Before You Buy
Key Buying Factors
01
Seed Quality
Look for 100% organic, non-GMO seeds with high germination rates. Chemicals or fillers can harm cats.
02
Growing Medium
Soil or hydroponic? Soil kits often yield stronger plants; hydroponic may be cleaner but less nutrient-dense.
03
Container Size
A sturdy, non-toxic container that holds enough soil for root growth without tipping over.
04
Ease of Care
Minimal maintenance: water once or twice, indirect sunlight, and ready in a week. Mess-free designs preferred.
05
Value
Consider number of servings, seed quantity, and whether it’s a one-time kit or refillable.
06
Safety
No pesticides, coatings, or synthetic fertilizers. BPA-free plastic or biodegradable materials.
Living With It
Care, Cost and Maintenance
Watering
Keep soil moist but not soggy. Overwatering leads to mold. Mist lightly daily.
Light
Place in indirect sunlight. Too much direct sun can scorch; too little causes leggy growth.
Harvesting
Trim with scissors when grass is 4-6 inches tall. Cut close to base, leaving 1-2 inches for regrowth. Offer to your cat immediately.
Pro tip
Rotate two growing kits so one is always ready when your cat finishes the other. Cats love fresh grass, and continuous supply keeps them from nibbling houseplants.
Frequently asked questions
Is cat grass the same as catnip?
No. Cat grass is usually wheat, barley, oat, or rye grass-safe and digestible for cats. Catnip is a different plant (Nepeta cataria) that causes a euphoric response.
How long does a cat grass kit last?
With proper care, one planting can be harvested 2-3 times over 2-4 weeks. After that, the soil is depleted and you should start fresh.
Can I grow cat grass without soil?
Yes, using hydroponic kits with growth pads and water. However, soil-grown grass is often more nutritious and easier for beginners.
Will cat grass make my cat sick?
No, it’s safe and provides fiber. Some cats may vomit after eating large amounts-that’s normal and helps them expel hairballs.
How do I choose between seeds and a kit?
If you’re new, buy a complete kit with container and growing medium. For ongoing use, refill seeds are more economical.
