Using these Vitakraft treat sticks is easy. Just use the attached clip holder to hang the stick in your cockatiel's cage. Your bird will love pecking at the apple and honey - flavored treat. When the treat part is gone, your cockatiel can still chew on the natural wood center. Make sure to check the stick regularly for any signs of wear or damage. If it looks worn out, replace it with a new one. Keep the treats in a cool, dry place to maintain their freshness. Don't let your cockatiel overindulge; these are treats, so offer them in moderation as part of a balanced diet.
