"Cats like to chew green things. Be sure to provide something safe for your cat to chew on."
If you suspect that your cat has ingested any plants poisonous to cats or other toxic substances, you must act immediately.Call your veterinarian or local emergency animal clinic. It's best to take a sample of the plant or other poison along with you to the veterinarian so they will know what your cat has ingested and they can treat him or her accordingly.
Giving Your Cat His Own Plant to Chew
Giving your cat her own "plant" to chew is another solution and is actually beneficial for your cat's digestion and help her get rid of unwanted matter, such as hairballs.
Many pet supply stores and even grocery stores now sell cat grass. Catnip, sage, thyme and parsley are also safe for your cat to chew in moderate amounts. Wheat (not "wheat grass") and oat-grass sprouts are also safe and tasty for your cat.
Ordinary lawn grass should be avoided, as it has razor-sharp spines that can cut your cat's mouth and even harm her digestive tract.
Your cat may vomit a greenish liquid with some plant fragments after eating a safe plant, such as cat grass. Don't worry. This is normal, as long it isn't excessive or constant.
Growing a "Plant" for Your Cat to Chew
You can even grow plants specifically for your cat’s enjoyment. If you choose to grow your own cat grass, catnip, sage, thyme, parsley or other safe "plants," be sure to use sterilized potting soil and untreated seeds. You should not use soil from your outdoor garden.
If you grow catnip, it's probably best to grow this in a room inaccessible to your cat. You can give your cat a generous handful of fresh or dried leaves every week or two. Catnip has a powerful (yet, safe) chemical that most cats love. Organic catnip is the healthiest for your feline friend.
About two-thirds of all cats are mad about catnip. It's a genetic preference. After a deep whiff, your cat will dance, leap, prance, tumble and purr in ecstasy. Don't worry. It's not addictive! Catnip is completely safe. But if you give catnip to your cat too often, it may lose its appeal over time.
