What toxic plants should you keep away from your cats? And what plants are safe alternatives? This is super important for all cat owners to understand so you can make a safe environment for your cat.

What symptoms to expect if a cat eats a toxic plant

If a cat eats a toxic plant, the consequences can vary depending on the type of plant and how much they eat. You may simply have a sick cat for a few hours but, at worse, the cat can suffer from serious illness and even death. Toxic plants can disrupt the healthy function of your cat's gastrointestinal tract and other internal organs, which can quickly become life-threatening.

Cat owners: if you suspect your cat has nibbled on a poisonous plant, here are some symptoms to look out for.

  • Difficulty breathing

  • Abdominal pain (you might notice when you pick your cat up)

  • Twitching or trembling

  • Drinking water excessively

  • Difficulty swallowing or drooling

  • Fainting or coma

Call your local pet poison helpline if you suspect that your cat has eaten a poisonous plant.

Needless to say, don't wait to take your cat to the vet in case of a medical emergency. Time is of the essence, so move quickly if you suspect your cat needs medical attention.

Why is my cat chewing on my house plants?

If your cat is chewing up your plants, it’s possible that they are looking for folic acid. Outdoor cats can get their daily dose by eating grass. However, grass can be more difficult to come by for indoor cats.

As such, it’s a good idea to plant a fresh pot of cat grass if you own a house cat. This will contain enough folic acid and most cats absolutely love it. A word of warning: your cat won't digest the grass and will often throw it up. However, don’t worry, that’s normal! Just clean it up - all sorted :-)

There are many places to purchase fully-grown cat grass for your house cat to munch on. Check out your local florist, plant stores, and pet supply stores. It’s also good fun to grow cat grass yourself! You can purchase seed trays and seeds at your local garden store, hardware store, or online.

What healthy snacks can I feed my domestic cat instead?

There are plenty of alternative snacks to feed your cat. For example, you can always offer your cat raw or dried meat, fish, or kibble treats. It's always best to feed your house cats meat instead of vegetables, as this is much healthier for your cat's body.
