Swings make your bird feel like it is perched on a swaying branch in the wind giving some movement within its cage. Therefore it is important that the swing is large enough & it meets the requirements of your feathered friend. The sisal swing is special due to its finest top quality lime perch. This can help your bird to keep their beak & claws sharp & short like they would in the wild. The bird´s feet muscles will also be kept in better shape helping to avoid pressure sores. The bow-shaped frame is tightly wrapped in thin cotton woolen cord. This lends the swing a natural look. In addition there is a thick play rope on the end of the perch & allows the bird to play whilst still on the perch leading to unforgettable moments of joy. A wonderful natural swing that will give your feathered friend countless hours of fun.
