The Best Cat Grass Seeds & Kits To Buy

Many cat owners have difficulty stopping their cats from destroying their houseplants.

Cats have a tendency to nibble on grass, or anything green for that matter, to enrich their diet with essential nutrients, help digestion, and minimize hairballs.

Many cat owners may be tempted to allow their cat to go outdoors and eat grass from the yard, but many people use chemicals and pesticides in their yards, which can make your cat ill or even kill it.

The good news is that you may grow your own grass for your cat without using pesticides or other chemicals.

BestForPets (bestforpets.org) has reviews of the %product_count% best cat grass seeds and kits in %year% for you, whether you're just searching for cat grass seed or a full kit to get you started.

Once the water has been absorbed by the soil, remove about a teaspoon of soil from each compartment, add the seeds, and then replace the lids.

You’ll see sprouts in a few days, and before you know it, you’ll have a planter full of grass for your cat. This package includes a stylish wood box that is heavy enough to discourage cats from knocking it over or ripping the cat grass out.

This is not the ideal option for a large planter to grow cat grass because it is a small container. Because the container is lightweight, your cat may tip it over or pull the grass out of the shallow pot.

The bags are tall, and if you do not allow the grass to grow tall enough past the top edge of the bag, your cat may have difficulty eating it.

  • Simple to cultivate
  • Plantings can be placed apart to ensure that there is always new grass.


  • Bags that are lightweight

Buyer's Guide: How to Choose The Best Cat Grass Seeds and

What Exactly Is Cat Grass?

Cat grass is a type of grass seed that may be grown indoors in a pot or other growing container to help satisfy your cat’s demand for greenery.

Wheatgrass is the most popular grass for cats, but you can also purchase oat, barley, rye, and flax seeds on their own or in blends.

Some cats prefer only one type of grass, while others enjoy a mix of several. When you first start cultivating cat grass, it will most likely take some trial and error to figure out what your cat prefers to eat.

We recommend starting with one of the smaller kits to avoid wasting money on a huge kit that contains grass that your cat will not eat.

Once you’ve determined what your cat prefers, you can buy seed or a larger kit to develop their new favorite treat.

What Are the Advantages of Cat Grass?

Cat grass is a supplemental food that is added to cats’ meals to help them digest. Grass is high in fiber and adds roughage to their diet.

It contains a variety of vitamins and minerals, as well as chlorophyll, which aids in the replenishment of blood cells. It also helps to reduce hairballs in cats and can even assist to freshen your cat’s breath.

Cats consider grass to be a delectable treat, and growing some in your home will help keep them from eating your houseplants, some of which are harmful to cats.

Selecting the Best Cat Grass Seeds and Kits

Cats like munching on tasty cat grass, but there are a few things to consider before purchasing seed or a grass growing kit. Cat grass can be grown in a variety of ways.

The following are the options:

  • Planting Kits – These kits often include seeds, soil, and a container in which to plant your grass. They could come with a single-use container or reusable planters.
  • Self-growing Kits Open the packet, fill it with water, and watch your seeds sprout. These kits are ideal for beginners or individuals with weak hands.
  • Quantity Seeds – Cat owners with grass growing experience may prefer to save money by purchasing their cat’s favorite grass seed in bulk. To use bulk seed, you will need your own soil and planters.
  • Live Plants – This is the simplest choice because you can buy live cat grass from a store or online. The grass is delivered right to your home, and all you have to do is leave it out for your cat to consume.

Growing Cat Grass Suggestions

There are numerous kits and seeds available for cat owners who want to cultivate their own grass.

Here are a few pointers to get you started on your grass-growing journey:

  • Read the instructions carefully before attempting to grow your seeds, whether you are planting them yourself or using a kit.
  • Understanding how seeds germinate is critical to success. To sprout effectively, certain seeds must be wrapped in damp paper towels and placed in a dark, humid environment. Determine the type of seeds you have and make plans accordingly.
  • Plant your seeds in a container deep enough for the grass roots to take hold. Cat grass planted in a shallow container will not endure as long as cat grass put in a deeper container with plenty of area for the roots to spread.
  • Take cautious not to overwater or submerge your cat grass. Overwatering causes root rot and mold. Underwatering stunts growth and causes yellow grass. Check the instructions on your kit or seed packet to ensure you give the seeds the exact amount of water they require to maintain your grass healthy.
  • If you buy live plants, make sure to submerge the containers in at least an inch of water for around an hour 1-2 times per day. The grass roots will reach for the water and absorb what they require. This will keep your grass from turning yellow and your plants from dying.
  • Cat grass is delicious. If your cat isn’t used to grass, make sure it doesn’t eat too much and become ill.
  • To encourage growth, keep the grass in a sunny location and remember to water it according to the package guidelines.


The SmartCat Kitty’s Garden is our top overall recommendation, as it provides a variety of cat grasses in a robust container that your cat will have difficulty knocking over.

If you’re not sure if your cat likes grass, we recommend getting the SmartyKat Sweet Greens Cat Grass Seed Kit since the low price gives you the most value while you figure out if your cat likes their new treat.

The Cat Ladies Cat Grass Kit & Decorative Wood Planter is our top pick since it includes a range of decorative planters in which you may choose one to fit your décor.
