Can cats eat onions?
No · Toxic / avoid
No. Onions is not safe for cats.
Why
Onions (raw, cooked, powdered or in sauces) belong to the Allium family. They damage cats' red blood cells and can cause anemia. Cats are more sensitive to Allium plants than dogs.

Contact your vet. Signs such as weakness, pale gums or red-brown urine can appear days later.
Always check with your vet if your cat has health conditions, and see the ASPCA list of people foods to avoid.
