This is, by no means, a complete list.  And keep in mind that a pet may still have an allergic reaction to non-toxic plants, so it’s best to discourage them from nibbling at all.  Check your local pet store for suitable repellents for cats and dogs.  Outdoors, you may wish to try Hot Pepper Wax on plants.  Be sure to provide acceptable nibbles for cats, such as cat grass and catnip. If your pet has ingested a questionable plant or substance, contact professional help immediately.

For assistance, you may call the Pet Poison Helpline ( at 1-800-213-6680.  There is a $39.00 consultation fee for this service. Or called the SPCA at 1-888-426-4435.
