Sola balls for birds are soft, lightweight, natural chew toys made from the pith of the Sola plant, perfect for parrots, parakeets, and other small birds to shred, chew, and forage, helping keep beaks trimmed and reducing boredom and stress by satisfying natural instincts. They are eco-friendly, splinter-free, and versatile, easily broken apart for foraging or incorporated into larger toys for beak exercise and mental stimulation, making them popular foot toys.

Amazon sells them. I ordered them From Bonka Birds brand seller. Dakota says thanks!
