This is a handmade item. It can be used for a wide range of small to medium-sized parakeets (budgies, Java sparrows, lovebirds, cockatiels, etc.). You can use it in your preferred way, either attached to the side of the cage or the ceiling (it's fixed, so it won't swing). We hope your beloved bird can enjoy spending time with you! ☆*:.。. o(≧▽≦)o .。.:*☆
