Cat grass is a general term for young cereal grain grasses, most commonly including barley, wheat, oat, or rye, grown specifically for feline consumption. Offering this fresh greenery can function as a digestive aid for cats, helping to stimulate the gastrointestinal tract. The fiber content in the grass assists in moving ingested hair and other indigestible matter through the gut, supporting natural hairball control. This simple project provides safe enrichment for indoor cats, satisfying their instinctual urge to nibble on plants.
Supplies and Preparation
Growing cat grass requires selecting materials that ensure the final product is safe for consumption. Begin by selecting a container that is shallow (two to four inches deep) with adequate drainage holes to prevent waterlogging. The seeds are often sold as a “cat grass mix,” typically a blend of oat, wheat, and barley seeds.
The growing medium needs careful consideration since your cat may ingest the grass and substrate. Standard potting soil is acceptable, but it must be certified organic and free from synthetic fertilizers or pesticides. Alternatively, use a soilless medium like coir or specialized hydroponic mats for a cleaner, dirt-free environment.
The Planting Process
Fill the container with the growing medium, leaving about half an inch of space from the rim. Cat grass is sown densely to achieve a thick, lawn-like mat and prevent the cat from easily digging up the soil. Scatter the seeds generously and evenly across the surface, ensuring they are almost touching.
After scattering, cover the seeds with a thin layer of the potting medium (one-eighth to one-quarter of an inch deep). If using a soilless mat, press the seeds firmly into the surface. Conclude planting by thoroughly watering the container until the soil is saturated and water drains from the bottom holes.
Germination and Initial Growth
To promote rapid sprouting, loosely cover the container with clear plastic wrap or a dome immediately after planting to create a humid microclimate. Place the covered container in a warm location (70 to 75 degrees Fahrenheit), keeping it out of direct sunlight during this phase. This warmth and humidity trigger the seeds to sprout quickly.
During the initial three to seven days of germination, maintaining consistent moisture is more important than providing light. The soil surface should always feel damp, but never soggy, as excess water can lead to mold growth. Once pale sprouts emerge, remove the plastic covering to allow air circulation. Moving the container to a bright spot with indirect sunlight will encourage the blades to develop their rich green color.
Harvesting and Continued Care
The cat grass is ready to be presented to your feline friend when the blades reach a height of four to six inches, which usually takes about seven to ten days from planting. You have the option of setting the entire container down for your cat to graze from or trimming small bundles of the grass with clean scissors for a controlled snack. If you trim the grass, cut the blades just above the soil line to allow for potential regrowth.
To extend the life of your cat grass, move the established container to a cooler location with moderate light once the initial growth surge is complete. Water the grass less frequently after the first week, allowing the top layer of soil to dry slightly between waterings to prevent root rot. Trimming back any yellowing or dead blades of grass will encourage fresh growth, though a single planting typically provides fresh grass for two to three weeks before a new batch is needed.
