Plants Safe For Cats – The Extensive List of Plants Both Safe and Toxic to Cats

Plants Safe For Cats – The Extensive List of Plants Both Safe and Toxic to Cats

✔ This article was written by a licensed veterinarian.

There are over 400 plants that are known to be toxic to cats. However, there are over 550 plants known to be non-toxic to cats, or “plants safe for cats.” 

Both of these lists can be quite overwhelming to digest. So, we put together a guide on which common house plants and flowers are safe for cats, as well as those toxic to cats.

Although cats are obligate carnivores, they tend to investigate and eat plants at times. They often knock plants over too, but that’s a discussion for another day. You’ve probably seen your cat eat grass or small plants around the home if you’ve taken them outside. 

When I was working at a veterinary clinic, a cat owner came to us with a kitten that was shaking, hyper-salivating, and lethargic. It appeared that the kitten had nibbled on some ornamental plants that she was keeping in the house. Despite our best efforts, the kitten did not survive. Since then, I have always kept my plants away from my cats’ curious eyes and teeth. You can never be too careful.

I know it can be hard to keep an eye on our cats constantly and see what mischievous things they are up to. So, for your peace of mind, we have put together an extensive guide so you can be sure you’re not putting your cat in harm’s way! 

We cover the following items in this post:

Common Plants Safe For Cats (Non-Toxic)

This tastes fake, Susan. Just like your “homemade” brownies. I’m not buying it.

When you bring a new plant home, always make sure to check the name of the plant to determine its toxicity. You can find the full list of plants listed as non-toxic for cats by ASPCA here.

If your cat is more curious by nature or the plant has an attractive smell, your cat can nibble on it just to taste it. Some plants attract cats so much that they won’t stop nibbling; they will continue eating the whole leaf or flower. Or they may just knock it over and leave the mess for you!

Regardless of toxicity, the ASPCA recommends that cat owners keep their pets from nibbling on any houseplants. 

Below are the most common house plants that are safe for your cat. This list doesn’t include all safe plants but it provides an overview of the most common houseplants.

  • African Violet (Saintpaulia spp.) – Also known as Cape Marigold.
  • Areca Palm (Chrysalidocarpus lutescens) – Also known as Golden Butterfly Palm, Cane Palm, Golden Feather Palm, or Yellow Palm.

Similar to the list of safe plants above, the below list doesn’t include all toxic plants but provides an overview of the most common houseplants that are toxic to cats.

The most common plants that have been reported to have systemic effects on cats and/or intense effects on their digestive system include:

  • Asters
  • Freesia
  • Gerbera
  • Evergreen rose – All plants of the Rosa genus are classified as non-toxic to cats.

Common Poisoning Symptoms in Cats

The symptoms related to poisoning in cats can differ as they depend on what the cat has consumed and how much of it they’ve consumed. Symptoms can be as minor as some aches and the desire to be secluded, and as major as difficulty breathing and emergency trips to the vet. Below are some common symptoms associated with a cat consuming something poisonous:

  • Hypersalivation
  • Tremors
  • Skin irritation (excessive itching)
  • Drooling
  • Loss of appetite
  • Nausea
  • Twitching
  • Seizures
  • Incoordination
  • Increased heart rate
  • Irritability (more so than usual)
  • Depression (the desire to be alone, weaker body language, change in vocalization)
  • Difficulty breathing
  • Increased thirst
  • Coma
  • Inflammation around the mouth
  • Vomiting
  • Excessive urination
  • Diarrhea
  • Panting
  • Dilated pupils

In rare cases, plants can be so toxic to cats that even if they ingest a small amount, it can kill them.

Whether we are talking about plants or anything else with toxic potential, in general, the severity of the clinical manifestations depends on the amount of poison ingested. You know your cat best, so be on the lookout for any changes in behavior. 

Many cats prefer to be alone when feeling ill, so it can be hard to determine that they are sick if you aren’t around them often.

How to Keep Cats Out of Plants

A bad cat. Plants safe for cats
I’m not speaking until my lawyer is present. Or until you bribe me with delicious treats.

The easy answer is to limit the plants you have to only those proven to be safe for cats. If your love for plants is similar to your love for cats, and you need both in the home, you should take the following precautions to protect your cat:

  1. Create barriers to your plants. This can be done by ensuring plants are in rooms that the cat can’t access. Or, if necessary, place the plant in a room where the cat has access, but in an area the cat can’t get to. These can be extremely tall structures the cat can’t scale or can’t get to by jumping from another structure.
  2. Weight your plants. Put heavy objects, like stones, in your plants to weigh them down so cats can’t knock them over.
  3. Create a negative association. This one isn’t ideal, but if your cat can get to the plant, begin to make that event an inconvenience. For instance, spray them with a water bottle. 
  4. Use a spray to deter cats. There are air sprayers like the PetSafe SSSCAT Spray Deterrent that assist in keeping your cat away.
  5. Make it smelly! Not for you, but for the cat. There are certain scents most cats hate, and you can use these to protect both the plant and the cat. Examples include lavender, rosemary, thyme, eucalyptus, orange, lime, grapefruit, and pepper. You can place these scents around your plants to deter your cat(s).

If all of the above fails – it may be time to get rid of that plant!

What to Do If My Cat Eats a Poisonous Plant

If you suspect your cat ate any part of a toxic plant, it is best to: 

  1. Contact your veterinarian immediately
  2. If you are unable to get in contact with your vet, contact the Animal Poison Control Center. Their information can be found here, or call (888) 426-4435. They are available 24/7, 365 days a year.
  3. Keep your cat away from the plant.
  4. Document as much information as you can gather on the incident. Note the time you think your cat ate from the toxic plant, the symptoms you’re seeing, and anything else worth noting.

Do not make your cat vomit!

In general, the clinical manifestations appear about 20-30 minutes after ingesting a toxic plant.

Keep in mind that any plant material your cat consumes can cause gastrointestinal disorders.

Final Thoughts on Plants Safe For Cats

Cats are mischievous creatures that may try things for the sake of trying them. This can be concerning when you have a house full of plants, or a garden that your cat has access to, as many plants can be dangerous for cats.

The best thing you can do is be vigilant and informed. If you can avoid an incident by simply ridding your home of the poisonous plants, that is your best bet. No matter how cute you think your plants are, or how much you enjoy plants in general – the risk isn’t worth the reward. 

You brought this little, vulnerable, creature home. Now you must protect it!
