Which Plants Are Poisonous To Cats?


I love coming home to a nice bouquet of flowers specifically my new favorite obsession sunflowers! Guess who else enjoys a good batch of flowers to mess around with?

My cats.

It would appear that my cats have an undeniable obsession of the flowery variety because I always find bits and pieces of leaves and petals scattered around the dining room table. Luckily for all involved the type of flowers we usually have around are Roses, so no need to alert the media!

There are a variety of plants that can be lethal to cats so it’s super important to know which plants to stay away from and which ones are ok to bring into the home. The following is a list of some of the more common plants that are extremely harmful to cats.

For a complete list of all plants that can be harmful to your kitty please visit the ASPCA’s website.

  • Lilies
  • Azalea
  • Tulips
  • Marijuana
  • Oleander
  • Sago Palm
  • Peace Lily
  • Yew
  • Cyclamen
  • Amaryllis
  • Schefflera
  • Kalanchoe
  • Autum Crocus
  • Chrysanthemum
  • Castor Bean
  • Pothos
  • English Ivy


What To Look For

If you happen to bring home any one of the plants listed above and you suspect that your cat may have taken a nibble or two you can double check by looking for signs of vomiting, diarrhea, drooling, lethargy, and/or difficulty breathing. Not every cat will show these signs and some may even show different signs altogether. Just be sure you keep an eye on your cat and if you see any unusual behavior from them then it’s safe to assume something is not right and it may be related to the ingestion of the plant.

 In Case of An Emergency

Take your cat to the vet immediately.

It doesn’t take long for the toxins of some of these plants to take effect and there have been cases where cats have been seriously affected, as in the case of lilies, if you wait too long.

It’s also important to be able to identify the type of plant your cat has consumed as this will help the staff at the veterinary hospital determine the best form of action. If you don’t know what the plant is but you have a sample of it then make sure you bring that along with you.

As always prevention is key! So if you have any lilies hanging around your backyard then you’d do best to have them removed ASAP! The same precaution should be made for plants or flowers within the home. And if you just love, love, LOVE lilies and couldn’t fathom not having them in your home then maybe you can opt to buy some sort of lily oil or fragrance to put around your house.

    Great advice! It seems like just about everything is toxic =/ The kennel manager where I used to work took home a Lilly that a client brought us for Easter one year. Well, her cat ended up eating it and became very sick from it… He was OK, but it did cost a lot for all of his care I’m sure.

    • ugh, that sucks! I can’t keep any flowers around these days, my cats just destroy them and make the biggest mess. They must smell pretty good but the rest of us can’t appreciate it because they have to hog it all up lol
