We love our pets, right? They’re part of the family. But have you ever stopped to think about how many common household plants could actually be harmful to them? It’s something I’ve had to learn the hard way after my dog decided to munch on a few leaves here and there.
According to the ASPCA, thousands of pets are rushed to the vet each year after ingesting harmful plants. So, let’s take a look at 12 plants that are toxic to our furry friends, and why you should keep them out of reach (or just skip them altogether).
Sago palm

Toxicity: Extremely toxic to dogs and cats
The sago palm is often admired for its beautiful, feathery leaves, but don’t let its looks fool you. Even a small amount of the plant can cause serious liver failure in pets. FYI, the seeds are the most toxic part. Symptoms of poisoning include vomiting, diarrhea, seizures, and even death in severe cases.
Aloe vera
Toxicity: Mild to moderate
Aloe vera is a great plant to have around for its skin-healing properties, but it can be a big no-no for pets. While humans use it for burns and cuts, its sap can cause digestive issues, such as vomiting and diarrhea, in both cats and dogs. In high doses, it can even cause tremors. So much for the healing powers, right?
Dieffenbachia (Dumb Cane)

Toxicity: Severe
Let’s talk about Dieffenbachia, aka Dumb Cane. Not the smartest plant to have if you have curious pets. It contains calcium oxalate crystals that can cause intense burning and swelling in the mouth, leading to difficulty swallowing. Cats and dogs may also drool and vomit. If you’re in doubt about your plant’s name, it’s better to be safe and toss it.
Oleander
Toxicity: Extremely toxic
I know Oleander looks stunning in gardens, but its toxicity is absolutely no joke. Just one or two leaves can be fatal to pets. It affects the heart, leading to symptoms such as drooling, vomiting, and abnormal heart rhythms. So, if you’ve got a pup that likes to sniff around the garden, you might want to reconsider this one.
Ivy (English and Devil’s Ivy)

Toxicity: Mild to moderate
Though ivy can add a nice touch to your home, it’s a pain when it’s chewed on by pets. Ivy contains compounds that cause gastrointestinal distress (think vomiting and diarrhea) when ingested. It’s pretty easy to see how your pet could get into it, so if you’re a plant lover and a pet owner, you might want to keep this one high and out of reach.
Azalea
Toxicity: Severe
Azaleas are bright and cheerful, but they come with a hefty warning. Even small amounts of azalea leaves can cause severe vomiting, diarrhea, and even coma. The toxins in this plant affect the heart and nervous system, which is definitely not something you want to deal with after a fun day in the garden.
Chrysanthemum

Toxicity: Mild to moderate
While your flowers might look pretty on the dining table, Chrysanthemums could cause your pet some serious discomfort. Pets that ingest parts of these plants may experience symptoms like drooling, vomiting, and diarrhea. They also contain toxins that could mess with their central nervous system, which isn’t ideal.
Lily
Toxicity: Extremely toxic to cats
If you’re a cat owner, the lily should be on your no-go list. Just a small amount of the plant can cause kidney failure in cats. Even a nibble on the leaves or petals can be harmful. If you’re unsure which lilies, it’s best to keep all lilies out of your house and garden to be safe. Trust me, it’s not worth the risk.
Poinsettia
Toxicity: Mild
Okay, so the poinsettia isn’t deadly (phew!), but that doesn’t mean it’s harmless. If your pet munches on the leaves, it could experience mild nausea, drooling, and stomach upset. But hey, I guess that’s still better than something lethal. Still, avoid giving your pet any holiday cheer in the form of poinsettias!
Calla lily

Toxicity: Mild to moderate
While they’re often found in decorative arrangements, Calla lilies are toxic to both cats and dogs. The plant contains calcium oxalate crystals, which can cause severe pain when ingested. Expect drooling, mouth irritation, and difficulty swallowing. Maybe choose a different bloom for your vase!
Peace Lily
Toxicity: Moderate
Peace lilies might seem peaceful, but their toxins can pack a punch. If chewed on, they cause swelling and burning in the mouth and throat, leading to nausea and vomiting. Keep these guys off the floor and out of your pet’s reach!
Foxglove
Toxicity: Extremely toxic
Foxglove is a beautiful plant that can actually be deadly to your pets. It contains cardiac glycosides, which affect the heart and can lead to severe poisoning. Symptoms include vomiting, diarrhea, and even heart arrhythmias. So, while it looks great in a flower bed, it’s not worth the risk if you’ve got furry companions running around.
Key takeaway
While it might be tempting to fill your home with lush, beautiful plants, not all of them are safe for our furry friends. From lilies to sago palms, there are plenty of plants that can wreak havoc on your pets’ health. So, next time you’re picking up some greenery for your home, make sure to double-check whether it’s toxic.
Keeping our pets safe means researching, keeping dangerous plants out of reach, and opting for pet-safe alternatives. Trust me, your pets will thank you (even if they can’t say it in words).
