Cat grass kit

Let’s face it, cats are picky eaters. And while it’s certainly cute when they meow at you when they want more food, it’s not so cute when they start munching on your houseplants.

With a cat grass kit, you can grow your own grass to ensure your furry pal gets all the vitamins and minerals for healthy growth while providing them with something to chew on and explore.

These kits come with everything you need: seeds, soil pellets, water crystals, and an instruction manual that helps ensure you’ll get a healthy patch of delicious grass. But with all the options in the market, it can be hard to find a good option for feeding your pet. To help you out, we’ve put together a list of some of our favorite cat grass kits for 2025.

Buying Guide: Cat Grass Kit

Benefits of Cat Grass

Cat grass is a wonderful addition to your cat’s diet. It contains many of the nutrients cats need for optimal health, including vitamins A and K, iron, calcium, and magnesium. This grass also provides fiber and chlorophyll, which helps remove toxins from your cat’s body that could lead to different diseases, including arthritis and diabetes.

Here are some of the benefits of cat grass for your feline friend:

  • Strengthens the immune system to fight off allergies.
  • Helps reduce the risk of cancer.
  • Supports healthy kidneys and urinary tract function.
  • Prevents hairballs by providing roughage.
  • Reduces diarrhea, constipation, and flatulence.

Different Types of Cat Grass Kits

Planting kit

This type of kit comes with everything you need to grow cat grass, including seeds, soil, fertilizer, and a pot or tray to plant the seeds in. You can even reuse the pot or tray for growing different plants.

Self grow kits

These are similar to planting kits, except they don’t require any gardening knowledge or experience. They come with all the materials required, so all you need to do is follow the instructions and add water every few days until you have a healthy crop of cat grass ready for your pet!

Biodegradable kits

These types of kits are made with pet-safe materials and are compostable. They typically come with seeds and soil that can be planted in a pot or directly in the ground. The seeds sprout quickly and grow for about two months before dying off naturally.

The good news is that these kits do not require any maintenance once they’re set up, so you don’t have to worry about taking care of the plants or weeding them now and then!

Pre-grown grass kit

Pre-grown cat grass kits consist of pre-grown plants that have been harvested from gardens around the world and then shipped directly to your door for planting in pots. With these kits, you’ll also receive instructions on how to care for these plants and keep them healthy as they grow bigger over time.

How To Choose a Cat Grass Kit

Seed quality

Cat grass kits come with seeds that vary in quality and germination rate. The lowest-quality seeds take longer to grow, while higher-quality seeds will grow quickly and produce more cat grass per package. For maximum health safety, look for a company that only sells organic, non-GMO seeds that are pesticide-free.

Included accessories

The kit should come with everything you need to get started right away, including potting mix (preferably organic), stakes for hanging your pots, seeds, and compost. Many kits also include planting trays so you don’t have to buy them separately.

Composition

Cat grass kits come in different compositions including wheatgrass and barley grass or a combination of different types of grasses, such as wheatgrass, barley grass, ryegrass, and oat grass. That said, some companies sell single types of grasses, which can be more expensive but may be easier to maintain over time. For maximum nutritional value, it’s recommended that you use a combination of all four types of grasses.

People Also Asked

For how long does cat grass last?

It depends on how much your cats eat and how often. On average, cat grass lasts for about two to three months.

Can cat grass cause diarrhea?

Cat grass does not cause diarrhea, but it can be a little hard on their stomachs if they consume too much of it at once.

Is cat grass safe for kittens?

Yes, but only if they are old enough (at least eight weeks) and are not aggressive chewers. Younger kittens may develop teeth problems from chewing on the grass too much, so you have to be careful!

How do I grow cat grass indoors?

There are a few things you need to get started growing cat grass indoors. You'll need a pot or container, some soil, and cat grass seeds.

  1. Fill your pot or container with soil. Be sure to choose a pot with drainage holes to prevent pooling.
  2. Sow the cat grass seeds in the soil and cover them with a thin layer of soil.
  3. Water the seeds lightly and keep them moist until they germinate, which should take about a week.
  4. Once the seeds have germinated, move them to a location with plenty of sunlight. Keep the soil moist but not wet. 
  5. In about five to seven days, your cat grass will be ready to be nibbled on!
