are all plants in the lily family poisonous to dogs and cats?
Howard County Maryland
All plants in the lily family (Liliaceae) are poisonous to cats but not dogs, according to the ASPCA.
I looked at the website you posted. It only states plants in the Lilium genus not entire family.
So then you are stating only plants in the Lilium genus are poisonous.
You should check with your vet to be sure; generally, plants in the same family have similar defensive compounds that are meant to deter herbivores (like plants in the Milkweed and Nightshade families, for instance) and so probably have similar risk to pets due to the shared presence of those compounds. Commonly-used garden plants that are in the Lily family include Allium (ornamental and edible onion, garlic, chives, etc.), Tulipa (Tulips), Fritillaria (Fritillaries), and Tricyrtis (Toad Lily).
