Grass is the natural source of fiber par excellence. It stimulates your cat's digestion and helps prevent the formation of hairballs. Unlike houseplants, which are often toxic, grass is healthy and perfectly suitable for consumption. With the Catit Senses 2.0 Grass Seed Kit, you can grow your own cat grass in just a few days! The set includes three packets of seeds and three packets of vermiculite, individually packaged for freshness assurance. Why vermiculite? Unlike potting soil, vermiculite allows for a clean working environment. This base guarantees optimal results and easy cultivation.
