Its standout feature is the self-watering system, which requires just one initial watering, eliminating the daily task of watering and reducing mess since no soil is needed. This kit includes USDA certified organic non-GMO wheatgrass seeds, which are known for their high germination rate, ensuring successful growth most of the time.

The kit's stylish design features a dishwasher-friendly tray with a bamboo surround, making it a nice addition to any home decor. Additionally, it comes with a biodegradable hemp mat, making it an eco-friendly choice. The growing process is simple: soak the seeds, pour water over the hemp mat, cover with the blackout lid for a few days, and then let the grass grow. Within a week, the grass is usually ready for your cat to enjoy.

This kit also has convenient refill packs available separately, allowing continuous growth without any hassle. However, depending on personal preferences, some might find the initial setup slightly tricky, especially if they have never grown plants before. Despite its easy maintenance, the product's large size might not be suitable for homes with limited space. This kit is ideal for cat owners who want a low-maintenance way to provide their pets with fresh, organic grass, though it might not be the best choice for those with very limited space.
