A-Z of Houseplants that are Poisonous to your Cats.
85
There are many plants you may bring into your home without realising that they are poisonous to cats. Not all of them will prove fatal if eaten or chewed, but some most definitely can kill your much loved cat. Never assume a cat will instinctively not try and eat a poisonous plant, as all too often cats end up being rushed into the vets suffering from poisoning as a result of chewing on or eating a number of different houseplants. Those of you who read my previous hub about the dangers of Lilies to your cats will know what I am talking about here.
In this article I hope to list most of the more common houseplants that are dangerous to cats so that you can either ensure you don't bring them into your home or at least you can keep them out of the reach of your pets. I am guessing that many of the plants on this list will come as quite a surprise to you.

You are a cat rockstar for publishing this essential information.
Thanks so very much!
I can just agree with lorlie6`s comment. This is excellent Hub. Immediate bookmark. Thank you so much, Cindy!
I can name several of these plants that I've had in my garden, without knowing that the neighbour's cat might get sick if she eats them! The neighbours let their cat wander the neighbourhood during the day while they're at work. Perhaps I should try to plant friendlier flowers next spring! (Although if she didn't eat them this year, what are the chances she will do so next year?)
Thank you for your good advice.
This is another good hub for the protection of cat.
Had no idea there were so many poisonous to cats. Surprising really as carnivores don't target plants, yet they have all these effective defences againsst them.. Interesting hub, Misty. I had a cat very sick with a liver prob. 2 years ago, it may well have been a plant, but the vet. didn't say anything (He's OK now). Bob
Holy smoke! All those plants are bad for cats! Who knew? I must print this list out and send it to my sister. Thanks again, Misty!
Misty, thanks for the great information! I had no idea these were poisonous to cats - every year I get amaryllus and I'm grateful my cat never tried eating it!
This is a great article, very much appreciated by someone like me who has four cats, and two dogs.
*Great hub* Misty! I love plants and pets--so I definitely need to bookmark this one. Thanks for your efforts on this one.
this is good to know although my two cats seem to prefer my artificial flowers!!!
Thank you very much. It was very helpful.
Thank you for this list, including photos. I had no idea there are so many poisonous, yet common houseplants. Every single one I own are on the list. Off to Michael's to buy some silk plants.
this is great my aunt's cat is coming to stay at my Gramma's and she has some different plants so we wanted to make sure the cat was safe thank you so much you are so great for doing all the reasearch and what not thanks again! :D
Thank you very much, I did not realize how many house plants dangerous to cats there were. Now if only stores would warn pet owners of the danger.
Hi Misty,
If I see my cat playing with, but not really chewing or eating, do I need to be concerned with removing these plants from my home? I have a few on the list, Jade, Asparagus fern... If he makes himself sick on them unbeknownst to me, will he eventually stop eating them by realizing at some point that they are doing so?? And how do I know exactly how toxic each plant is?
Thanks.
Before I bought some garden plants, I did a quick search and found Dahlias on the safe lists. I was gifted Basil and Thyme seedlings by the lady I bought catnip from, and decided to do another check, and came across this page as well as the ASPCA (I'm in the UK, we have RSPCA) website saying DAHLIAS are toxic. Now I am freeakingg out, cuz some of the dahlias are in my neighbour's pots and i help her with her little garden as she is blind. I told her that they were safe, now I don't wanna tell her they aren't and I'm afraid that I will bring pollen or something indoors to my indoor only ktties...HELP ME. Do they just have to eat it, or will even a tiny bit on my hands/clothing harm them??? HELP!!! :(:(:(
THANK YOU!!! I will definitely change and wash or even get a hazard suit!!! :D Also, could you let me know if these plants are ok, as the lists are all different and some are not as explantory as yours. Oregano, Coriander, Thyme, Basil, Garlic Chives, Parsley, Miniature Roses, Celosia, and unidentified succulents (definitely not Kalanchoe). These are the indoor ones they sniff alot. A WHOLE LOT. No eating or rubbing, yet. Outside, I have Petunias, Forget me Nots and Pansies...the other places I checked said these were safe, so it would be awesome to have your feedback :) I forget to say awesome post before, as I was in a right old state. *Awesome Post* It's good finding someone close to home and not just generated lists and unchecked regurgitated 'facts'. THANK YOU LOTS :D
Thanks again!
They have four containers of cat grass in various places to deter them, and catnip, so they *may* not eat anything, maybe! I was concerned about having those plants in their environment as a whole, too. Thanks again!
Wow I had no idea lilies could be so toxic! Although my favourite flowers, it is a small sacrifice to give them away for the sake of my cat!! Thanks!
This is very helpfull.I just lost my yellow tabbie his organs shut down due to poison. I know know it was my plants. I can prevent harm to my other pets.
Thanks for making this HUB! Now I know why my kitten is sick! Please tell me what I can do for her to stop the diarrhea and make her well??? Home remedies or do I have to go to vet?
Very well written, concise and helpful article. Featuring the photos is a fantastic plus. I have lost two young cats in the last year due to mysterious circumstances, I am now wondering whether it was due to poison possibly from devil's ivy-what an apt name if so. I am in shock right now, my Tessa died suddenly with no signs of any trauma whatsoever. She did have a strange habit of gnawing on the wood of my dressers in the bedroom, wondered if it could be something toxic in the finish...thank you so much for such a helpful article though. Bless you!
Great info, thanks!
I have a devil's ivy plant, it is up high, but now my kitten found out how to get up there. She seems to want to nibble on it but now eating it. Is this ok or should I just get rid of the plant?? Thanks!!
My three year old cat is in hospital as we speak with Kidney failure. The vet thinks it is the result of her eating from the 'Orange Lily' plant. I cannot see any evidence that she has eaten from any of my plants and I have never seen her eating any either but I have to consider this as being a possibility. Having had cats all my life and also being an avid gardener, I never realised the potential risks. Now after seeing this site, it seems I am going to have to rip up my whole garden and replace everything with cat 'friendly' plants. It should be mandatory that the labels that come with the plants advise whether they are poisonous to our beloved pets or not because if they did then my little girl wouldn't be in hospital fighting for her life right now!
wow, this is incredibly detailed with the pictures. Thankyou very much!
A week ago, my cat died. He was drooling excessively and having seizures. I wish I found this page a long time ago. I have an arum lily plant, after viewing this page, i went to see the plant and sure enough, his little bite marks were all over the leaves and on the flower. Please, everyone, check your plants.
Appreciate the info. Which houseplants CAN we have?
I am confused by the last comment. tomato plants on included in the list but you mention indoor tomatoes. are some tomato plants toxic and other not?
My cat ate something that made her very ill and had to be taken to the vet. After reading this article I saw coleus in your article I have this plant so this must be the plant that my cat has eaten. Now I will get rid of this plant. Thanks a lot for this very useful information
There's nothing her that helps once I bring my cat home from an overnight stay- with length of illness, long-term neurological affects- blindness, etc
I recently put feather grass in my garden & my cats immediately were drawn to it.
Could this be harmful, as it's a decorative plant?
I'm really curious where you got your info on the Orange plant being toxic to cats. I think I have seen this on ONE website and other than that read somewhere that a "decorative" orange plant was dangerous.
Re my last comment: I did find info on the ASPCA website that said that the Essential Oils and some Chemical compounds of the Orange plant can be toxic to cats.
Essential Oils are usually very highly concentrated. It's hard to know what the ASPCA means by that general and somewhat vague description so I am not sure if a nibble on a flower or leaf would make the cat very sick, or kill it. I want to be certain, so I guess this is a good question for a vet. :)
Thank you so much for the pictures & various names used for the same plant. My boys will be safe now & my boys are very curious. I have you in favorites & will be referring back to your site on a regular basis. Again, thank you very much.
Great list, very helpful, esp since 2 flowers on here are ones my girl kitten has taken to chewing on (carnation & primrose) which i hope wont be fatal (she seems fine though thankfully) but i am definitley bookmarking this for future reference! :)
Cannot thank you enough for taking the time and trouble to compile this excellent list with clear pictures. It is so helpful and some garden plants need to be evicted now.
I have been nursing 2 of my babies back to health for 5 days now. Both ate on my devils ivy. I didn't not know this at first because the first one to show signs of illness was one that I have a chronic constipation problem with. I thought was was constipated at first the first day I just watched him, well as a result I almost lost him. He had not ate in 2 days and not drank for a day and a half before I realized something was terribly wrong. I gave pedialyte around the clock for 3 days. He litterally did not move for 3 days. In the meantime I started noticing the other one showing signs and now I am forcing pedialyte down her. My male is better,he is eating on his own but he still will not drink very much. I am still forcing pedialite but he is up and walking and even had 2 bowl movements. Now my female is constipated on top of everything else. She ate a little this morning but will not drink. I knew the devils ivy was poisonous but did not know the signs, thank you. Oh, and just to let you know I am working very closely with my vet on this.

This is great. My cats love to chew on one of my plants. Now I just have to figure out what the plant is. My sister bought it!
