Stuck indoors all day, cats are often looking for things to do. And one of them is to nibble on your plants. Why not cultivate some house plants that your cat will enjoy without you having to worry about toxicity? A few might even do double duty as garnishes on your own foods or as seasonings in sauces or soups. And in some cases, plants that can be grown indoors might even provide a health benefit for your feline pet.
