At Home with an Indoor Cat

Why so many indoor cats get a box of grass of their own, what the research says, and how to look after the box at home.

At Home with an Indoor Cat - Sprouties
Quick answer

An indoor cat rarely gets the chance to nibble grass on their own, and many houseplants are not safe for cats. A box of fresh cat grass gives them a green grown to be nibbled. Offer it in a calm spot, out of direct sun, and let your cat decide.

Meet the indoor cat: expert napper, window supervisor, connoisseur of the one sunny patch on the floor. Across the UAE, plenty of cats live their whole lives indoors, in homes kept closed and cool for much of the year. We went behind the scenes of that indoor life to answer one question: why do so many indoor cats get a box of grass of their own, and what does the research actually say?

Q: Want to start with the basics?

A: Gladly. Cat grass is the young grass of cereal plants, wheat, oat and barley, grown for cats to nibble. Ours is organic, grown hydroponically in the UAE, and delivered fresh.

Q: Do cats really eat plants, or is that just something people say about them?

A: They really do. In a 2021 paper, Hart and colleagues reported owner surveys in which 725 of 1,021 cats had been seen eating plants at least six times, and only 112 had never been seen doing it. The sample was selected, so it is not a global head count, but that is a lot of nibbling.

Q: So what is different about an indoor cat?

A: Opportunity. A cat with a garden can find grass on their own. An indoor cat usually cannot, and the plants that are indoors tend to be decorative houseplants, many of which are not safe for cats. A box gives them a green that is grown to be nibbled.

Q: Is anyone actually recommending grass for indoor cats, or is that just us?

A: Not just us. The Australian Capital Territory's 2007 welfare code for cats recommends grass twice weekly when owners lack garden access. A 2010 clinical review of indoor cats by Herron and Buffington suggested suitable grasses as a chewing outlet, and a 1999 housing review by Rochlitz suggested considering grass for cats that like chewing. None of these is a medical trial, and none says grass treats anything. They are practical advice from people who think hard about how cats live, and they point the same way: give an indoor cat the chance to nibble something green.

Q: How many homes actually offer their cat grass?

A: Fewer than you might think. A 2025 paper by Taylor and colleagues reported a 2021 social-media survey of 565 UK cat caregivers, and 84 of them, 14.9%, provided cat grass. It is one survey in one country, and it says nothing about how much the cats ate, but it suggests grass is still the exception rather than the rule.

Q: Room to grow, then.

A: Exactly. (We had to.)

Q: Our cat has never had grass in her life. Will she even be interested?

A: Maybe, maybe not, and both answers are fine. Every cat is different. Some cats sniff, chew and come back on day one. Others ignore the box for a while before deciding it was their idea. The UK charity Cats Protection advises offering suitable grass and accepting it if your cat says no, and that is our advice too. Put it down, step back, and let her choose. If she eats a lot at once and brings it back up often, offer the box for 10 to 15 minutes at a time instead.

Q: What does a box actually add to an indoor day?

A: Something to explore, mostly. Fresh grass to sniff and nibble brings a little variety to an indoor routine, it gives your cat a safer green than a decorative houseplant, and all three of our grasses help with hairballs. It is a choice your cat can make for themselves, whenever they like.

Q: Where should the box go in a small apartment?

A: Somewhere calm that your cat already likes, near where they rest or sit, and easy for them to reach. Keep the box out of direct sun. In the UAE summer, the fridge works well. If you have more than one cat, make sure each of them can get to it.

Q: And watering? We are not exactly plant people.

A: You don't need to be. Two days after the box arrives, add a little water at the base of the box, never on the grass. That's it. No misting, no sunlight schedule, no growing. When the grass yellows or wilts later in the week, it has reached the end of its time and can go in the compost.

Q: How long does one box last an indoor cat?

A: A box stays good for about 7 days from harvest. In a home with several cats, a box is usually finished in two to three days. A weekly plan brings a fresh box every week; every 10 days or every 2 weeks suits cats who nibble less, and Build Your Plan offers up to 4 boxes per delivery for busy multi-cat homes.

Q: How does it actually get to us?

A: Order today and your box arrives the next day. We harvest it the morning it is delivered, pack it chilled, and it reaches you the same day between 12 PM and 10 PM, across all seven emirates. There are no deliveries on Sundays or UAE public holidays, so a Saturday order arrives on Monday. If the courier cannot reach you, they call or send a WhatsApp, and grass is never left unattended. Delivery is free on every plan and on one-time orders of 2 or more boxes.

Q: So is it worth trying?

A: Ask your cat.

Q: What if my cat has a health condition, or is on a special diet from the vet?

A: Then talk to your vet before adding anything new, grass included. That goes double for cats with recurrent vomiting, constipation, trouble swallowing, a sore mouth, allergies or a medically managed diet. Grass is a small, pleasant extra in an indoor day, never a substitute for veterinary care, and it is not a treatment for anything. If your cat brings grass back up now and then, that is nothing unusual: most cats nibble grass, and most are healthy when they do. If it happens often, or your cat seems unwell, your vet is the person to see.

Q: Any last tips for indoor cat homes?

A: Keep any houseplants that are not safe for cats out of reach, grass or no grass. Offer the box, watch, and let your cat decide how much they want. And enjoy the view. There are few things more peaceful than an indoor cat discovering something green.

Not sure which grass to start with? Wheat is our most popular grass, soft and fine, a daily ritual for cats prone to stress. Oat is crisp, for cats who are particular about what they eat. Barley has broad leaves, for adult and senior cats who nibble at their own pace. Or let your indoor cat try all three.
