Black Pepper
Piper nigrum
Also known as: Peppercorn, Ground Pepper, White Pepper, Piperine
Black pepper (Piper nigrum) is the most common table spice. It is not poisonous to cats, but it is a strong irritant and cats should not eat it. The compound that gives pepper its heat, piperine, irritates the lining of the mouth, nose, eyes and digestive tract. Cats are far more sensitive to it than people are. A trace of pepper in a bite of seasoned food is unlikely to cause more than a sneeze. Larger amounts, such as licking up spilled pepper or eating heavily peppered food, can cause drooling, vomiting, diarrhea and loss of appetite. Inhaling ground pepper causes sneezing, coughing, watery eyes and nasal irritation, and pepper in the eyes causes burning and redness. Black pepper is sometimes used as a cat repellent for exactly this reason, which is not recommended. If your cat has eaten or inhaled pepper, offer water and wipe any powder from the face. Rinse the eyes gently with saline if pepper got into them. Contact your veterinarian if vomiting or diarrhea continues, if breathing seems laboured, or if eye irritation does not settle.
