On Break Cactus

A Cactus is one of several naturally-occurring blocks of vegetation in Minecraft. It can only be grown on sand, and can grow to a maximum of 3 blocks tall. If a player or mob touches a cactus, they will begin to take damage as long as they are in contact with the cactus. A cactus will not shear sheep. Any items that come in contact with a cactus will be destroyed. Unlike most plants, Cacti do not need light or water to grow, and are inflammable. Cacti cannot be placed on Sandstone. Blocks touching a cactus block will be destroyed. Blocks can however be placed horizontal to cacti. Cacti are abundant in the Dessert Biome.

Because cactus does not require water to grow, and causes damage to mobs, it is commonly used as a barrier of defense for forts.

Cacti can be stacked as high as the player wants, but can not be found this way in nature. To destroy a large stack of cacti, destroy the bottom block first, the whole stack will collapse.
