You might know that some plants are toxic to pets, but what about flowers? Whether you're making an arrangement of freshly cut spring blooms or just received a birthday bouquet, if you have a pet at home, you'll want to double-check that certain flowers aren't in the mix. Believe it or not, if your dog or cat ingests even a small amount of a toxic flower, it can cause health issues ranging from GI upset to life-threatening organ failure.
You can try to keep toxic flowers and plants out of your pet’s reach—but that’s easier said than done with cats, who investigate everything and anything you bring into your home. If you know you have a little explorer, or if you have a new pet and aren’t sure about their habits, keep the most dangerous plants out of your home altogether. And keep a close eye on pets outdoors if you have any of these planted in your garden.
Now, you obviously can’t watch your furry friends 24/7. If you suspect your pet has nibbled on a toxic plant—even if you’re not entirely sure—call your vet ASAP. It’s always better to be safe rather than sorry. Just remember that any plant can cause diarrhea or vomiting if ingested in large enough quantities, so it's best to keep your pets from munching on flowers and flowering houseplants altogether.
Read on for the 12 flowers that are most toxic for animals (domesticated or wild!).

Lily

If you have cats, one plant you should never have in your house is lily, even in bouquets. Lilies can cause irreversible kidney failure. Even a few grains of pollen or drinking water from a vase that contains lilies can be fatal for your cat. Lilies are not toxic to dogs.

Tulip

The entire plant is problematic, but the highest concentration of toxins is in the tulip bulb. If ingested, tulips cause intense GI upset, drooling, loss of appetite, seizures, and cardiac abnormalities. Keep the bulbs away from pets when you’re planting your spring garden, and keep indoor potted tulips away from your pets.
