Now that Spring is upon us and many are trying to grow a green thumb, I thought I’d share some of this basic info with you in hopes of preventing any pet-related tragedies.
(Note: I’m pulling this info from the ASPCA Animal Poison Control Center)
17 Common Poisonous Plants
Lilies
Members of the Lilium spp. are considered to be highly toxic to cats. While the poisonous component has not yet been identified, it is clear that with even ingestions of very small amounts of the plant, severe kidney damage could result.
Marijuana
Ingestion of Cannabis sativa by companion animals can result in depression of the central nervous system and incoordination, as well as vomiting, diarrhea, drooling, increased heart rate, and even seizures and coma.
Sago Palm
All parts of Cycas Revoluta are poisonous, but the seeds or “nuts” contain the largest amount of toxin. The ingestion of just one or two seeds can result in very serious effects, which include vomiting, diarrhea, depression, seizures and liver failure.
Tulip/Narcissus bulbs
The bulb portions of Tulipa/Narcissus spp. contain toxins that can cause intense gastrointestinal irritation, drooling, loss of appetite, depression of the central nervous system, convulsions and cardiac abnormalities.
Azalea/Rhododendron
Members of the Rhododenron spp. contain substances known as grayantoxins, which can produce vomiting, drooling, diarrhea, weakness and depression of the central nervous system in animals. Severe azalea poisoning could ultimately lead to coma and death from cardiovascular collapse.
Oleander
All parts of Nerium oleander are considered to be toxic, as they contain cardiac glycosides that have the potential to cause serious effects—including gastrointestinal tract irritation, abnormal heart function, hypothermia and even death.
Castor Bean
The poisonous principle in Ricinus communis is ricin, a highly toxic protein that can produce severe abdominal pain, drooling, vomiting, diarrhea, excessive thirst, weakness and loss of appetite. Severe cases of poisoning can result in dehydration, muscle twitching, tremors, seizures, coma and death.
Cyclamen
Cylamen species contain cyclamine, but the highest concentration of this toxic component is typically located in the root portion of the plant. If consumed, Cylamen can produce significant gastrointestinal irritation, including intense vomiting. Fatalities have also been reported in some cases.
Kalanchoe
This plant contains components that can produce gastrointestinal irritation, as well as those that are toxic to the heart, and can seriously affect cardiac rhythm and rate.
Yew
Taxus spp. contains a toxic component known as taxine, which causes central nervous system effects such as trembling, incoordination, and difficulty breathing. It can also cause significant gastrointestinal irritation and cardiac failure, which can result in death.
Amaryllis
Common garden plants popular around Easter, Amaryllis species contain toxins that can cause vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia and tremors.
Autumn Crocus
Ingestion of Colchicum autumnale by pets can result in oral irritation, bloody vomiting, diarrhea, shock, multi-organ damage and bone marrow suppression.
Chrysanthemum
These popular blooms are part of the Compositae family, which contain pyrethrins that may produce gastrointestinal upset, including drooling, vomiting and diarrhea, if eaten. In certain cases depression and loss of coordination may also develop if enough of any part of the plant is consumed.
English Ivy
Also called branching ivy, glacier ivy, needlepoint ivy, sweetheart ivy and California ivy, Hedera helix contains triterpenoid saponins that, should pets ingest, can result in vomiting, abdominal pain, hypersalivation and diarrhea.
Peace Lily (AKA Mauna Loa Peace Lily)
Spathiphyllum contains calcium oxalate crystals that can cause oral irritation, excessive drooling, vomiting, difficulty in swallowing and intense burning and irritation of the mouth, lips and tongue in pets who ingest.
Pothos
Pothos (both Scindapsus and Epipremnum) belongs to the Araceae family. If chewed or ingested, this popular household plant can cause significant mechanical irritation and swelling of the oral tissues and other parts of the gastrointestinal tract.
Schefflera
Schefflera and Brassaia actinophylla contain calcium oxalate crystals that can cause oral irritation, excessive drooling, vomiting, difficulty in swallowing and intense burning and irritation of the mouth, lips and tongue in pets who ingest.

A LIST OF HOUSEHOLD PLANTS THAT ARE PET-FRIENDLY
Want to send flowers to someone? *Be sure they are safe for pets! Here are some suggestions from 1-800-FLOWERS.com that include options like dendrobium orchids, violets and gerbera daisies, and more.
(Use promotion code ASPCA when ordering and 1-800-FLOWERS.com will donate 10 percent of the net proceeds from your purchase to the ASPCA!)
Please note that while the flowers shown are considered to be nontoxic, it’s important to keep in mind that even “safe” plants can produce minor stomach upset if ingested.
Here’s a list of the most common food hazards you should be aware of!
Experts at the ASPCA Animal Poison Control Center urge you to avoid feeding the following foods to your pet:
• Alcoholic beverages
• Avocado
• Chocolate (all forms)
• Coffee (all forms)
• Fatty foods
• Macadamia nuts
• Moldy or spoiled foods
• Onions, onion powder
• Raisins and grapes
• Salt
• Yeast dough
• Garlic
• Products sweetened with xylitol
Additional foods that may be potentially hazardous.
Ibuprofen and Aspirin
Ibuprofen can definitely be toxic to dogs and other pets—even in small amounts. Depending on the dose ingested, significant gastrointestinal damage or even kidney damage could result. Drugs, including non-steroidal anti-inflammatories like aspirin, can cause serious or potentially life-threatening problems, depending on the dose involved.
In fact, many drugs that are beneficial to humans can be harmful or even deadly for pets. Never give your pet any medication without first speaking with his or her regular veterinarian.
If you feel that your pet needs pain relief for any reason, get in touch with your veterinarian—if you have not already. Your vet can direct you regarding the best dose to use or, if necessary, can prescribe a different pain reliever.
And while most human medications are contained in child-proof bottles, these containers are not pet-proof. Pets can easily chew and break open packaging, so medications should always be stored in a secure cabinet above the countertop.
WHAT TO DO IF YOUR PET IS POISONED
• Don’t panic. Rapid response is important, but panicking can interfere with the process of helping your pet.
• Take 30 to 60 seconds to safely collect and have at hand any material involved. This may be of great benefit to your vet and/or APCC toxicologists, as they determine what poison or poisons are involved. In the event that you need to take your pet to a local veterinarian, be sure to take the product’s container with you. Also, collect in a sealable plastic bag any material your pet may have vomited or chewed.
• If you witness your pet consuming material that you suspect might be toxic, do not hesitate to seek emergency assistance, even if you do not notice any adverse effects. Sometimes, even if poisoned, an animal may appear normal for several hours or for days after the incident.
Call the ASPCA Animal Poison Control Center or your vet immediately.
The telephone number is (888) 426-4435. There is a $60 consultation fee for this service.
Be ready with the following information:
- the species, breed, age, sex, weight and number of animals involved
- the animal’s symptoms
- information regarding the exposure, including the agent (if known), the amount of the agent involved and the time elapsed since the time of exposure.
Have the product container/packaging available for reference.
Please note: If your animal is having seizures, losing consciousness, is unconscious or is having difficulty breathing, telephone ahead and bring your pet immediately to your local veterinarian or emergency veterinary clinic. If necessary, he or she may call the APCC.
Be Prepared
Keep the telephone number of the ASPCA Animal Poison Control Center—(888) 426-4435—as well as that of your local veterinarian, in a prominent location.
Invest in an emergency first-aid kit for your pet. The kit should contain:
- a fresh bottle of hydrogen peroxide, 3 percent USP (to induce vomiting)
- a turkey baster, bulb syringe or large medicine syringe (to administer peroxide)
- saline eye solution
- artificial tear gel (to lubricate eyes after flushing)
- mild grease-cutting dishwashing liquid (for bathing an animal after skin contamination)
- forceps (to remove stingers)
- a muzzle (to protect against fear- or excitement-induced biting)
- a can of your pet’s favorite wet food
-a pet carrier
Always consult a veterinarian or the APCC for directions on how and when to use any emergency first-aid item.

Awesome Info Lorie, thank you!!!!!!!! You Rock!!!!!!!!!!!!!!!

Awesome information, thanks Lorie! There were certain poisons on that list about which I had no clue, like the raisins/grapes thing… Any idea why those are considered toxic? I also love the fact that 1-800-flowers has pet-safe options, and that is awesome of them to offer that (and give cash to the ASPCA, too!).
I wanted to add a couple of things based upon my experience, if you don’t mind… For one, if your dog or cat ingests a small amount of regular milk chocolate, this isn’t really a big deal. The ingredient that is toxic is called theobromine, and milk chocolate contains very little of it. However, dark chocolate contains a higher concentration of theobromine, and is considerably more dangerous. Also, many diet pills contain theobromine and related compounds, and in much higher amounts than chocolate, so beware of these. Second thing—aspirin is safe in moderate doses for dogs; however, tylenol (acetaminophen/paracetamol) and ibuprofen are not safe in any dose. Last but not least, if you do have to force-feed your dog/cat hydrogen peroxide, do it in the bathtub, as it results in almost immediate copious vomiting, and it’s hell to clean up, lol.
Thanks again, Lorie. :)

Thanks for the added info! There is some reference to that on the site, but I didn’t want to completely bombard everyone with a 4-foot long journal entry. :P
As for the grapes… check out The Wrath of Grapes for some interesting info.
I wish I had known about the grape thing years ago – I used to have a dog that LOVED them and we could never understand why he would eat them then vomit.
Check out the article though… it’s interesting and definitely a good reference!
