Catgrass :
The Grass Cat Oats, 'Avena sativa', is an important part of a cat's diet. We have chosen the best grass for cats, Oat Grass. It provides nutrients and is a good digestive aid. Plant this grass to keep your cats from eating potentially harmful house plants. It assists cats with furball elimination and provides certain vitamins and mineral to the cat's diet.
Place Oat Grass seed by a window and the window light will supply enough light to get Oat Grass to the 2 to 4 inch height needed for cats to start munching down. Normal household temperature is ideal for germination and plant growth. Place seeds in potting soil to start the growth process. Use a container that is over 6 inches in diameter so the cats will not knock over the container.
