Short version
What are the main benefits of cat grass?
Cat grass is young cereal grass, such as wheat, oat or barley, grown for cats to nibble. For indoor cats, its main benefits are that it helps with hairballs, gives them a safer plant to nibble than houseplants, and adds enrichment and routine to their day. Sprouties grows organic wheat, oat and barley grass and delivers it fresh in ready-to-nibble boxes across the UAE.
A safer plant to nibble
Indoor cats often look for greens to nibble. A box of cat grass gives them a safe, organic plant of their own, in place of houseplants that may not suit cats.
Enrichment and routine
Fresh grass gives indoor cats something to explore, nibble and return to: a small ritual in their day.
One angle per grass
Wheat as a daily ritual for cats prone to stress, oat for cats who are particular about what they eat, and barley for adult and senior cats.
What each grass contains
Wheat naturally contains chlorophyll, vitamins C and E, and trace minerals. Oat contains fiber and minerals. Barley, harvested young, contains natural antioxidants, vitamins C and E, and carotenoids.
When to call your vet
If your cat eats a lot at once and brings it back up often, offer the box in shorter sessions and check with your vet.

Cat grass benefits FAQ
Is cat grass good for your cat?
Yes. Cat grass helps with hairballs and adds enrichment to your cat's day, and it is a safe plant to nibble when it is grown from cat-friendly cereal grasses without pesticides. Offer it alongside a complete diet.
Are there any downsides to cat grass?
Some cats eat a lot at once and bring a little back up now and then. If yours does, offer the box in short sessions. Choose grass grown without pesticides or treated soil, and check with your vet if it happens often.
How often should cats eat cat grass?
Most cats can have regular access and nibble at their own pace. If your cat eats a lot at once, offer the box for 10 to 15 minutes at a time instead of leaving it out all day.
Is cat grass healthy for humans?
Sprouties boxes are grown for cats to enjoy. If you would like wheatgrass for yourself, choose a product made and labelled for human consumption.
