List of Poisonous Plants for Cats and Dogs

| Modified on Aug 31, 2021

There are over 700 plants that could kill or injure your dog or cat!  Some could well be growing in your yard right now.  Here is a comprehensive list of plants that could injure or kill your beloved pet.

The list included here cannot possibly begin to cover every single poisonous plant in existence.  Also, some of these plants are much more toxic than others. It is important to use your best judgment when determining whether or not these plants should remain in your home or garden. Consider your personal situation and the normal behavior of your pets.  If you keep any of these plants in areas that cannot be accessed by your pet, or if you have a pet that has never bothered with getting into your plants in the past, then it is likely you shouldn't have a problem with keeping those particular plants in a home with pets.

The most important thing for you do to when assessing your current plant situation is to dig a little bit deeper and find out exactly how toxic certain plants can be and how they can affect your animal.

Autumn Crocus

Posted by Shannon C. (Phoenix, AZ) on 06/10/2009

I think it is important to note that Automn Crocus is not an actual "crocus" which is confusing because some crocus bulbs due come up in the fall. here is the wikipedia link: which includes a photo for distinction.

Buttercup - poisonous to dogs? Formerly my Border terrier was grass grazer, but lately she has turned to buttercup leaves. Of course, I stop her. However, is there something missing in her diet that makes her look for this plant?

My border terrier also likes to eat buttercup leaves and I was wondering the same thing about something missing in her diet. I try to stop her from eating the leaves but she has never shown any ill effects from doing so! Let's hope someone can throw somw light on this - she seems to ignore other plants.

Buttercup is poisonous to dogs, cats, and horses.

Replied by Susieq

To Katiem: they already know it is poisonous, the question was if their dogs were missing something from their diet because the dogs are intentionally trying to eat the buttercup.

Looks like it is the buttercup flower only that is poisonous--the leaves seem to be OK?

Replied by Theresa
(Mpls., Mn)

Hey Polarbear4!

The entire plant is toxic - leaves and flowers - as they contain the poison protoanemonin. When the leaves and flowers are dried they poison is nullified. Protoanemonin poisoning varies by the amount consumed -a few leaves may not have any effect while eating an entire plant may produce a big toxic reaction.

A dog *might* be tempted to eat buttercup leaves and flowers for therapeutic reasons, ie homeopathy - where like cures like.

Cats Claw Vine

Posted by Concerned Puppy Momma (Chandler, Az) on 04/15/2013

My fiance and I have recently received a pit bull puppy as a gift and she loves to wrestle, tug, and play in the cats claw vines growing on our patio. My biggest concern is these may be harmful to her. I have searched multiple sites and none of them list this vine anywhere. I dont want to just take it as a sign that there is no harm from these without being sure... Can anyone give me some information? Maybe I'm missing something. Thank you.

My dog ate chinaberries and is lethargic throwing up. Is there any home remedies?

Replied by Theresa
(Mpls., Mn)

Hey Candice!

You should take your dog to the vet as this is life threatening.

If you cannot get to the vet, you can try feeding your dog activated charcoal - you can get it at the aquarium store and grind it to a fine powder. See if you can get your dog to take this either mixed in with some broth or home made doggie pedialyte. Bentonite clay would also apply if you cannot find the activated charcoal [or vice versa].

Again, my first choice for chinaberry poisoning is the vet.

So very sorry you are dealing with a sick pup. Theresa is right. Take your dog to the vet. However, just a quick note from my personal experience with China berry trees (which we call ball bearing trees for obvious reasons). We have multiple such trees on our property, and have for 26 years. Every one of our many dogs over those years has munched on them with no ill effects whatsoever. One dog, who I have now, loves them: eats them at the green stage, and really loves them when they dry. My burros also eat them without consequence. it at all possible there is a different cause for your pup's distress? All the best.

Croton Plant

We were given a Croton Plant and we have 2 cats. We want to make sure they are not dangerous if our cats decide to chew on the leaves.

Replied by Nicole.poisonous2pets

If the croton plant you are refering to is a codiaeum species, it is moderately toxic. It can cause eye irritation, dermatitis and eczema with contact alone. If consumed, it can cause a burning sensation to the mouth, stomach pain, nausea, vomiting and diarrhoea. In can also cause more severe symptoms such as haemorrhages of the heart, and degradation of the kidneys and liver. I am a horticulturist who writes on plants which are toxic to dogs and cats and all my information has been verified by a veterinarian so the information is correct. Just be careful about this plant around your pets.

Daylilies, Lilies and Iris

Is an Iris leave poison for a puppy/dog? I didn't see it on your poison list..

EC: Kelly, thanks for asking! We're updating our list of poisonous plants to add iris, daylilies and lilies. Many (but not all) varieties are toxic to dogs and cats.

Poisonous Plants to Dogs:

Since ponds have become so popular, I'm trying to find a list of decorative grasses that can be used around dogs. My neighbor's 2 bichon puppies became very ill from chewing on one of the following plants: Feather Reed, Miscanthus, Blue Oat, Big Twister, Bee Balm, & Japanese Blood Grass. I've been trying to get info on these plants & have become frustrated trying to find a straight forward simple answer. And for any plant nurseries out there - you should have a list available to all of your customers & ask if they have pets BEFORE you recommend plants.
Thanks for any information you can share with me.

Our dog Mindie a cavalier spaniel is currently staying overnight at our vets after she ate miscanthus sinensis, she has been constantly vomiting and poorly. We did not know at first what had caused this problem but reading your site has helped us detect the cause and inform the vet of our info regarding the grass. We are still waiting to hear if she is ok but thank you for this valuable information.

Hi, I would like to know if Japanese Blood Grass is poisonious to cats? What would the symptoms be? My cat has been eating it and I have found vomit outside with grass in it. Ma

I frequently walk my dogs through the scrub desert east of the Santa Rita mountains along the Santa Cruz river. Upon browsing this site to find out what might be harmful to them, I find a LIST!!!!! No pictures!!!!

Obviously, this does me no good. I would have to know ALL the plants I come across in order to look up and see if they are harmful. A list is useless to me. Where can I find pictures?

Whoever stated they applied aloe vera to their dogs' hot spot did not check with the Animal poison control" website.

Aloe Vera is Toxic to your dog and to cats etc. when ingested.... Hope band Aid guarantees stickability...

I'm not a vet just someone who double checks all remedies that claim to heal....

Is honeysuckle poisonous to cats? My wife recently brought in cuttings from a Yellow Honeysuckle (Lonicera Flava) and a Japanese Honeysuckle (Lonicera Japonica). I noticed one of our cats eating the leaves. Can this make him sick?

EC: Honeysuckle is mentioned on various forums as being toxic to cats, but no varieties are listed.

I have a planter that has Ivy in it. I called the flower company that sent it and asked what kind of ivy it is. The reason being I have four cats in my house and I know that some ivys are poisonous. After searching on line I think I have it narrowed down to an ivy called Hedera a. Gloire de Marengo. I can't find any information on whether or not this is toxic to cats. I have it up high now so they can't get at it. But eventually I will need to put the plant where it can get sun. Thanks so much!

EC: Here are photos from a google search if anyone is interested to see what this type of ivy looks like:

Hi, I have a lantana bush in my backyard. My dog eats the leaves and then throws up, I noticed that you all say they are poisonous. Is she just eating them to make herself throw up? Also, my backyard is filled with azaleas, wisteria, wild black cherry, and a huge yew tree. Should I worry about these plants around my dog...she never eats those but the lantana and she also eats camelia flowers...when she eats the lantana she vomits then she's ok. What should I do?

I have a dog that ate Lantana. I almost lost her. I carried her to the vet and her urine was like ice tea. I moved all of my lantana plants to the front yard where she can not get to them.

I sprayed twice something on my dog's paw that has lavender as one of the ingredients, and he licked it while I was clipping his nails. The following day he was having difficulty standing up. I didn't automatically think it was the spray but after he refused to eat beef liver, which he loves, I realized there was something wrong. He will drink water, lots of it, but barely eats. I gave him a capful of hydrogen peroxide 3% to make him throw up and he did within minutes but then one side below his neck became enlarged as if filled with air. It doesn't seem painful to him when I touch it, but he is still lethargic.

Be careful with lavender around your dog. Do not let them ingest it.

To Cat Lovers, Our newly kitten ate rose petals from my potted miniature rose bush and started coughing up blood non stop. We rushed him to the emergency room and the doctor stated the petals were eating away his stomach lining. Luckily, they pumped his stomach and were able to treat him back to health. My cat spent 48 hours in the hospital w/ an iv and $1200 later was able to come home. I do not see roses listed on any site as poisonous. They are highly toxic. Please add roses to your list so more cat lovers will know. Thanks!

Replied by Chris
(New York, NY)

Roses are an edible flower, our cat loves rose petals, not to mention that roses are used in drinks and other foods. I would have to guess that your cat was sickened by some kind of spray (either a leaf food or a pesticide) on the roses, as is very common with roses purchased at nurseries that don't specify if they do or do not use pesticides. also, many many professional gardeners use sprays as a matter of habit. You should certainly ask your vet what they think, but i also hope it helps you not be afraid of roses in the future.
