The best cat grass plants, compared.
Top pick: Webbox wheatgrass kit Best value: Webbox wheatgrass kit – Best value on a different ASIN: score 88, a 120 g wheatgrass kit at about £6.10 with 4.3 from 1,768 reviews, if you can wait and sow again. Updated 21.10.2026.
A cat grass plant on amazon.co.uk is not one species. You are usually buying for an indoor cat, or for a cat that already chews houseplants, and you want a green that is safer than a sprayed lawn. The shelf splits three ways: a ready pot of young wheat, barley, oats and sometimes rye; a wheatgrass seed kit you sow yourself; or ', a sedge sold as a longer-lived nibbling plant. And treat grass eating as normal and the hairball story as a theory. They tell you to avoid pesticides and lilies. Two pairs of listings share one review pool, so those counts are not added. A different houseplant shelf is the [snake plant comparison](/hub/houseplants/snake-plant). A cat grass plant is the green you put out for a cat that eats grass, usually indoors, so the animal is not chewing a sprayed lawn or a lily. A treat stick, a faux plant, or an empty planter is a different purchase. How those types differ, and the trap of two listings sharing one review pool, is set out in the [cat grass buying guide](/hub/houseplants/cat-grass-plant/sub/cat-grass-plant-buying-guide).

Question 1 of 2
When do you need leaves?
The Webbox PT864443 is a 120 g wheatgrass seed kit at £6.10 on this amazon.co.uk snapshot, with 4.3 from 1,768 reviews, and the box is seeds in a carton rather than a living pot. Reviewers often report shoots within a few days, and some say the tray is ready to nibble around five or six days. Indoor cats in those reviews frequently eat the result, and several people describe the growing medium as cleaner than garden soil. A recurring complaint is that a tray dies quickly, while other cats sniff the grass and walk away. Mixing seed and medium is called fiddly and messy. The listing's line about eliminating hairballs is a seller claim, not a result counted in the reviews. In this set it is the best value pick when you can wait and sow again, and the wrong parcel if the cat needs leaves this evening.
Pros
Cons
Best for: You can wait several days and want a cheap wheatgrass kit you can sow again.
Less suitable: You need a nibble this evening, or your cat has already refused a wheatgrass tray.
Specifications
Common questions
Does this arrive as a living plant?
No. The item form is Seeds and the package size name is Kit. The listing does not describe a pot of grown grass.
What do the reviews repeat?
Reviewers often say it grows within days and that indoor cats eat it. Others say a tray died quickly, the cat refused it, or setup was fiddly and messy.
Are the four growing steps printed on the listing?
The special-features line says an easy kit with four simple steps. The steps themselves are not printed in the details we kept.
Cat Mommy's one-pot mix is a ready 12 cm pot of wheat, barley, rye and oats at £10.99, with the country-of-origin field set to United Kingdom and 4.2 from 80 reviews that are not the three-pot sample. Reviewers describe fresh grass eaten while the box is unpacked, including indoor cats that had been chewing other houseplants, and at least one notes a small seaweed compost sachet. The same listing records pots that arrived mostly yellow, a short indoor life, and cats that ignore the grass. One reviewer says the fertiliser sachet did not bring a tired pot back. There is no pesticide certificate beside the unanswered FAQ. In this comparison it is the top pick when you want a ready cereal pot with its own, smaller review sample rather than a seed kit.
Pros
Cons
Best for: You want one ready cereal pot today and will reorder when the blades fade.
Less suitable: You need grass for the whole season, or you will only buy on a four-figure review count.
Specifications
Common questions
How many pots are in this listing?
The unit count is 1. The item form says 1 × 12 cm pot. The title ends in One, Mix.
Does the listing say where it is grown?
The country-of-origin field says United Kingdom. A pesticide question is on the page with no certificate.
What do the reviews repeat?
Fresh grass that cats nibble, and also yellow or tired pots, a short indoor life, and cats that ignore it. One review mentions a seaweed compost sachet.
Cat Mommy's multi-pot listing is £15.99, with a United Kingdom origin field and 4.0 from 175 reviews of its own. The title names oats, barley and wheat, while another line and the ingredients line also add rye, and the unit count says 3 while the number-of-items field says 4. Reviewers often praise fresh green pots that indoor cats sniff and eat, and some call three pots good value. Others say the grass dries within days even when watered, soil escapes the pots, and fruit flies appear, including one pot dead within 48 hours. Heat damage after the courier, and pots that look like the same grass despite grain labels, come up again. The weight field is 700 g, the same figure as the single pot, which is a thin mass for three pots of compost.
Pros
Cons
Best for: You want several ready pots in one order and will count them on the doorstep.
Less suitable: You need one agreed pot count on the listing, or a single pot at £10.99.
Specifications
Common questions
How many pots does the listing claim?
The title and unit count say three pots of 12 cm. The number-of-items field says 4. Both figures are on the listing.
Which grasses are named?
The title says oats, barley and wheat. Another line and the special-ingredients line add rye. One review said the pots looked the same.
What do the reviews repeat?
Fresh green pots that cats eat, and also drying within days, spilled soil, fruit flies, and heat damage in the post.
Carbeth's one-pot listing is a live Cyperus 'Zumula' in a 13 cm pot at £11.49, with an expected-height field of 30 cm and 3.9 from 1,116 reviews shared with the two-pot ASIN. Reviewers often call it greener and larger than a seed-grown tray, well watered when the box arrives the right way up, and something cats nibble on the day it lands. One buyer said the plants thrived from April once they were kept off bright sun. The same shared texts complain about plants smaller than the photo, yellow leaves after a dark journey, soil spilled from an upside-down box, and cats that still ignore it. The care line asks for bright indirect light and soil that is not allowed to dry out. It is umbrella sedge, not wheatgrass, and a retailer magazine warns those blades can be sharp.
Pros
Cons
Best for: You want one longer-lived sedge and will keep the compost moist out of direct sun.
Less suitable: You want soft wheatgrass this evening, or a review sample that is not shared.
Specifications
Common questions
Is this wheatgrass?
No. The title and the listing name Cyperus 'Zumula' in a 13 cm pot. It is not the cereal mix.
What light and water does this listing state?
Sunlight exposure is partial shade. The care line says bright indirect light and soil kept moist, not dried out. Trim older shoots.
Are the 1,116 reviews only for one pot?
No. The same image, rank and review text are on the two-pot listing B09SNZRKHG.
The title on this Carbeth listing asks for two Cyperus 'Zumula' plants in 13 cm pots at £17.99, and the expected-height field on this listing is 13 cm, not the 30 cm printed on the one-pot ASIN. The star line is 3.9 from 1,116 and the review text matches the single plant, so a second pot does not buy a second thousand reviews. Shared comments still describe green plants that cats chew when the packing holds, and also yellow leaves, spilled soil and upside-down boxes. This listing does not repeat the longer care paragraph; it only says bright, indirect light and simple watering. Outdoor growing and safety for kittens are questions on the page with no answer. Pay £17.99 when you want two plants, not when you want a larger evidence base.
Pros
Cons
Best for: You want two Zumula plants and will keep both composts moist.
Less suitable: You wanted a second set of reviews, or the 30 cm height line from the one-pot listing.
Specifications
Common questions
How many plants does the title state?
Two Cat Grass 'Zumula' in 13 cm pots. Number of items is 2. The price in the snapshot is £17.99.
What height does this listing give?
The expected-height field says 13 centimetres. The one-pot ASIN's listing says 30 cm. This listing does not repeat that 30 cm line or the longer care paragraph.
Are these extra reviews on top of the single pot?
No. Stars, count, image, rank and review text match B08NT4HHRM.
This generic listing is one ready pot of wheat, barley, rye and oats at £9.99 and 650 g, with a 12 cm pot in the description and a package size name of Single Pot. The star line is 3.9 from 392 reviews, and those texts are the same pool as the four-pot ASIN, so they are not a separate sample of this size. Reviewers who like the delivery describe thick, fresh grass, a leaflet, and cats that nibble straight away, including at least one rabbit. Others say the photo looks like more than one pot, and some arrivals look sorry and do not recover. Royal Mail damage appears even with fragile labels, and a repurchase in the shared text mentions old grass or mites. The listing's 'up to two weeks' and the sunny-spot line are seller sentences, not a timed trial.
Pros
Cons
Best for: You want one live cereal pot today and will treat the stars as a shared sample.
Less suitable: You need reviews that belong only to the single pot, or a plant that lasts the season.
Specifications
Common questions
Is this the four-pot pack?
No. This listing's package size name is Single Pot, unit count 1, at £9.99 and 650 g. The description also mentions 1, 4, or 8 pots as a range.
Are the 392 reviews only for this pot?
No. The same star line, image and review text are on B0DGQJHJM2. Do not add the two counts.
How long does the listing say it lasts?
The listing says up to two weeks with proper care. That is a seller sentence, not a trial result.
This generic listing is the four-count line at £15.99 and 2 kg, still wheat, barley, rye and oats, with Variety Pack as the size name rather than four different plants. The 3.9 from 392 reviews are the same texts as the £9.99 single pot, including a complaint that the photo showed one pot, so they are not a trial of a four-pot delivery. Shared praise is lush grass, a leaflet, and cats that nibble when the parcel is intact. Shared complaints are sorry pots, courier damage, and mites on a repurchase. The listing's 'up to two weeks' is a seller claim, and the sunny-spot line is the same seller sentence as on the single pot. At £15.99 against £9.99 for one, the extra units only help if four pots are actually in the box.
Pros
Cons
Best for: You have checked that this ASIN ships four pots and you accept the shared stars.
Less suitable: You are paying for extra reviews, or you only need the single pot at £9.99.
Specifications
Common questions
How is this different from the £9.99 listing?
This listing's unit count is 4, weight 2 kg, price £15.99. The other listing is one pot, 650 g, £9.99. Image, model number, rank and reviews match.
Does Variety Pack mean different grasses?
The size name is Variety Pack. The ingredients line is still wheat, barley, rye and oats, the same mix as the single pot.
Do the reviews describe a four-pot delivery?
The reviews are the same text as the single-pot listing, including a complaint that the photo showed one pot. They are not a separate four-pot sample.
Scores use the seven amazon.co.uk listings kept in this comparison, the prices and star lines on those pages, and the review notes for the same ASINs. Shelf figures are the snapshot in the comparison files. This is not a laboratory test. A star rating is not a welfare trial. The notes add stars, review volume, listing fit and price. Weights below are those four parts scaled so they sum to 100. Awards follow the job, not the highest raw total. The Webbox kit scores 88 and is best value. The top pick is Cat Mommy's one ready pot, score 76, a living cereal pot with its own review sample. Carbeth's one-pot score of 78 stays unbadged because that plant is sedge, not the soft cereal this top-pick job is scoring.
Amazon stars
40%Stars are scaled from the amazon.co.uk rating out of 5, about (rating / 5) × 40. In this set 4.3 and 4.2 land on 34, 4.0 on 32, and 3.9 on 31. Seller lines about hairballs or immunity are not added.
Review sample
25%Volume is banded from the listing count: 1,768 reviews score 25, 1,116 score 24, 392 score 21, 175 score 18, and 80 score 15. Shared pools are not added. Carbeth's two ASINs are one sample of 1,116. The generic one-pot and four-count lines are one sample of 392.
Listing fit
20%A ready pot with its own reviews scores higher than a shared pool or a pack-count conflict. Cat Mommy's one pot is an own ready pot. The Webbox carton is a complete kit rather than a plant in the box. The three-pot listing loses fit because the unit count says 3 and the items field says 4. The two-pot Zumula listing also loses fit because its height field says 13 cm while the one-pot listing says 30 cm.
Price in this set
15%Value uses the snapshot price in this set only. £6.10 scores 15. About £10 to £11.49 scores 11 or 12. £15.99 scores 8. £17.99 scores 7. The kit is the highest price score, on a different ASIN from the top pick.
Choose the plant type before the price. A ready cereal pot, a wheatgrass seed kit and Cyperus 'Zumula' are not the same purchase, and two listings can share one review pool.
A cat grass plant is the green you put out for a cat that eats grass, usually indoors, so the animal is not chewing a sprayed lawn or a lily. On amazon.co.uk it is not one product. You are choosing a ready pot of young wheat, barley, oats and sometimes rye, a wheatgrass seed kit, or Cyperus 'Zumula', which is umbrella sedge sold as a longer-lived nibbling houseplant. A treat stick, a faux plant, or an empty planter is a different purchase.
Cyperus 'Zumula' is umbrella sedge. Wheatgrass and the cereal mix are the soft snack grasses. Zooplus Magazine warns the sedge blades can be sharp.
Carbeth's one-pot and two-pot pages are one sample of 1,116. The generic one-pot and four-count pages are one sample of 392. A second ASIN does not buy a second set of reviews.
Listings talk about up to two weeks. Reviewers describe drying, heat in the van and fruit flies. Reorder a cereal pot, or keep Zumula moist out of direct sun if you want a longer green.
A ready cereal pot is for a nibble today. Cat Mommy's one 12 cm pot is about £10.99 with its own 4.2 from 80. The generic single pot is about £9.99, on a shared sample. A seed kit is for a wait of several days and another sowing: the Webbox carton is 120 g of wheatgrass at about £6.10. Cyperus 'Zumula' is umbrella sedge, not wheatgrass. Carbeth's one 13 cm pot is about £11.49, with a 30 cm height field, and it wants bright indirect light and compost that does not dry out.
Match the pot count to the title before you pay. Cat Mommy's multi-pot listing is about £15.99: the title and unit count say three, and the number-of-items field says 4. The title names oats, barley and wheat, while another line adds rye. The generic four-count line is about £15.99 and 2 kg, and Variety Pack is still wheat, barley, rye and oats. Carbeth one-pot B08NT4HHRM and two-pot B09SNZRKHG both show 3.9 from 1,116.
Three typical situations, each with a recommendation from this comparison.
You want a nibble this evening and you will reorder when the blades fade. Cat Mommy's one 12 cm pot is the top pick: wheat, barley, rye and oats, a United Kingdom origin field, and 4.2 from 80 reviews of its own. Yellow pots and a short indoor life still show up in that sample.
Your cat chews houseplants and you want something that can still be green after a cereal tray has yellowed. Carbeth's one Cyperus 'Zumula' is the sedge in a 13 cm pot, with an expected-height field of 30 cm. Keep the compost moist and out of harsh sun. The blades can be sharp.
You can wait several days and you will sow again. The Webbox 120 g wheatgrass kit is best value at about £6.10, with 4.3 from 1,768 reviews. It is seeds in a carton, not leaves tonight, and some cats refuse the finished grass.
The top pick is Cat Mommy's one 12 cm pot at about £10.99. It scores 76 as a ready mix of wheat, barley, rye and oats, with a United Kingdom origin field and 4.2 from 80 reviews of its own. Reviewers describe fresh grass eaten on arrival, and also yellow pots, a short indoor life and cats that ignore it. Best value is a different listing: the Webbox 120 g wheatgrass kit at about £6.10, which scores 88, the highest total here, because the price is low and the review sample is large. It is seeds, not a living pot. Skip the Cat Mommy pot if you need grass for the season. Skip the Webbox kit if the cat needs leaves this evening. Carbeth's one Zumula pot scores 78 and stays unbadged because it is sedge, not the soft cereal this top-pick job is scoring.
Webbox wheatgrass kit
Best value on a different ASIN: score 88, a 120 g wheatgrass kit at about £6.10 with 4.3 from 1,768 reviews, if you can wait and sow again.
