This grass grows so quickly that you can sow seeds on a Monday and have a ready-to-nibble crop by mid-week, making it endlessly renewable for repeat sowings throughout the year. The dense, tender shoots emerge in just 7, 10 days, and there's no guesswork about readiness, when the grass reaches about 6 inches, it's perfect for your cat to graze. Unlike catnip or other cat toys, this is living, edible enrichment that cats naturally crave, and you control the supply by succession planting in small pots.
Cat grass exists for one purpose: providing indoor cats with fresh, safe vegetation to chew on and consume. Pet owners grow it as a living alternative to dried or processed cat treats, offering their cats the texture and nutrients they instinctively seek. Many cat owners rotate multiple pots to ensure a continuous supply, treating it as a renewable household staple rather than a one-time crop.

Harvest when the grass reaches approximately 6 inches tall, typically 10 days after sowing. At this height, the shoots are tender and at peak palatability for cats. Simply allow your cat access to the pot; they'll naturally graze and consume the grass. Once your cat has grazed the pot down, compost the remaining roots and soil, then replant a fresh batch to continue the cycle.
