The cactus cow spawns in desert biomes. They can also be spawned from a spawn egg on creative mode.
Like the cow, the cactus cow will wander aimlessly on its own. However, when attacked, it will charge and deal 2.5 hearts of damage before ending its attack. When it attacks, it flings the player into the air, which can deal additional damage from fall damage.
You can tame same as cow with wheat you can breed cowctus
