What to Do if Your Pet Eats a Poisonous Plant

If your cat ingests a poisonous substance, you will usually need to provide some type of immediate treatment at home, and then rush your cat to the vet. Your first step should be to phone your veterinarian or the ASPCA National Animal Poison Control Center for advice, so be prepared to give the proper name of the plant. It's also a good idea to keep a feline first aid kit on hand for emergencies.

Call the Vet

You will be given specific instructions on what kind of first response treatment to give your cat in an effort to stabilize the situation. You should then immediately take your pet to the veterinarian, even if it means paying for emergency fees. Some plants are so toxic to cats that they can be fatal or cause severe damage to a cat's internal organs, such as the kidneys. In cases like these, it is better to err on the side of caution and get your pet the help that he needs.

Play It Safe With Poisonous Plants

In addition to silk plants, there are several different safe plants for cats. Many local pet stores carry seeds or plants already started that you can purchase and take home. Not only are these plants visually pleasing, but they will also satisfy your cat's desire to chew, while still keeping him safe.
