11 Best Cat Grass to Buy, Benefits, Growing and Care

It is a fact that cats eat grass, some only nibble a few blades amount and occasional while others may munch a little a lot and more often. However, if your cat keeps on eating a lot of grass every day or regularly, you need to see your vet.

Why do cats eat grass or plant, what is cat grass, which best cat grass brands can I buy, how do I choose a great brand, and how do I grow and care for them? These are some of the concerns we intend to answer.

Why do cats eat grass

While the exact reason for cats eating plants, including grass is unclear, veterinarians, animal behaviorists, and researchers have given some explanations that include the following:

  1. To make them vomit – Some cats eat grass and vomit afterward, leading to the conclusion that they are trying to make themselves vomit to get rid of something terrible or inedible they have eaten. Whether it is the eating or the consequence of eating grass that makes them vomit is unclear. However, they don’t eat to make themselves sick just because they vomit.
  2. Help in digestion – Grass has fiber that may help keep things flowing in their stomach, break hairballs, settle stomach upsets, minimize effects of some GI disease, etcetera.
  3. Purge parasites – Some associate the behavior as a means to remove intestinal parasites, something their ancestors may have done.
  4. Nutritional deficiency – Perhaps some felines have unmet dietary needs like folic acid, chlorophyll, fiber, other vitamins, and minerals, and they are trying to get them in eating plants.
  5. Anxiety and stress – This behavior eating may be part of pica in cats, where they eat non-food material.
  6. Cats like grass – There may be a possibility that contrary to what we assume, kitties may love the taste and texture of greeneries.

These reasons are just but a summary, if you need in-depth coverage, see why cats eat grass and other plants and do cats like them.

What is cat grass

Cat grass refers to a blend of wheatgrass (Triticum aestivum), rye (Secale cereale), oats (Avena sativa), and barley (Hordeum vulgare, including the variegated Hordeum vulgare variegate) and sometimes flax (Linum usitatissimum) grass intended for cat grazing or eating.

However, at times, it may contain one a few or all these plants. Furthermore, some may have other plants, such as alfalfa or cat safe herbs.

Benefits of cat grass

As you can see, most of them are cereal grasses. They are safe, nutritious, may satisfy the plant-eating urge, and a good source of fiber, which may help reduce hairball, and support digestion,  

Also, it will help minimize the chances of your feline eating toxic house plants, those garden plants that may have herbicides or pesticides, or grown with harmful artificial fertilizers. Some of these plants can even kill your kitties.

Finally, if you buy cat grass, you will minimize the chances of your feline ingesting intestinal parasites like roundworms, hookworms while grazing in your lawn.

Choosing best grass kits for cats

A complete feline grass kit should have seeds, a growing container, and soil. We have given you the best brands in the market. If you still want to choose your kit, here is what to consider.

Know which cat grass type you need

As seen, there are various cat and kitten grasses, decide if you need a blend or just one of these types. Here is a brief description of each:

  1. Wheatgrass – rich in chlorophyll, minerals, and vitamin. It is the most popular type and most commonly available for sale.
  2. Ryegrass – has smaller blades but more durable, making it the right choice if you don’t want to replace your kitty grasses often.
  3. Barely – Grows longer, and nutrient-dense. Good for voracious eaters.
  4. Oats (Avena Sativa) – Sweet-tasting, rich in nutrients including proteins, iron, manganese, zinc, and B vitamins, and it may help aid digestion or calm digestive tract.
  5. Flax – Flax isn’t part of most kitty grasses blend. Its grass-like stalks have shorter leaves when thicken and grow more leave as they mature. Ensure they don’t grow over five inches, as it will be hard for these pets to eat them.
  6. Alfalfa – Unlike others, this legume is protein-rich and may help prevent kidney diseases, notes PetMD.

Look at the planter

There are many planter types such as decorative ceramic pots or wooden boxes, plastic tray, growing bags, and so on in various designs. Some are for single-use while others are reusable or refillable, and their prices vary too.

Ensure you choose one that is 100% safe, i.e., without PBA or any other harmful chemicals, including paints and finishing.

Finally, decide on whether you want one with drainage holes or not. They do help in preventing overwatering that may cause molds and root rot.

Choose organic soil growing substrate

Besides going for soil certified for organic farming, you have a choice of buying hydroponic growing media that doesn’t have soil such as coconut coir, vermiculite, perlite, and so on. Each has its advantages and disadvantages.

Finally, for those who want to grow cat grass without dirt, they will should buy grow stones, use filtered water and coffee filters. However, your feline may uproot your plants as it tries to eat them

Buy Organic and Non-GMO seeds

When buying seeds, choose 100% all-natural, i.e., non-GMO and certified USDA organic seeds as they will be the safest choice farmed without artificial fertilizers, herbicides, or pesticides and have not genetically modified. However, some non-certified are safe.

Number an age for your cats and kittens

Planters or growing containers come in various sizes, choose a bigger one if you have more than one cat. However, grow kitten grasses in smaller planters to make them more accessible.

How to grown cat grass indoors and outdoors

Once you have selected on the best brand, you will receive some straightforward growing and cat grass care tips. If you are using a growing container, here are typical growing steps:

  1. Fill soil ¾ way up the container or leave about an inch to two from the top and spritz or sprinkle with a spray bottle to dampen the soil. Don’t excessively soak or wet it as it will encourage molding if your planter doesn’t have drainage holes.
  2. Scatter your seeds, add about a ¼ an inch of soil on the seeds and dampen it again.
  3. Loosely cover the container with an unbleached paper towel, plant saucer, or plastic sauce to prevent drying and keep the planter in the dark place at ideal temperatures of 70ºF.
  4. Continue sprinkling water to ensure the topsoil doesn’t dry without soaking the soil, and after 3-7 days when they being to sprout, reduce the amount of water you use.
  5. Once they are an inch, remove the cover and take them to a place with light. They will require sunlight at least for a day in a week.
  6. Allow them to grow for another 10-14 weeks before allowing your kitties to graze directly from the container. A better way is to consider their height. Wait until they are about 10 centimeters (4 inches). Don’t cut the grass; just place it in their favorite corner or balcony.

If you are growing your cat grass outdoors, do so after spring when the worst weather is over. You will need to prepare the soil by removing any weeds and plants. The rest of the steps are more or less the same.

Finally, some people choose a smaller growing container and repot their grass once it has sprouted, which isn’t a bad idea if you know how to do it properly.

Cat grass care

There isn’t much care needed. You just need to keep the plants alive, just as you do to any other houseplants.

Too keep your grass alive, continue watering them using a spray bottle and giving them some time on sunlight and trip them to encourage growth. Don’t put too much water to avoid molding.

Secondly, once you notice wilting or change in color, it is time to plant new grass for your kitties.

Finally, if you want to use fertilizers, always go for organic ones only. Don’t use the normal ones used for regular farming.

Frequently asked questions

Does everyone need cat grass?

Yes. While it is vital for people with indoor cats that don’t have access to gardens or lawns to have cat grass, buy it even if your felines have access to barn, backyard, yard or garden.

If you don’t want to have them indoors, order seeds and plant them outdoor and designate the area for your cat’s grazing. We have already mentioned the benefits.

How much grass should my cat eat?

Give them a small amount, not more than 10% of their food intake, just as a treat. Ordinarily, feline munch green plants occasionally and they eat a small amount only as a treat. However, if your feline seems to have more appetite, it shouldn’t be more than 10% of their diet.

See your vet if your cat keeps eating a lot of grass every day, all the time, or often as may be due to underlying disease, and it can cause gastrointestinal blockages, nutritional deficiencies, among other issues.

Finally, to ensure your kitties always have something to eat, buy several planters, and keep rotating.

How long will cat grass last?

Typically, it will last 2-3 weeks, depending on the specific type. Some may be long-lasting than others. You will know it is time once they start having tough, rough leaves that are hard to chew with, some of them turning yellowish. Rotate your planter and plant new seeds.

Due to the short life-span, don’t buy already grown or sprouted grass. Instead, just buy the kit and grow them yourself.
