Even the toy on amazon has issues. Our birds have enjoyed pulling the paper threads and scattering them all over their home cage for more than 10 years.
This totals several hundred budgies and other grass parakeets. Yes, the potentials are present, and we only place them in supervised cages. Our little guys love to play with this toy and we have had "0" problems. I would not put it in a nest box cage or a large walk in flight, It is so worth the giggles and laughs while watching the adventures. I would suggest an alternative. Place the toy in the cage only when a responsible adult is available and then remove the toy and shredded paper until the next time. This will also keep the toy as a fresh experience. For us, this toy has brought many happy hours sharing with our budgies.
