⛔ Unsafe Known to be harmful or toxic. Keep it away from your pet.

No, onions and garlic are unsafe for cockatiels. Even small amounts can cause significant harm. You should keep these items completely out of reach and avoid feeding them to your bird under any circumstances.

🚨 Emergency: Yes — contact your veterinarian immediately.

💡 Why

Onions and garlic contain thiosulfates, which damage red blood cells in birds, leading to hemolytic anemia. Cockatiels have a faster metabolism than mammals, making them particularly sensitive to this toxin. Symptoms include weakness, lethargy, and pale mucous membranes.

🩺 What to do

  1. Remove any remaining onion or garlic from the cage and surroundings immediately.
  2. Monitor your cockatiel for signs of lethargy, weakness, or difficulty breathing.
  3. Contact an avian veterinarian immediately if ingestion is suspected or symptoms appear.
Important: this is for reference only and is not veterinary advice. If your cockatiel may have eaten or touched something dangerous, contact your veterinarian immediately.

❓ Common questions

Can I use garlic to treat mites in my cockatiel?

No, do not use garlic or onion products for mite treatment. These compounds are toxic to birds and can cause severe health issues.

Is a tiny piece of onion in a salad safe?

No, even trace amounts can be harmful. It is best to prepare separate, bird-safe foods without any allium family members.

What should I feed my cockatiel instead?

Offer a balanced diet of high-quality pellets, fresh vegetables like bell peppers or carrots, and limited seeds. Always wash produce thoroughly.
