Potpourri poses several risks to pets, particularly birds. The fragrant oils and chemicals used in potpourri can be toxic if ingested or inhaled by birds, leading to respiratory distress or digestive issues. Dry potpourri materials can also be hazardous if pecked at or swallowed, potentially causing intestinal blockages or internal injuries. Given their sensitive respiratory systems, even the airborne particles from heated potpourri can adversely affect a bird's health. Therefore, it's advisable to keep potpourri and similar aromatic products out of reach of birds and other pets to prevent these dangers.
