Why Your Cat Needs Grass Indoors

Cats are curious creatures with a fascinating set of instincts, even those who have never set paw outside. One of these instincts is to consume grass. In the wild, cats eat grass for several reasons, and it’s important to understand these benefits to appreciate why offering indoor grass is so beneficial for our domesticated felines.

Digestive Aid: Grass acts as a natural laxative for cats. It can help them pass indigestible materials like fur (from grooming) or feathers and bones (if they were outdoor hunters). It can help move things through their digestive tract, reducing the likelihood of hairballs becoming a major problem.
Nutritional Boost: While cats are carnivores, young grasses contain essential nutrients like folic acid (a B vitamin important for growth and metabolism) and chlorophyll. While their primary diet should be high-quality cat food, these added nutrients can offer a supplementary boost.
Inducing Vomiting: Sometimes, cats eat grass to intentionally vomit. This can help them clear their stomachs of anything that might be bothering them, like ingested hair or toys that are too large to pass. It’s a natural way for them to self-medicate.
Stress Relief and Enrichment: For indoor cats, a patch of fresh, juicy grass can provide mental stimulation and a sense of connection to their wilder ancestors. Chewing on grass can be a relaxing activity, offering a welcome distraction and a bit of natural fun.
Preventing Houseplant Damage: If your cat has a taste for your beloved POTHOS or your delicate ferns, providing them with their own, safe, and appealing grass option can redirect their chewing habits. It’s a win-win: your plants are safe, and your cat gets their craving satisfied.

Choosing the Right Grass for Your Cat

Not all grass is created equal, and for your cat’s safety and enjoyment, it’s crucial to select the right types of grass. Some common grasses can be toxic to cats, so sticking to ornamental or specifically cultivated varieties is key. When you’re shopping for cat grass, you’ll typically find it available in two main forms: seeds or pre-grown mats.

Common Types of Cat Grass

The most popular and safest options for indoor cats are usually varieties of wheat, barley, oats, or rye. These are generally non-toxic and palatable for cats.

Wheatgrass: This is the most common and arguably the best all-around choice. It’s packed with nutrients, easy to grow, and cats typically love its flavor and texture.
Barley Grass: Similar to wheatgrass, barley grass is highly nutritious and easy for cats to digest. It can be a great alternative if your cat seems less keen on wheat.
Oat Grass: Another excellent choice, oat grass is soft, palatable, and rich in vitamins and minerals. It grows quickly and is very resilient.
Rye Grass: You might see rye grass mentioned, but be sure to differentiate between perennial ryegrass (which can be less digestible and hard on some cats’ systems) and annual ryegrass (Italian ryegrass), which is often used in cat grass seed mixes and is generally considered safe. For simplicity, sticking to wheat, barley, or oat varieties is often the easiest path for beginners.

What to AVOID

It’s critically important to know which plants are toxic to cats. Many common houseplants and outdoor grasses can cause severe illness or even death. Always err on the side of caution. The ASPCA has an extensive database of toxic and non-toxic plants that is an invaluable resource for any pet owner:

When in doubt, do not let your cat ingest it. Avoid ornamental grasses of unknown origin, certain types of lilies, daffodil bulbs, and many common houseplants like Pothos or Dieffenbachia.

Getting Started: Growing Your Own Cat Grass

Growing cat grass at home is a straightforward and incredibly rewarding DIY project. You have two main paths: growing from seed or purchasing a pre-grown mat. Growing from seed is usually more economical and allows you to control the process entirely.

Method 1: Growing Cat Grass from Seed

This is the most popular and cost-effective method. You’ll only need a few essential supplies to get started.

Supplies You’ll Need:

Cat Grass Seed Mix: Look for mixes specifically labeled for cats, usually containing wheat, barley, oat, and/or rye seeds. You can find these at pet stores, garden centers, or online.
Potting Container: Any small to medium-sized pot with drainage holes will work. Terra cotta, plastic, or even recycled containers are fine. A shallow, wide container is often best so your cat has plenty of surface area to graze.
Potting Soil: Use a good quality, sterile potting mix. Avoid soil from your garden, as it can contain pests, diseases, or fertilizers that may be harmful to your cat.
Watering Can or Spray Bottle: For gentle watering.
Sunny Spot: Cats don’t just enjoy grass; they also enjoy the sunlight!

Step-by-Step Planting Guide:

Prepare the Pot: Ensure your chosen container has drainage holes. If it doesn’t, you’ll need to drill some or choose a different pot.
Add Potting Soil: Fill the container with potting soil, leaving about an inch of space from the rim.
Sow the Seeds: Spread a generous layer of cat grass seeds over the soil surface. Don’t be shy – a dense planting leads to a lush patch of grass. Some gardeners recommend pressing the seeds gently into the soil to ensure good contact.
Cover Lightly: Lightly cover the seeds with a thin layer of soil, about 1/4 inch deep. Or, for a very simple approach, you can skip this step and just press them into the soil firmly.
Water Gently: Moisten the soil thoroughly using a watering can with a fine rose or a spray bottle. You want the soil to be damp, not waterlogged. Overwatering can cause seeds to rot.
Create Humid Conditions (Optional but Recommended): To encourage germination, you can cover the pot loosely with plastic wrap or place it inside a large plastic bag. This helps retain moisture and warmth. Remove the cover as soon as you see seedlings sprouting.
Find a Sunny Spot: Place the pot in a location that receives at least 4-6 hours of sunlight per day. A windowsill is often ideal.
Water Regularly: Keep the soil consistently moist but not soggy. Check daily and mist or water gently as needed.
Watch it Grow!: Your cat grass should sprout within 3-7 days. It will be ready for your cat to enjoy in about 1-2 weeks, typically when it’s 2-4 inches tall.

Method 2: Purchasing Pre-Grown Cat Grass Mats

If you’re looking for an instant solution or prefer not to deal with planting, pre-grown cat grass mats are readily available.

Where to Find Them:

Pet supply stores (physical and online)
Some grocery stores (often in the produce or pet sections)
Online retailers like Amazon, Chewy, etc.

Pros of Pre-Grown Mats:

Instant Gratification: Your cat can enjoy fresh grass immediately.
Convenience: No planting, soil, or waiting required.
Cleanliness: Less mess associated with soil for some owners.

Cons of Pre-Grown Mats:

Cost: Can be more expensive than growing from seed, especially if you need frequent replacements.
Lifespan: They don’t last as long as a homemade patch and eventually wither.
Limited Variety: You typically have less control over the type of grass.

When you buy a pre-grown mat, simply place it in a suitable spot for your cat. Some mats come with a disposable tray; others might require you to place them in a shallow dish to catch excess water. Keep them watered according to the product’s instructions.

Caring for Your Cat Grass

Once your cat grass is planted and growing – or if you bought a ready-made mat – a little ongoing care will keep it healthy and appealing for your feline friend.

Watering Needs

The key is to keep the soil moist but not waterlogged. Overwatering can lead to root rot and mold, which isn’t good for your cat or the grass. Underwatering will cause the grass to dry out and die.

For seedlings: Mist gently daily or every other day, especially if the air is dry.
For established grass: Water from the bottom if possible by placing the pot in a tray of water for about 15-20 minutes, allowing the soil to absorb moisture from below. This prevents the leaves from getting waterlogged and reduces the risk of fungal issues. Alternatively, water very gently at the base of the plant.

Sunlight Requirements

Cat grass, like most plants, needs sunlight to thrive. A bright, sunny windowsill is perfect. Aim for at least 4-6 hours of indirect sunlight daily. If you don’t have a very sunny spot, consider using a small grow light to supplement natural light, especially during winter months or in darker apartments.

Pest and Disease Watch

Because you’re using sterile potting mix and fresh seeds, pest problems are usually minimal. However, keep an eye out for common houseplant pests like spider mites or fungus gnats. If you do notice issues:

Fungus Gnats: These tiny flies are attracted to overly wet soil. Allow the soil surface to dry out slightly between waterings. You can also use sticky traps.
Spider Mites: Increase humidity, and wash the leaves with a gentle soap-and-water solution, rinsing thoroughly.

If you ever spot mold or mildew on the grass or soil, remove the affected parts immediately and ensure the pot has good drainage and airflow. Never use chemical pesticides or fungicides on grass intended for your cat.

Trimming and Rotation

As your cat grass grows, you can trim it to keep it tidy and encourage bushier growth. Use clean scissors to snip off blades about an inch from the soil. This also makes it easier for your cat to access and chew without pulling up the roots.

Cat grass patches don’t last forever. Typically, a patch will remain productive for 2-3 weeks. Once it starts to look yellow, sparse, or unappealing, it’s time to discard the old patch (compost it if you can!) and plant a new one. Having a second pot ready to go ensures your cat always has a fresh supply.

Introducing Your Cat to Their New Snack

Some cats will dive right in, while others might be a little hesitant. Here are some tips to help your feline friend discover their new, tasty treat:

Placement is Key: Place the pot in a location your cat frequents or enjoys lounging in. A quiet corner, a sunny spot, or near their favorite napping place can work well.
Gentle Introduction: Don’t force your cat to interact with the grass. Simply place the pot where they can see and smell it.
Encourage Exploration: You can try gently rubbing a few blades between your fingers to release their aroma. Some cats respond to the scent.
Playful Interaction: If your cat is playful, you might try dangling a blade (gently!) near them, like a toy.
Observe Their Behavior: Watch how your cat eats. Some will nibble delicately, others will munch enthusiastically. Both are normal!
Supplement, Don’t Replace: Remember, this is a supplement to their balanced diet, not a replacement for high-quality cat food.

Troubleshooting Common Cat Grass Issues

Even with the best intentions, you might encounter a few hiccups. Here’s how to navigate them:

Grass is yellowing or dying: This is often due to watering issues. Check if the soil is too dry or too waterlogged. Insufficient sunlight can also be a cause; try moving the pot to a brighter location or supplementing with a grow light.
Seeds are not germinating: Ensure the seeds are fresh (check the expiration date if possible). Make sure the soil is consistently moist. Sometimes, simply waiting a few more days can do the trick, as germination rates can vary.
Mold or Fungus: This usually means the soil is staying too wet, or there isn’t enough airflow. Remove any visible moldy patches, allow the soil to dry out a bit more between waterings, and ensure good ventilation around the pot.
Cat ignores the grass: This can happen! Try different types of cat grass seeds, or a pre-grown mat. Sometimes, cats just aren’t interested. You can also try different placement.
Overgrown grass: Trim it! Cutting the grass back to about an inch from the soil will encourage new, tender growth and make it more appealing.
