The Best Cat Grass

Sometimes you see a product’s name and you have no idea what that product is or what it does. That is most definitely not true with cat grass. Cat grass is a product whose name tells you exactly what it is: It is grass that is safe for cats to eat. People generally look to buy cat grass if their feline friends need something safe to chew on (as opposed to some houseplants that can be poisonous) or if they need a little digestive help as the grass can help a hairball exit the cat’s system.

We reviewed dozens of cat grasses to identify the best of the best. We looked for several different features in the cat grasses that we considered for this list. The grass needed to be completely organic and free of all pesticides and chemicals. It also needed to grow quickly so the cat would always have something to chew. Finally, we looked for the best in several different types of cat grass so that we could consider the specific taste preferences of different cats.

Best Cat Grass Overall: Todd’s Wheatgrass Seeds

There were so many reasons to love Todd’s Wheatgrass Seeds that it was easy to list them as our top pick. We loved that they are chemical-free and non-GMO. The last thing that you want in your cat grass is pesticides or other chemicals that, while they help the grass grow, are also harmful to your cat. Todd’s Wheatgrass Seeds produce grass that is safe for your cat to consume.

The seeds are also high-germinating seeds. If you’ve ever tried to grow something from a packet of seeds, then you likely know the disappointment of only getting one or two plants to grow out of the dozens of seeds that you toss into the ground. Todd’s Seeds are high-germinating seeds, which means that they are regularly tested to make sure a high number of them actually produce good and healthy grass. That’s good for your cat and good for your confidence in your gardening skills!

A special bonus that put this product over the top and secured their spot at number one on our list was that their laboratory is routinely tested for both germination rates and pathogens. They test the germination rates to make sure that the seeds are growing quickly. Because a pathogen is something that can spread bacteria or disease, it’s important that it’s not found in laboratories where the seeds are produced or it might infect the seeds. Todd’s Wheatgrass Seeds quickly and safely produce a beautiful and tasty grass that your cat will love to nibble.

Todd’s Wheatgrass Seeds Key Features:

  • Laboratory tested for pathogens
  • Chemical free
  • High germination rate

It’s important to know that a product does what it claims, and Priscilla’s results are verified and backed up by testing.

We also love that this particular blend of cat grass has so many different minerals and nutrients in it. Your cat needs certain vitamins and proteins throughout the day. It’s great when she can get them both from her regular food source and from her cat grass.

It’s important to note that although the picture shows a planter, this purchase is only the seeds. You’ll need to have your own container and your own soil. But no matter which pot you want to grow your grass in and which soil you choose to use, as long as you keep the soil exposed to sun and the seeds covered and moist, this cat grass blend should start sprouting in a few days. You will want to wait until it’s three to four inches tall for an optimal taste for your cat. But that should happen quickly and then your cat will have a good amount of grass to enjoy for weeks to come.

  • Blend of oat, wheat, rye, and barley

Who Should Buy Cat Grass

Cat grass is something that all cat owners should consider buying for their cats. There are lots of benefits to having cat grass for your pet and virtually no drawbacks, save for some cats who just don’t have an interest in nibbling on the grass. You should especially consider cat grass if your cat falls into one of the following three categories.

  1. She needs a safe plant to chew on. If your cat has shown curiosity about your houseplants or you’ve even caught her trying to nibble one, you should definitely buy cat grass. Many houseplants can be poisonous for cats, so giving your feline friend cat grass may help to steer her away from the dangerous plants by giving her a safe patch of greenery to eat.
  2. She needs a little digestive help. Because the properties of grass can help aid a cat’s digestive system (help her push out a hairball, help her vomit something that’s upsetting her stomach, etc.), it’s great to have around the house. It might be a natural remedy where you would otherwise need to use medicine.
  3. She needs a distraction from chewing household items that she shouldn’t be chewing. If your cat loves to chew your furniture, the curtains, her cat bed, or anything else that she shouldn’t be chewing, cat grass may give her something safe and soothing to chew on that won’t get her into trouble or harm her.

Important Features to Consider

Cat grass should have a few important features. Here’s what to consider when selecting cat grass:

  • Seeds should be organic. You want to make sure that the grass you grow for your cat is organic. That means it’s free of all pesticides and chemicals that might be used to grow the grass you find on your lawn. All nutrients should come from the seed, the soil, and the water.
  • Seeds come in a resealable bag. If you buy your cat grass seeds in bulk, you want to make sure that they come in a resealable bag. This will ensure that they’re still fresh when you go to plant them.
  • Quick germination. This means that it doesn’t take long for the seeds to take root in the soil and sprout. For your first batch, germination speed isn’t as critical. However, for follow-up batches, you want to make sure they will grow quickly because you don’t want your cat to be without the grass that he’s used to having.
  • Seeds should be non-GMO. Non-GMO means non-genetically modified. Well, what does that mean? Good question. Seeds that are non-GMO are basically the same seeds that have been around for decades or even centuries with no scientific intervention. Seeds that are genetically modified are ones whose DNA has been altered by scientists for a variety of reasons. Per this article on GMO seeds, there are only ten different crops that are approved for genetic modification in the United States, and cat grass (or regular grass) isn’t one of them.

Frequently Asked Questions

What is cat grass?

As we’ve said, cat grass is grass that is safe for cats to eat. It’s grown from an assortment of seeds that include, but are not limited to, oats, barley, wheat, and rye. Most are meant to be grown indoors, but some can tolerate the outdoors as well. It’s grown in small patches for your cat to nibble on as a safe alternative to your lawn (which may contain pesticides) or other houseplants (many of which may be poisonous).

What are the benefits of cat grass?

There are several benefits to having cat grass available for your feline.

  1. As we mentioned above, it may prove to be a healthy and safe distraction from other plants that are not safe for cats to eat. Give your cat something good to chew on so he doesn’t eat the stuff he shouldn’t.
  2. Cat grass may help ease a sensitive digestive system. Among other ways it helps, cat grass contains a natural laxative that can help push a hairball out of her system.
  3. Because it contains nutrients like vitamin B and niacin, cat grass will give your cat a little bit of extra nutrition.
  4. When dogs chew and swallow grass, it’s often a sign that they need to throw up as the grass helps them to vomit. For cats, it’s the same thing. A little bit of grass may help them throw up if something isn’t sitting right in their system.

Should you trim cat grass?

Opinions are divided on this one. Some say yes, you should trim cat grass down to about one inch every couple of weeks to help aid in the growth of new grass. Others say to let it go until it wilts and then just plant new grass. It grows quickly and easily, so don’t be afraid to plant several pots on staggered days. That will ensure that as one pot of grass dies (as all inevitably will whether you trim or not), you always have at least one more ready for your cat.

Why does cat grass die so quickly?

Generally speaking, you grow cat grass in a small container. After all, the goal is to give your cat a small amount to nibble on not move your entire lawn indoors. Consequently, because the grass is planted in small pots, it becomes rootbound very quickly. “Rootbound” means that the roots are too long for the cup and the plant’s root basically strangle the plant because they have nowhere to grow. You can always plant new grass (it’s relatively inexpensive and grows quickly) or you can replant your grass into a bigger pot to give it more room to grow.
