Care & safety

Let fresh grass stay a comfortable ritual.

Cat grass is enrichment, not a medical treatment. Introduce it thoughtfully, keep the crop fresh, and ask your veterinarian about individual health concerns.

Read the full growing guide
When is wheatgrass ready?

The current guide suggests offering grass around 3–5 inches tall. Growth usually takes 5–7 days, depending on conditions.

What if the first shoots look yellow?

Yellow shoots are normal just after blackout. They should turn green within a few hours in normal indirect daylight.

How do I know if a crop is not safe?

Fine white root hairs can be normal. Gray, green, blue or black growth—or a sour smell—means the batch should be discarded and the equipment cleaned.

Can I grow catnip in this tray?

No. The current guide says catnip should be grown in its own pot of well-draining soil and should not be soaked.

Questions before you grow?

For cats with allergies, digestive conditions, or unusual reactions, ask your veterinarian before introducing cat grass.

How long does it take to grow?

Wheatgrass, oat grass, and barley are typically ready in about 5–7 days under recommended conditions. Temperature, light, watering, and seed variety can affect growth time.

Do I need potting soil?

No soil is needed when growing wheatgrass, oat grass, or barley in the FelineBoost kit. The kit uses a hemp growing mat. Grow catnip separately in a small pot with soil.

How do I water it?

For the kit method, slowly pour 2½ cups of water over the hemp mat during setup so it is evenly moist and excess water collects below. Avoid waterlogging and follow the growing guide as the grass develops.

Is cat grass a medical treatment?

No. Cat grass is supplemental greenery and is not a medical treatment or a replacement for a complete diet. If your cat has a medical condition or unusual reaction, stop use and consult your veterinarian.

Can I reuse the planter?

Yes. Remove the used mat after each crop, then wash and fully dry the reusable planter and tray before starting again with a fresh hemp mat and seeds.
