Despite cats being obligate carnivores, they still like to nibble on a little grass. Experts are divided on why cats do this; it could be to get some trace vitamins and minerals in their diets or it may just be a behavioral instinct leftover from back when cats’ diets consisted entirely of live prey. Whatever the reason, growing your own cat grass is a great way of providing your feline friend with some safe, conveniently-located greenery to munch on.
We reviewed dozens of cat grass products to find the best out there. We considered a range of factors, such as seeds versus growing kits, whether you receive a planter, whether the seeds are organic and/or GMO-free, and the opinions of people who’ve bought and used these products.
Our favorite cat grass product is the Handy Pantry Reclaimed Barnwood Style Planter Wheatgrass Kit. It features a generously-sized reclaimed wood planters, organic wheatgrass seeds, and soil pucks. There’s enough of everything for three plantings.

Best Cat Grass Overall: Handy Pantry Reclaimed Barnwood Style Planter Wheatgrass Kit
Cat grass might be beneficial to your cat but it doesn’t always look good in your home. With the Handy Pantry Reclaimed Barnwood Style Planter Wheatgrass Kit, however, you get the best of both worlds. Not only does it include everything you need to grow cat grass, it also includes an attractive reclaimed wood planter that’s as stylish as it is practical. Now your feline friend’s cat grass is a fun design feature, as well as an enjoyable snack.
Whereas some other cat grasses include a mixture of grass species, the included seeds are for hard red wheat only. Wheatgrass is a great form of cat grass, but some buyers may be disappointed by the lack of diversity. You can, of course, mix in other cat grass seeds if you choose but unless you have a reason to require a range of cat grass species, wheatgrass should do just fine. In addition to the seeds and planter, you get three soil pucks. Once rehydrated, each one provides enough soil to fill the planter.
At $33, it’s a little pricier than most cat grass, but considering the size and quality of the planter, we think it offers great value for money.
Handy Pantry Reclaimed Barnwood Style Planter Wheatgrass Kit Key Features:
- Included wheatgrass seeds are certified USDA organic
- Kit contains enough soil and seeds for three plantings, so you can regrow once your cat eats it all or the blades get too thick
- Planter is handmade in the USA

Important Features to Consider
Cat grass should have a few important features. Here’s what to consider when selecting cat grass for your feline friend:
- Growing kits vs. seeds. You generally need to grow your own cat grass as its short life cycle makes it hard to buy already grown. You can either buy a growing kit (which contains seeds, soil, and sometimes a growing container) or just seeds. Seeds often offer better value, especially if you already have potting soil and pots, but growing kits are easier.
- Planter. Some cat grass kits also come with decorative planters, usually made of ceramic or wood. These are different from the plastic trays or grow bags that are included in cheaper kits.
- Organic. It’s preferable to choose organic cat grass seeds since your cat will be eating the grass. Ideally, look out for certified USDA organic seeds, but some are pesticide-free without certification, since it costs money to get certified.
- GMO-free. Cat grass that’s GMO-free doesn’t contain and genetically modified organisms. While there isn’t anything inherently wrong with GMOs, they’re often exploited by large corporations (such as Monsanto patenting seeds) so some people prefer to avoid GMOs on ethical grounds.
- Plant species. Cat grass isn’t one particular plant, it’s a generic name given too the young sprouts of a range of plant species, including wheat, oats, and rye. Some cats have a preference for one variety of cat grass over others, but most cats aren’t bothered which plant species is used.
Frequently Asked Questions
What is cat grass and what are the benefits for cats?
Cat grass is simply the young shoots of grass-like plants. Cat grass can be a mix of several grass species or may simply be a single species (100% wheatgrass is an extremely common type of cat grass). One of the main benefits is that it’s a source of micro-nutrients for cats, and may contain some vitamins and minerals lacking in a carnivorous diet. It’s also a good source of insoluble fiber, which can aid in hair ball reduction. An added bonus is that cats just seem to enjoy nibbling on it, so it adds some environmental enrichment.
What kind of grass is good for cats?
If it’s labelled as cat grass, it’s probably good for your cat, or at least feline-safe. Common types of cat grass include wheatgrass, oat, alfalfa, rye, flax, and barley.
Do indoor cats need cat grass?
Yes, indoor cats have more need for cat grass than cats who have access to the outside world, since indoor cats won’t have any other grass available to them and may resort to munching on house plants. Of course, outdoor kitties can still enjoy cat grass in the home.
How often should I water cat grass?
After the initial watering and it starts to sprout, lightly spray your cat grass with a plant mister daily. Don’t over-water it as it can lead to mold in the roots, which will kill the plants.
