Can they eat it? / Cinnamon
Can dogs and cats eat cinnamon?
A sprinkle is harmless; powder in the nose or a lot of it is not.
Cinnamon is not toxic, but inhaled powder causes coughing and breathing trouble, and large amounts irritate the mouth and can lower blood sugar. Cinnamon rolls and sticks are the usual problem.
Coughing, drooling, vomiting, low blood sugar in quantity.
Offer water, skip the next meal, and call your vet if vomiting or diarrhea lasts more than a day or your pet seems unwell.
Careful for dogs means: fine in a small amount, prepared as described, and not for every pet; the details say when to skip it.
