN describes the seeds as harvested in the United States and presents the resulting greens as suitable for cats as well as rabbits, guinea pigs, and hamsters. The product is positioned as a fresh supplement and a way to support natural foraging behavior.
Best for: Homes with cats and small pets that can eat these greens, or buyers who prefer an oat-and-barley combination. It offers two grain types without adding wheat or rye to the mix.
Limitation: The product details do not specify a germination rate or a growing timeline. Check the seed package for planting directions and confirm suitable foods with a veterinarian if your pet has dietary needs.
Back To The Roots Organic Wheatgrass Seeds
This one-pound bag contains wheatgrass seeds described as USDA certified organic and non-GMO. The brand says the seeds are not treated with pesticides and are suitable for people and pets. Its instructions call for soaking the seeds and watering once daily; the stated growing window is five to seven days.
Best for: Buyers specifically seeking organic wheatgrass seeds in a larger bag. The stated planting routine and timeframe make it a clear option for shoppers who want a product with growing guidance.
Limitation: This is a single-grain wheatgrass product, not a mixed cat grass seed blend. The product listing does not say that a planter or soil is included.
Organo Republic 4-Ounce Cat Grass Seed Mix
This smaller Organo Republic blend includes barley, oats, rye, and wheat. The listing states that it contains more than 5,200 non-GMO heirloom seeds and has a tested germination rate of 90% or higher. Like the larger bag, it comes in a resealable waterproof package and includes a QR code for online growing instructions.
Best for: First-time growers or buyers who want to try a four-grain mix before choosing a larger package. It has the same listed grain types and packaging features as the 16-ounce option in a smaller quantity.
Limitation: Its 4-ounce size means it contains less seed than the one-pound bags or the 16-ounce mix. No growing container is listed as included.
Buying Guide: How To Choose Bulk Cat Grass Seed
Should you choose a seed mix or one grain?
A mix is a fit for buyers who want several grain types from one package. The Organo Republic blends contain barley, oats, rye, and wheat; HOME GROWN combines oats and barley. A wheat-only bag, such as Todd’s Seeds or Back to the Roots, suits shoppers who specifically want wheatgrass and do not need a blend.
How much seed do you need?
For frequent planting, compare package weights: Todd’s Seeds and Back to the Roots each list one-pound bags, while Organo Republic offers 16-ounce and 4-ounce options. HOME GROWN is also 16 ounces. A smaller bag can be a practical starting point if you are unsure how often you will plant or how much your pet will eat.
What growing details matter?
Look for clear instructions, germination information, and storage features. Organo Republic lists a germination rate and a resealable bag. Todd’s Seeds describes soaking, planting, and misting; Back to the Roots gives a soak-and-water routine and a five-to-seven-day timeframe. Product details vary, so follow the package directions for the seeds you buy.
Do you need extra supplies?
These listings focus on seeds. They do not identify a planter or growing medium as included, so check the package details and prepare a suitable container and planting setup separately. Follow the seed instructions and keep the growing area accessible to your cat only when the grass is ready.
