Flowers That Are Poisonous to Cats

By Carrie Epstein

Plants are a visually appealing addition to any home, but cat owners need to pay careful attention before bringing home a plant. Cats naturally tend to nibble on leaves. Placing plants up high is no quick fix because limber kitties will jump up on furniture to chew on leaves when you are not around. The best course of action is to identify which types of plants cause harm to cats and keep them out of your house. There are more than 700 individual kinds of flowers and foliage which can harm cats. Yet there are specific types of plants to keep your eye on and leave at the florist shop.


Lilies are deadly when ingested by cats.

Countless types of lilies are available today including tiger lilies, day lilies and Easter lilies. They pose a particular danger because lilies are a common flower placed in general bouquets so be sure to inspect each bunch. Cats will typically begin vomiting upon consuming these flowers. They will stop eating, become sluggish and can reach full kidney failure within 36 to 72 hours after lily ingestion.
