Best Cat Grass Kit for Indoor Cats: Our 6 Picks

The Cat Ladies Cat Grass Growing Kit 3 Pack

The Cat Ladies 3 pack includes three BPA free planters, three organic seed packets and three soil disks. You add water, put it in a bright window and grass sprouts in four to seven days. The seed mix is a blend of oat, wheat, rye and barley grasses that cats like.

It held a 4.5 star rating from over 27,000 ratings when we checked. The three pack means you can start a new container every week or two for continuous fresh grass. Organic and non GMO seeds are sourced locally in the USA.

ZESTIGREENS Self Watering Cat Grass Kit

The ZESTIGREENS kit uses a reusable self watering planter instead of disposable pots. You add water to the reservoir at the bottom and the grow mat stays moist without daily watering. It grows fresh grass in about five days with USA premium seeds.

The planter is reusable, so you only buy refill grow mats and seeds after the first kit. It held a 4.3 star rating when we checked. The soil free design is cleaner on countertops and windowsills.

Handy Pantry Organic Cat Grass Kit 3 Tray

The Handy Pantry kit includes three planting trays, three soil pucks and three packs of non GMO wheatgrass seed. It is a simple bulk option that grows a large tray of grass every time. The seeds are certified organic and the trays are reusable for refills.

It held a 4.5 star rating when we checked. The trays are larger than most cat specific kits, so they produce more grass per grow. Wheatgrass is the most popular single variety for cats.

The Cat Ladies Cat Grass Refill Kit 3 Pack

The Refill Kit gives you three organic seed packets and three coco coir soil disks without new containers. It is made to refill The Cat Ladies planters or any small pot you already own. This cuts the cost of repeated grows.

It held a 4.6 star rating when we checked. The seeds are the same organic mix as their full kit. Use any small planter, mug or tray about three to four inches deep.

ZESTIGREENS Wooden Planter Cat Grass Kit 3 Pack

The wooden planter set from ZESTIGREENS includes three small wooden planters, soil disks, organic seeds and mini gardening tools. It makes a nicer presentation for a windowsill and is a popular gift for cat owners.

It held a 4.4 star rating when we checked. The wooden planters are reusable for future grows. It takes about five to seven days to grow.

Cat Grass Kit with Biodegradable Pots 3 Pack

The PLANTMEW 3 pack uses eco friendly biodegradable fiber pots instead of plastic, plus soil disks and wheat and oat seeds. Grass grows in three to seven days with high germination rates.

It held a 4.4 star rating when we checked. The pots break down safely, making this a good low waste choice. It is one of the cheapest complete kits we found.

Why do indoor cats need cat grass?

Cat grass gives indoor cats a safe green plant to chew, helps move hairballs and provides a little extra fiber in the diet. It also gives them something to nibble that is not your houseplants, many of which are toxic to cats.

Grass is not a replacement for cat food. It is an occasional nibble that many cats enjoy a few times a week.

Benefit	What it does
Hairball support	Grass blades help cats cough up hairballs
Digestion	Small amounts of fiber can support gut movement
Safe chewing	Satisfies the urge to nibble plants
Enrichment	A fresh growing thing gives indoor cats interest

Keep toxic houseplants like lilies, pothos, snake plant and philodendron well out of reach even with grass available. For more ways to keep an indoor cat engaged, see our guide to how to keep an indoor cat happy.

How often should you give cats fresh cat grass?

Most cats nibble fresh grass a few times a week for five to ten minutes at a time. A single pot of grass lasts about two to three weeks before it wilts or gets eaten down. Stagger starts by planting a new pot every one to two weeks for continuous fresh grass.

• Place grass in a sunny window.
• Water lightly when the soil feels dry.
• Do not let cats pull the whole plant out by the roots.
• Replace when yellow or eaten down to soil.

Is cat grass the same as wheatgrass?

Most cat grass is wheatgrass, oat grass, barley grass, rye grass or a blend of those. Cat grass kits usually grow one or more of these cereal grasses, all of which are safe for cats. Wheatgrass is the most common single variety.

Avoid grass from outside lawns that may have been treated with fertilizer, weed killer or pesticides. Grow your own from a kit so you know what is in it. For calming support between meals, see our picks for the best cat calming diffuser and best cat calming diffuser for multiple cats.

Quick Buying Guide: How to Choose a Cat Grass Kit

• Size: Small pots fit on windowsills. Larger trays produce more grass for multi cat homes.
• Seed quality: Look for organic, non GMO seeds grown in the USA. Avoid seeds with added fertilizers or chemicals.
• Planter material: BPA free plastic is cheap and functional. Wooden or ceramic planters look nicer. Biodegradable pots reduce waste.
• Ease of growing: Kits with soil disks are the easiest. Self watering planters need less attention.
• Reusability: Some kits are one time use. Others have reusable trays or planters with refill packs.
• Growth time: Good kits sprout in four to seven days. If a kit takes more than ten days, seeds may be old.
• Safety: Do not buy kits with chemical fertilizers or pesticides. Plain seeds and soil are best.
