A Norwegian Forest Cat is not a small animal with a polite nibbling habit. Wegies commonly weigh 5–8 kg, with big males pushing past 9 kg, and they approach a pot of fresh grass the way they approach everything: with their whole body. A lightweight plastic tray that would survive a dainty 3 kg cat gets shouldered off the windowsill, dug in, or simply sat on by a Forest Cat mid-graze. If you’ve already swept up one soil explosion, you know exactly why you’re searching for the best cat grass kits for Norwegian Forest Cats specifically.
Cat grass itself — usually wheat, oat, barley or rye grass grown from seed — is a genuinely useful thing to offer an indoor cat. The fibre supports normal digestion and helps loose hair move through the gut rather than coming back up quite so often, and grazing gives a big, intelligent, semi-wild breed something natural to do. Just as importantly, a pot of their own grass is the best distraction you can offer a cat who has otherwise discovered your houseplants — and that matters, because many common houseplants are toxic to cats, and lilies in particular are lethal even in tiny amounts. Cat grass is enrichment and a safe grazing outlet. It is not a hairball cure, and it never replaces keeping dangerous plants completely out of reach.
We compared the leading Amazon grow kits on the things that actually decide success with a large breed: planter weight and stability, seed quality and blend, how much you get in the box, and how easy it is to keep a fresh rotation going. Here are the five that earned a place.

What to Look for in a Cat Grass Kit for a Norwegian Forest Cat
- Planter weight and stability — the big one: For most cats this is a nicety; for a Wegie it’s the whole ballgame. Ceramic and solid wood planters with a wide base stay put when a 7 kg cat leans in and tugs at the blades. Feather-light plastic trays get dragged, tipped and dug out. If you do choose a light kit, stand it inside a heavy ceramic tray or on a non-slip mat.
- A proper seed blend: Blends of wheat, oat, barley and rye germinate reliably and give a mix of blade textures. Check the seed is sold for pet grazing and is untreated — never sow lawn seed or garden seed mixes, which may be coated with chemicals or fertiliser.
- Enough seed for a rotation: A big cat flattens a small pot in days. Grass stays at its best for roughly one to two weeks, so kits with multiple seed packs — or cheap refills — let you sow a fresh pot every week and always have one ready.
- Soil discs vs. loose soil: Compressed coir or soil discs are tidy, expand with water, and store well between sowings. They also make it easy to start a pot in a cupboard (grass germinates happily in the dark) and move it to the light once it sprouts.
- Mould resistance starts with you: The biggest cause of failed, mouldy pots is overwatering. Look for planters with drainage or a tray, water little and often, and give the pot air flow — more on this in the safety notes.
1. The Cat Ladies Two Ceramic Planters Kit — Best Overall
This is the kit we’d hand a Norwegian Forest Cat owner first, because it solves the stability problem properly. You get two white ceramic planters (about 3.9 × 3.9 × 4 in each) sitting on bamboo trays, two soil disks and the brand’s organic seed blend of wheat, oat, barley and rye. Ceramic has real heft — the packaged kit weighs around 1.6 lb — and once filled with damp soil, each planter is a solid, low unit that a big cat can graze from without skating it across the floor.
The two-planter format is quietly perfect for this breed: sow both a few days apart and you can rotate them, resting one while your Wegie demolishes the other. The brand says to expect sprouts up to 4 inches within about 4–7 days, and the seeds are organic and GMO-free, grown in the USA. At the time of our research this listing held a 4.4-star average across more than 200 ratings.
Pros: Genuinely heavy ceramic planters with trays; two pots enable rotation; organic four-grain seed blend; looks like home décor, not pet clutter.
Cons: Ceramic can chip or crack if dropped on hard floors; modest grazing area per pot for a very large cat — sow both.
Best for: Most Norwegian Forest Cat homes — the stable, attractive, no-fuss starting point.
2. Rootcraft 5-Pack Cat Grass Kit with Wood Planter — Best Complete Kit
If you want everything in one box and plenty of seed in reserve, Rootcraft’s kit is the generous option. The 16-piece set includes a wooden planter box with a plastic liner, five packets of organic non-GMO wheatgrass seed, three soil discs, plant food, a spray bottle, scissors, tweezers and mini gardening tools. Five seed packs is months of grazing for one cat, and the wooden box format gives a longer, lower grazing trough that suits a big cat better than a round pot.
The growing routine is the standard, reliable one: expand the discs, sow a packet or two, mist daily with the included spray bottle, and expect sprouts in 1–3 days with grass ready at 4–5 inches in about 4–7 days. The brand quotes a 95% germination rate for its seed and backs the kit with a 180-day satisfaction guarantee. Honest caveat: the wooden planter is usefully weighty once filled, but it’s lighter than ceramic — put it on a mat, not a polished sill edge.
Pros: Five seed packs — the best supply in this roundup; trough shape suits large cats; tools, spray bottle and scissors included; guarantee.
Cons: More pieces than minimalists need; wood planter needs its liner used properly to protect it from moisture.
Best for: Owners who want one purchase to cover a whole season of grass.
3. AVERGO Cat Grass Kit with Wooden Planter — Best Compact Wooden Planter
AVERGO’s kit keeps things simple: a compact wooden planter, two packets of cat grass seed and coconut coir soil discs. Just add water, sow, and sprouts appear within days. It’s a tidy, natural-looking little trough that fits a kitchen counter or a wide windowsill, and the low wooden box is a steadier shape than the tall, narrow pots that big cats tip over.
Two seed packets is a sensible starter supply rather than a stockpile, and the same planter can be re-sown with any pet-grass seed refill afterwards. AVERGO is a US company and positions this as its mid-size option, between a smaller mini kit and a larger multi-packet set — so if your Wegie turns out to be a champion grazer, the format scales up.
Pros: Simple, good-looking wooden trough; coir discs are clean and easy; low profile resists tipping; compatible with any refill seed.
Cons: Only two seed packets included; smaller grazing area than the Rootcraft trough.
Best for: First-time growers and smaller spaces who still want a planter with some substance.
4. The Cat Ladies Black Cat Planter Mug Kit — Best Single Sturdy Planter
Sometimes you want one good planter, not a system. This kit pairs a black ceramic cat-shaped mug planter (about 4.6 × 5.5 × 6.1 in) with a soil disk and The Cat Ladies’ organic, locally sourced seed mix — the same wheat, oat, rye and barley blend as our top pick. At around 12.3 oz before soil, the ceramic mug has enough heft to sit still under an enthusiastic grazer, and its taller shape keeps the soil contained when paws investigate.
The method is the brand’s usual three steps: drop in the disk, add water, sprinkle seed and keep the soil moist in a semi-dark spot until sprouts appear, then move to the light. Expected grass height is up to about 8 inches on this listing if you let it grow on, though most cats prefer it younger and more tender. It also makes a genuinely charming gift for a Forest Cat owner — which is not something we’d say about most litter-adjacent purchases.
Pros: Solid ceramic weight; organic seed blend; deep mug contains digging better than shallow trays; giftable.
Cons: Single pot means no rotation unless you buy refills and a second container; the cute shape has a smaller opening than a trough.
Best for: Single-cat homes and anyone who wants one handsome, heavy planter on the sill.
5. The Cat Ladies Cat Grass Grow Kit, 3 Pack — Best for a Fresh Rotation
The smart way to keep grass in front of a big grazer is staggered sowing — one pot in use, one growing, one resting — and this 3-pack is built for exactly that. You get three BPA-free growing trays, three soil disks and three packets of organic, non-GMO seed (locally sourced in the USA). It’s a popular format: at the time of our research it sat at #1 in Amazon’s Grass Seed category.
Now the honest part, because it matters for this breed: these trays are lightweight plastic, and a determined 8 kg Wegie can absolutely move one. The fix is simple — stand each tray inside a heavy ceramic saucer or a weighted wooden box (the AVERGO or Rootcraft planter works), or site the in-use pot on the floor in a corner where tipping does no harm. With that one adjustment, this is the most economical way to guarantee fresh grass every single week.
Pros: Three of everything for true rotation growing; organic seed; low cost per sowing; trays are easy to wash between crops.
Cons: Trays are light — must be weighted or contained for a large, strong cat; less attractive than ceramic or wood.
Best for: Heavy grazers and multi-cat homes that get through grass fast.
Ceramic vs. Wood vs. Trays: Which Should You Choose?
Ceramic (The Cat Ladies ceramic kits) wins on pure stability and looks, and wipes clean in seconds. Wooden planters (Rootcraft, AVERGO) offer a longer trough shape that’s kind to whiskers and big muzzles, with moderate weight — use the liner and they’ll last. Plastic trays (the 3-pack) are the rotation workhorses: cheapest per crop and easiest to stagger, but they need a heavy base or a sensible spot with a Forest Cat in the house. Many Wegie owners end up with a hybrid: a handsome ceramic or wood planter for daily grazing, plus one tray quietly growing on a shelf.
Safety Notes Before You Sow
- Lilies are lethal to cats. True lilies (including Easter, tiger, day and Asiatic lilies) can cause fatal kidney failure from even a small nibble or pollen groomed off fur. Keep lilies — plants and cut flowers — out of your home or entirely out of reach; cat grass is a distraction, not a safety device. Other common houseplants such as pothos, philodendron, dieffenbachia and sago palm are also toxic; check the ASPCA plant list before bringing any plant home.
- Only grow seed sold for pets. Never sow lawn seed, wild bird mixes or leftover garden seed — they may be treated with fungicides or fertilisers. Stick to kit seed or plain untreated wheat/oat grain.
- Don’t overwater. Soggy soil grows mould, and mouldy grass should be binned, not served. Keep soil damp, not wet; mist rather than soak; ensure drainage and air flow; and replace the whole crop when it yellows or smells sour — for most pots that’s every 1–2 weeks.
- Grass is not a hairball cure. Occasional hairballs are normal for a long-coated breed, but frequent vomiting, unproductive retching, appetite loss or lethargy are vet problems, not grass problems. See your vet promptly if you spot them.
- Mind the digging. Some Forest Cats excavate. A heavier planter, a layer of larger-grain soil on top, and siting the pot away from soft furnishings will save your floors.
Frequently Asked Questions
How much cat grass will a Norwegian Forest Cat actually eat?
More than you’d expect from a smaller breed — a big Wegie can flatten a small pot in a few days of enthusiastic grazing. That’s why we favour kits with several seed packs and a rotation system: sow weekly and there’s always a fresh pot coming on.
How long does cat grass take to grow, and how long does it last?
Most of these kits sprout within 1–3 days and reach grazing height (around 4 inches) in roughly 4–7 days. A crop is at its best for about one to two weeks before it yellows and gets tough; then compost it and sow again.
Can I just grow wheatgrass from health-food seeds instead?
Plain, untreated wheat, oat, barley or rye grain is essentially what these kits contain, and growing your own in a heavy planter you already own is a perfectly good option. The kits earn their keep with convenience — measured seed, soil discs, and a planter chosen for the job. What you must avoid is any seed treated or coated for lawns or gardens.
My cat eats the grass and then vomits. Is that normal?
Occasionally, yes — cats sometimes vomit after grazing, and a hairball coming up with it is common in long-coated breeds. But regular vomiting is not something to accept or to treat with more grass. If it’s happening often, or your cat is off their food, losing weight or retching without producing anything, that’s a vet visit.
Will cat grass really keep my cat away from my houseplants?
It helps a lot — most cats prefer fresh grass to leaves when it’s offered — but it’s not a guarantee. Treat grass as one layer of the plan: put genuinely toxic plants (lilies above all) somewhere your cat cannot reach at all, or don’t keep them.
Our Verdict
For most Norwegian Forest Cat homes, start with The Cat Ladies Two Ceramic Planters Kit — heavy planters that stay where you put them, a good organic seed blend, and a built-in rotation. Choose the Rootcraft 5-Pack if you want the biggest seed supply and a trough format, AVERGO for a compact wooden planter, the Black Cat Planter Mug for a single sturdy pot, and the 3-Pack Grow Kit if your cat grazes hard and you want a constant conveyor belt of fresh grass. Whichever you pick, weigh it down, water it lightly, and keep the lilies out of the house.
