This cage doesn't included tetherspout.You can buy your tetherspout here or anywhere.
The cage will be attached with a 3mm gauge/thickness shaped integrated tetherspout hook, and a 2mm gauge/ thickness unshaped integrated tetherspout hook. Because the position of each person's urethral orifice is different, the shaped hook may not be very perfect, so the unshaped hook will be attached and you can shape it by yourself(use pointed nose toothless pliers). You can have the fun of making your cage perfect by yourself.
