A bag of dried catnip from the pet store loses its punch after a few weeks. The volatile oil that drives cats wild—nepetalactone—degrades fast once the leaves are crushed and exposed to air. A proper catnip growing kit bypasses that problem entirely by putting a live, thriving plant on your windowsill, ready to be snipped fresh whenever your feline demands it.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years analyzing grow-kit formulations, seed-germination data, and owner-verified outcomes across dozens of indoor gardening setups to separate the kits that actually produce vigorous plants from the ones that fizzle out after one watering.
Whether you need a compact solution for a small apartment or a premium planter that doubles as decor, this guide breaks down the best options on the market today. Each recommendation is based on real germination rates, soil quality, and owner feedback so you can confidently pick the best catnip growing kit for your home.
How To Choose The Best Catnip Growing Kit
Not all growing kits are equal. Some pack high-germination heirloom seeds with nutrient-rich soil, while others skimp on seed viability and leave you staring at empty pots. Here’s what separates a thriving catnip setup from a disappointing one.
Seed Quality and Germination Rate
Catnip seeds are small but tough. Look for kits that explicitly state a non-GMO or heirloom seed source, and ideally a germination rate above 90%. Sealed packaging that protects the seeds from moisture and temperature swings during storage also matters. Cheap kits often use old or improperly stored seeds that struggle to sprout, wasting your time and patience.
Container Design and Drainage
Catnip hates soggy roots. A kit with drainage holes at the bottom of the planter is vastly preferable to one without, because standing water encourages mold and root rot. If the container lacks drainage, you must water with extreme caution. Premium kits often include a separate tray or saucer to catch excess water without soaking the base.
Soil Composition and Nutrient Content
The soil discs or pellets in the kit should be light, well-aerated, and rich in organic matter. Coconut coir or peat-based mixes work well because they hold moisture without becoming waterlogged. Avoid kits that provide only a thin layer of generic potting soil—catnip is a vigorous grower that needs enough depth for its taproot to develop.
Included Bonus Components
Extra seeds, mini gardening tools, and plant markers are nice touches, but don’t let flashy add-ons distract from the core growing components. A kit with a single high-quality seed packet and good soil beats one with five mediocre seed packets and a flimsy plastic trowel every time. Prioritize germination science over gimmicks.

In‑Depth Reviews
1. HOME GROWN Herb Garden Planter Indoor Kit
This all-in-one herb starter kit from HOME GROWN delivers everything needed to grow basil, catnip, and more in a compact indoor setup. The package includes four durable pots, nutrient-rich peat soil discs, four heirloom seed packets, and a full gardening tool set with a spade, shovel, rake, shears, tweezers, clippers, wire, and plant supports. The peat soil expands nicely to fill each pot, giving seedlings enough depth to establish strong roots right from the start.
Owner feedback consistently highlights the easy-to-follow instructions and high germination rate across multiple herb varieties. One reviewer noted all plants were visible and healthy after two weeks, while another praised the extra seeds included for replanting if a batch fails. The beige planter color and multi-pot design make it unobtrusive on a kitchen windowsill, and the included tools eliminate the need for any separate purchases.
On the downside, the basil seeds in some kits took longer to sprout compared to the other herbs, and the soil discs require careful rehydration to avoid oversaturation. Overall, this kit offers exceptional value for anyone wanting multiple culinary herbs plus catnip in a single purchase.
What works
- Includes complete tool set — no extra shopping
- High germination rate across multiple herb varieties
- Clear step-by-step instructions for beginners
What doesn’t
- Basil seeds may germinate slower than other varieties
- Soil discs need careful hydration to avoid soggy soil
2. PLANTMEW Cat Grass Kit
The PLANTMEW Cat Grass Kit focuses on fast, high-germination cat grass using non-GMO wheat grass seeds and coconut coir soil discs that expand quickly with water. The wooden planter has a clean, natural aesthetic that blends into home decor, and the entire setup sprouts visible growth within three to seven days according to multiple verified buyers. The three seed packets provide enough material for several growing cycles, making this a long-lasting solution for households with multiple cats.
Reviewers consistently report that their cats love the fresh grass and that it helps with digestion and hairball reduction. One apartment dweller noted the grass grows well under artificial light when direct sunlight is unavailable. The kit also includes mini gardening tools, though several owners mention the tools have poor build quality with metal tops detaching from handles easily.
Despite the tool quality issue, the core growing components perform reliably. The kit is mess-free and the hydroponic-style setup avoids soil spills. This is a solid entry-level pick that prioritizes quick results and pet health over decorative extras.
What works
- Fast sprouting — visible growth in 3–7 days
- Reusable wooden planter fits home decor
- Promotes healthy digestion and hairball control
What doesn’t

- Outdoor usage listed but best suited for indoor
3. The Cat Ladies Organic Cat Grass Growing Kit
The Cat Ladies kit takes an elevated approach with a white ceramic planter and a separate bamboo tray that catches drips, making it the best-looking option for style-conscious cat owners. The seed blend includes wheat grass, oat, barley, and rye—all organic and GMO-free—providing a diverse nutrient profile that supports feline digestion. The soil disc expands quickly, and the clear instructions guide users through the process with minimal guesswork.
Buyers consistently praise the fast growth (sprouts appear in 4–7 days) and the fact that cats enjoy nibbling the grass, which deters them from chewing on toxic houseplants. The ceramic planter has no drainage holes, which is a deliberate design to prevent water from leaking onto surfaces, but it also means users must be disciplined about not overwatering. One reviewer noted the planter is priced on the higher side considering the amount of soil and seeds provided.
Overall, this kit is ideal for anyone who wants a cat grass setup that doubles as a decorative piece. The organic seed mix and sturdy ceramic vessel justify the premium price, especially for buyers who plan to reuse the planter for multiple growing cycles.
What works
- Elegant ceramic planter with bamboo tray
- Fast 4–7 day sprouting time
- Organic, GMO-free multi-seed blend
What doesn’t
- No drainage holes — requires careful watering
- Higher price relative to seed & soil quantity
4. AVERGO Cat Grass Kit
The AVERGO Cat Grass Kit differentiates itself by providing four separate seed packets instead of the typical three, giving buyers more growing cycles before needing a refill. The natural wooden planter has a warm, earthy look that fits well in kitchens and living rooms, and the included coconut coir soil discs expand reliably without becoming compacted. The kit also supplies mini gardening tools and a pair of scissors for trimming the grass.
Customer reviews highlight the easy setup and fast sprouting—most saw growth within four to seven days. One reviewer noted the kit arrived well-packaged and included everything needed, and their cat was happily chewing on wheat grass after just over a week. However, a few owners reported that the included shovel had some rust spots, and one buyer was still waiting for growth after two days, though that may be within the normal germination window.
This kit is best for multi-cat households or owners who want to maintain a continuous supply of fresh grass without constantly reordering. The extra seed packet and sturdy wooden planter make it a worthwhile investment for long-term use.
What works
- Four seed packets for extended growing cycles
- Sturdy natural wooden planter
- Fast germination in 4–7 days
What doesn’t
- Small rust spots reported on metal tools
- Initial growth may occasionally lag slightly
5. Seedphony 25 Culinary Herb Seeds Variety Pack
Seedphony’s massive variety pack contains over 13,000 seeds across 25 herb varieties, including catnip, basil, rosemary, cilantro, dill, parsley, oregano, thyme, mint, lavender, and more. The seeds are non-GMO heirloom and come in individual sealed packets inside a waterproof resealable bag. A QR code on the packaging links to a comprehensive growing guide and bonus culinary e-book, which is a thoughtful touch for gardeners who want to explore cooking with their harvest.
Buyers generally report good germination rates and appreciate the sheer breadth of options. One reviewer successfully planted several varieties and noted that the seeds sprouted well, though some seeds may have washed away in outdoor conditions. The kit also includes a leaf clipper, seed dibber, tweezers, weeding fork, and widger tool—all functional if not premium. The 90%+ germination claim is backed by multiple positive experiences.
This kit is not a dedicated catnip grow setup—it’s a seed library that includes catnip among many other herbs. If your primary goal is just catnip, a more focused kit may be simpler. But for adventurous gardeners who want to grow an entire herb garden alongside their catnip, this is the most extensive option available.
What works
- Massive seed count — 25 varieties for total garden diversity
- 90%+ claimed germination rate on heirloom seeds
- Includes digital growing guide and recipe e-book
What doesn’t
- No dedicated planter or soil included
- Overwhelming variety for catnip-only buyers
Hardware & Specs Guide
Seed Germination Rate
High-germination catnip seeds maintain a viability rate above 90% when stored in a cool, dry environment. Sealed packaging is critical because moisture and temperature fluctuations degrade the embryo inside each seed. Kits that provide heirloom or non-GMO seeds from reputable suppliers consistently outperform generic bulk seed packets in real-world backyard and windowsill trials.
Soil Composition and Drainage
Catnip requires loose, well-draining soil to prevent root rot. Coconut coir or peat-based soil discs that expand with water offer the right balance of moisture retention and aeration. A planter with drainage holes is strongly recommended; without them, you must monitor water input carefully. A saucer or tray underneath catches excess water without soaking the pot’s base.
