Designed by actual use, CattleVacBox was designed by ranchers for ranchers. As fourth generation ranchers every part of the CattleVacBox is for a reason. Patented and Made in the USA, our main aspect for the box is safety and organization, and the need to protect the vaccine, the livestock, and the workers.
