It depends on the types of flowers. The ASPCA maintains a comprehensive list of flowers and plants and whether they are toxic or safe for dogs and cats. It's important to remember that certain plants can still be toxic to animals even if they are kept out of reach; pollen and other airborne spores can get into the fur of animals and be ingested during grooming.  If you're ordering flowers for a household that has pets, it's best to stick with a service that allows you to see the types of flowers in the arrangement before ordering. Some brands, like Fresh Sends or subscription services, don't allow you to preview the bouquet before it's sent, which could land you with a bouquet that isn't pet safe. Our top pick, UrbanStems, lists the type of flowers in each arrangement, so you can check to make sure it's safe for your pet. Some brands, like Floracracy, take it a step further and let you completely customize your bouquet so you can be sure to only include plants and flowers that are safe.   Check out our guides on 11 pet-friendly houseplants and the best pet-friendly plants.
