Find a rabbit in a biome where they spawn, such as plains, desert, or flower forest
Hold a carrot, golden carrot, or dandelion in your hand
Crouch or move slowly toward the rabbit
Keep the food item visible so the rabbit follows you
Lead the rabbit into a fenced area or pen
Close the opening so the rabbit cannot escape
Use carrots to keep it nearby if needed
Breed rabbits with carrots or dandelions to get more rabbits
Note that rabbits cannot be fully tamed like wolves or cats in Minecraft
