This swing can be hung anywhere in the cage. It provides some exercise for the gliders as they explore it and climb on it. The perch itself has a very rough sandy surface that can be a real help in keeping the gliders’ nails in shape. The sandy surface is very durable and can be scrubbed without damage to the surface. Depending on how much your gliders play on it, there may be a big benefit in that it may help keep their nails trimmed.
