How to Plant Cat Grass


Cats are well known for eating indoor plants and outdoor grass. It seems that the need for vitamins and minerals in a cat's diet drives it to graze. Unfortunately, houseplants can make cats very sick, which includes kidney failure and death. Planting cat grass is a healthier alternative to offering houseplants to munching cats. Cat grass is basically a mixture of common oat, wheat and rye grass. Cat grass offers benefits to cats by aiding digestion, adding roughage to their diet and eliminating hairballs. This type of cereal grass is planted and grown indoors at any time of the year.

Step 1

Wash a shallow container, 6 to 8 inches in diameter, with soapy water. Rinse the container in a solution of one part bleach and nine parts water to disinfect the container. Let the container air dry for a few hours.

Step 2

Poke holes in the bottom of the container with a screwdriver, if there are no drainage holes present. Punch out one hole for every square inch along the bottom of the container.

Step 3

Fill the container with commercial potting soil leaving 1 inch of space from the container rim. Tap the container on a countertop to settle the soil, and add more soil if needed.

Step 4

Sprinkle the cat grass seeds evenly over the soil surface. Be generous with the seeds to create a lush stand of cat grass. Cover the seeds with 1/4 inch of soil. Spray the seeds with water until the soil is thoroughly wet.

Step 5

Place the cat grass container in a bright location out of cat reach. Keep the soil damp by spraying with water daily. When the grass leaves are 2 inches tall, place the container in a location of bright light where the cat can find it.
