GimCat Hydro Grass
Hydro-Gras contains water-retaining hydro-grains which eliminate the continual need for watering. Instructions for use:

1. It’s this easy: fill the grass bowl to the brim with lukewarm water. The water should be evenly distributed so that the contents of the bowl and the water that is added reach the edge of the bowl. Please do not pour away any of the water, as the water-storing hydro granules absorb all of the water within a few minutes!
2. Place the bowl in a light and warm spot (e.g. a windowsill). Avoid extreme sources of heat (direct sunlight, radiators, etc.).
3. After five to eight days, the Hydro-Grass will have reached a height of around five centimetres. In order to ensure that it remains fresh for longer and reaches its full height, you should now distribute one cup of water (approximately 150 ml) over the grass. You can then give the treat to your cat.
