Black cats in Minecraft are rare variants that can be found in two main locations: Witch Huts in Swamp Biomes and during full moon nights in newly generated villages. To find them, players should look for Witch Huts in the northwest corners of Swamp Biomes or explore new villages at night during a full moon, where there is a 50% chance of spawning black cats.
To tame a black cat, players need to collect raw fish (preferably raw cod or raw salmon), approach the cat slowly, and feed it the fish until hearts appear above its head, indicating it has been tamed. Once tamed, the cat will follow the player and can scare away Creepers.
Breeding black cats requires two tamed black cats and feeding them raw cod or salmon near a Witch Hut to produce black kittens. Additionally, players can summon black cats using the command /summon cat ~ ~ ~ {variant:all_black}, provided cheats are enabled. Tips for finding black cats include exploring swamps at night, being patient, and ensuring a safe space free from hostile mobs.
