How to Grow Your FelineBoost Cat Grass Sampler

Discover which fresh grass your cat loves most.

Your sampler includes different seed varieties, but they do not all grow the same way:

  • Wheatgrass, oat grass and barley grass can be grown in soil or in the FelineBoost Self-Watering Cat Grass Kit.
  • Catnip should be grown separately in soil.

Growing Wheat, Oats or Barley in Soil

Soak the seeds for 8–12 hours, then drain and spread them evenly over 1½–2 inches of moist potting mix in a container with drainage holes. Press them gently into the surface, cover with a very thin layer of soil, and keep the container loosely covered or in a dim location until the seeds sprout. Once shoots appear, move the container into bright, indirect light and keep the soil lightly moist but never waterlogged. The grass is ready for your cat when it reaches approximately 3–5 inches tall.

Growing Catnip

Plant catnip separately in a small pot with well-draining soil. Do not soak the seeds. Sprinkle them over the moist soil, press them gently into the surface, and cover them very lightly. Keep the soil lightly moist and place the pot in a warm, bright location. Catnip usually takes longer to germinate and should be thinned once the seedlings begin to crowd each other. Allow the plant to become established before offering leaves to your cat.

Growing Wheat, Oats or Barley in the FelineBoost Kit

Soak the seeds in cool water for 8–12 hours, then drain and rinse thoroughly. Place the hemp mat over the white insert inside the bamboo or white tray, and slowly pour 2½ cups of water over the mat so it becomes evenly moist; excess water will collect underneath. Spread the soaked seeds evenly across the hemp mat, avoiding thick piles or clumps, then place the blackout cover over the tray for the first few days. Remove the cover when the shoots begin lifting it or reach approximately 1–2 inches tall. The shoots may initially appear yellow, but they will turn green within a few hours after being placed in normal daylight on a kitchen counter—avoid strong, direct sunlight. The grass is usually ready for your cat when it reaches approximately 3–5 inches tall, typically within 5–7 total growing days.

Quick Troubleshooting

Seeds Are Not Sprouting

Check that:

  • The seeds have not dried out.
  • The room is warm enough.
  • Wheat, oats and barley were soaked first.
  • The seeds are not submerged in water.

Grass Is Yellow

Move it into brighter indirect light and check that the roots are not sitting in excess water.

Grass Is Falling Over

The grass may need more light, may have grown too tall, or may need more water.

White Fuzz Appears

Fine white root hairs are normal. Discard the batch if the growth smells unpleasant or appears gray, green, blue or black.

Seeds Smell Sour

Discard the entire batch and clean the growing equipment before starting again.
