Cats are curious creatures that often want to check out anything that enters a home. Unfortunately, many common flowers are toxic to cats; some cause gastrointestinal upset, while others have deadlier consequences.
Don’t give up on keeping plants or receiving flowers, however. Plants and pets often don’t mix but you can still liven up your home with flowers that are relatively safe for your resident cat. Below are flowers that we have verified the non-toxicity of with the ASPCA.
