Cat grass for indoor cats is important as it helps their digestion. I can’t remember the name of the product, but any pet store will have cat grass that is ready for you to add water and grow. My local grocery store sometimes sells already grown cat grass and my cats love it. I’m surprised a grocery store would do this. I guess people, like me are buying it. It only costs $3.00 – pretty cheap.
In the summer I will dig up or cut some grass from my lawn and give it to my cats. I just have to make sure that the grass is free from pesticides.
