🐱 Can cats eat this? →Why
Onions belong to the allium family. They damage red blood cells and can lead to haemolytic anaemia. Cooking doesn't remove the risk, and concentrated forms like onion powder — common in gravies, soups and baby food — are especially dangerous.
Signs of trouble to watch for

- Pale gums
- Rapid breathing
- Reddish or brown urine
