Do you know which plants are poisonous to your dog, cat, or other pet? Keep your fuzzy
friends safe! Here is a list of the more common plants and flowers that may be dangerous for
your pet.

We all enjoy our flowering plants. However, pet owners need to be aware that some plants
are toxic if their animal has a hankering to eat them!

You may already know that daffodils cause stomach upsets or vomiting (or worse) if you pet
eats any parts of the plant. Many lilies are also considered extremely toxic; this can be more
of a danger because lilies are often brought inside as houseplants or holiday decorations.

But you may not know that foxglove and aloe vera are quite poisonous, too.
We’ve highlighted some of the most toxic plants below. However, there are more than 700
plants with toxic substances that are dangerous to dogs, cats, and other pets if ingested, so
always make sure that you know whether any new plants you bring home are toxic or not!
