Using the Catit Senses 2.0 Indoor Cat Grass Planter is easy. First, buy the Catit Senses 2.0 Cat Grass Kit (43162W) separately as the seeds and soil aren't included with the planter. Fill the deeper bowl with the soil from the kit. Then, scatter the wheat and grain seeds on top of the soil. Water the seeds gently, making sure not to over - water as the drainage holes are there to help. Place the planter in a spot where your cat can easily reach it but avoid areas where it can be easily knocked over. Keep in mind that the special grid cover is there to stop your cat from digging. As for maintenance, check the soil regularly to see if it's dry. If it is, give it a light watering. Once the grass grows, your cat can nibble on it to aid digestion and prevent hairballs. Remember, this planter is made of BPA - free materials, so it's safe for your cat.
