Even non-toxic plants can upset the stomach when consumed, particularly in animals with sensitive stomachs. Other plants may even have chemicals or pesticides on their leaves, which can further harm animals. Always try to prevent pets from eating indoor plants.

It is advantageous for pet parents to be familiar with the names of every plant in their residence, including both nicknames and Latin names.

The best thing you can do in this situation is to identify the plant in question before your pet eats one of your nontoxic plants, or if your pet eats a plant that might be poisonous while out for a walk or while visiting a friend.

Many dangerous succulent species would be difficult for veterinarians to identify. It is best to be familiar with the plants in your house, and if a pet ingests one you are unsure of, look it up right away to check for potential toxicity and call your veterinarian right away.
