Grass in general has a few things that are good for your cat. it has natrual iodines in it and it is very good for the digestion.

I use it for a cat that has a thing simular to IBS in humans and it hels her alot.

Another thing that helps in the digestion for cats is the brine from veggies in a can. Give it to them each day and you wont get alot of hairballs and such on your carpet or god forbid between your toes as you walk blindly in the toilet in the middle of the night.........lol

I grow it in threes. One they eat now one they ate and one almost ready to eat. The grass grows on well if given a rest period.

Hope this helped,
