No, cats should not eat icing due to potential health risks.
Icing is typically made from sugar, which cats do not need in their diet, and can lead to weight gain and dental issues. Frosting usually contains ingredients such as chocolate or artificial sweeteners such as xylitol, which are toxic to cats. It’s best to avoid giving cats frosting or other sugary foods. Instead, stick to a regular, balanced diet of cat food for optimal health.
