The WEE Bander™ can be used on calves, kids, and lambs. When stretched, the WEE Loop™ opens to approximately a 1 ½” triangle. If the testicles fit, it works. The WEE normally works well on calves up to six weeks of age. Castration with the lightweight WEE Bander™ is effective and bloodless, and requires no manual cutting or crimping of the loop. The WEE Bander™ can also be used to dock tails on sheep and for removing small horns.
