Choosing the Best Cat Grass Buyer's Guide

Nobody wants to work so hard to get their houseplants lush and healthy only to have their cat eat them to stems. It’s also unhealthy for them. Many plants are poisonous, and in some cases fatal, to our feline companions.

A few cat enthusiasts devised cat grass to counteract this problem while also providing fiber to their regular diet. Is cat grass a miracle cure? You make the call.

What exactly is Cat Grass?

Cat grass is a blend of several grass seeds that grow inside in a container. To get the plant to sprout, all you need are seeds, soil, and sunlight.

It is often low-maintenance and simple to use. Many cat grass varieties are available as a starter kit or as individual seeds. While it may appear to be ordinary outdoor grass, this is not the case.

Outdoor grass can contain dangerous chemicals, pathogens, and other contaminants that your cat should avoid. Cat grass is completely safe for your cat.

What Is the Purpose of Cat Grass?

Cat grass can benefit your cats in a variety of ways.

Among the advantages are:

  • Intake of roughage in the diet
  • Hairball reduction
  • Keeps houseplants from being eaten
  • Vitamins and minerals are abundant.
  • A fantastic source of fiber
  • Cats regard it as a treat.
  • Chlorophyll helps to replace blood cells.
  • Removes foul breath

If you only provide cat grass for dietary benefits, it may not be much help in terms of nutrition. However, it is more preferable for your cat to eat nutritious greens rather than harmful ones.

Kit Varieties

When you decide to experiment with cat grass, you have a lot of options.

  • Self-Grow—self-grow kits are pre-assembled. You only need to add water.
  • Planting Kit—these kits must be assembled but include all necessary components.
  • Kit with Reusable Planter—each kit includes everything you need, as well as a reusable container.
  • Compostable—every aspect of the kit is biodegradable in these kits.
  • Kit + Toy—some vendors sell a block of cat grass along with a scratch post or toy to provide a multi-purpose cat station.
  • Bulk Seed contains only the seeds and nothing else. You can also purchase new seed packs or individual seeds. Experienced cat grass producers may already have a planter or two prepared with dirt. Cat grass seeds can also be purchased in quantity.

Cat Grass Varieties

Individual grasses or a mixture of grasses can be purchased.

The following are the most frequent types of cat grass:

  • Grass of Oats
  • Grass of Wheat
  • Grass of Rye
  • Grass of Barley

Many cat grass supplies include medlies of many seed types, whilst others only provide one. Read the label to see what each one has to offer.

Cats + Houseplants = Disaster

You know how it feels when your cat destroys one of your favorite plants. Apart from your aggressive cats destroying your greens, it can also have major health effects for them.

Even if certain plants are not dangerous, they might cause unpleasant side effects such as nausea, vomiting, and diarrhea.

If your cat starts eating plants or outdoor grass for no apparent reason, you should always take them to the vet to make sure there’s nothing else wrong.

Toxic Houseplants to Avoid

Here are some plants to keep your cat away from:

  • Jade
  • Lilies
  • Azaleas
  • Mistletoe
  • Tomato

A complete list of dangerous houseplants offered by Hills’ Pet Diet can be seen here. If you have specific plants, you may always look up its species to check if they are harmful to your indoor pets.

Keep an Eye on Your Cat’s Behavior

Most felines’ attempts to munch on plants may be natural behavior. It can, however, sometimes indicate a larger underlying health issue, such as a lack of nutrients in their diet.

If your cat starts eating plants out of nowhere, or if you notice them eating soil, it could be related to a deficit. It could also be due to gastrointestinal upset, which can be caused by a variety of illnesses you don’t want to neglect.

Growing Instructions for Cat Grass

Here are some pointers to help you get the most out of your cat grass purchase:

  • Each cat grass kit may require a distinct set of instructions, so read the product carefully.
  • Plant seeds in a deep container if possible. It can enhance the longevity of your cat grass if the grass’s roots can anchor down further.
  • Make sure not to overwater or submerge the cat grass. Overwatering can result in moldy soil and decaying grass roots, which can eventually destroy the plant. Underwatering can result in a drab area that browns or dies.
  • Your cat should not consume grass sprouts. Before inviting them to munch down, make sure your grass is 3-4 inches tall. Prematurely consuming the grass provides little nutritional advantage to your cat and hastens the plant’s demise.
  • Remember to give the grass as a reward. When your cat isn’t munching on the grass, keep it in a sunny spot to promote healthy development.
  • Various kits will require different measurements when it comes to watering your plant. However, as a general guideline, water your plant when the soil is dry to the touch.

Will Cat Grass Be Enjoyed By All Cats?

If your cat enjoys chewing on plants, there’s a good chance they’ll enjoy having cat grass nearby. But that doesn’t guarantee that all cats will be interested.

We’ve all seen how fussy cats can be about what they eat. If you give your cat its own cat grass, he or she may snub their nose and walk away.

Cat grass is usually the best option for cats who enjoy eating plants. If they haven’t, your cat grass purchase may be a bit of a gamble—left to your kitty’s judgment.

Do Cats Require Plants to Live?

The quick answer is no—cats do not require plants to survive. They are severe carnivores, which means they eat solely animal protein.

Because your cat’s sole dietary needs are meat and water, eating cat grass does not provide a significant nutritional advantage.

Most cats will regurgitate the grass instead of digesting it. Their bodies lack the enzymes required to break down plant-based substances. Cat grass simply adds fiber to the diet of cats who are prone to hairballs.

In short, the benefits are less nutritional, but they are preferable to consuming other dangerous plants.

Is there a difference between cat grass, catnip, and catmint?

Cat grass is not the same as catnip or catmint. Cat grass is a necessary common grass that contains no possibly dangerous chemicals or additives.

Catnip and catmint are both herbs in the mint family. Catmint has no mental shift impact on cats, whereas catnip does.


The Pet Greens Self Grow Garden Pet Grass is our favorite cat grass because of its ease of care, great production, and longevity. In terms of crisp greens, it has everything your cat could want.

But, if you want to get the most out of your cat grass investment, don’t overlook SmartyKat Sweet Greens Cat Grass. It’s exactly as nutritious and effective—and you save some money when you buy it.
