Cayenne pepper is a bright red chili powder made from dried cayenne pods and used as a heat-forward seasoning. It is common in hot sauces, dry rubs, marinades, jerky seasoning, and spicy snack coatings. Cayenne is not a nutritional ingredient for pets and is mainly used for heat.
The spicy effect comes from capsaicin, which can irritate the mouth, nose, throat, and GI tract. Cayenne is often combined with garlic powder, onion powder, salt, vinegar, and sugar in commercial blends. Those combinations increase risk compared with a tiny incidental taste of plain powder.
Exposure can happen from table scraps, sauce drips, seasoning dust on fingers, or spilled spice jars. Powder can also irritate eyes and airways if inhaled during sniffing. Keep pet portions unseasoned and clean spills promptly. Spicy snack dust on chips or fries is another common exposure source. Jerky rubs and seasoning blends are additional exposure points. Residue on cutting boards and countertops can also transfer heat compounds to curious pets.
