Cinnamon brooms are generally not considered safe for cats. While cinnamon itself is technically non-toxic to cats in small amounts, cats lack the liver enzymes required to properly break down cinnamon compounds, which can cause gastrointestinal issues and more serious toxic effects if ingested in larger quantities. Cinnamon essential oils used in cinnamon brooms pose an even higher risk, as they are highly concentrated and can cause symptoms such as muscle weakness, lethargy, respiratory issues, and potentially liver failure. Additionally, the strong scent of cinnamon brooms can be overwhelming and irritating to cats' sensitive noses, and chewing on the broom could irritate their mouths. Therefore, it is best to keep cinnamon brooms out of reach of cats to avoid accidental ingestion or inhalation exposure to the essential oils, which could be harmful or even deadly.
