Minecraft: How to Breed Foxes

screenrant.com:

Foxes are adorable and playful Minecraft creatures that inhabit the Taiga biomes, and players who manage to find and breed them can make their own Fox ranch. Foxes and their pups come in two colors. Red Foxes are located within the Taiga and Old-growth Taiga regions, cold biomes forested with ferns and spruce trees. Arctic white Foxes conversely reside in Minecraft's rare Snowy Taigas, mountainous biomes with terrain similar to a regular Taiga region but covered in a blanket of snow.

Minecraft Foxes are typically more active during the night but can also be seen scampering about during the day when they aren't sleeping. If a player approaches a Fox, it will immediately dart off, keeping a distance of several blocks away from the player. This behavior makes them somewhat tricky to get close to, mainly because of the rugged terrain of their habitat. However, Foxes will not flee if the player approaches them while sneaking.

To breed Foxes in Minecraft, players will need Sweet Berries, a food item from Sweet Berry Bushes found within the same Taiga regions as Foxes. Be careful when harvesting these berries, as touching the bushes while moving will cause half a heart of damage. After collecting two or more, stealthily approach a pair of wild Foxes in Minecraft. While it isn't necessary, it's highly recommended for players to build a fence or enclosure about the Foxes, so if the player accidentally scares one, they won't be able to wander too far from the other. Then, feed berries to both Foxes to have them breed and spawn a tiny baby pup.

Unfortunately, no matter how many times players breed a pair of wild Foxes in Minecraft, they cannot be tamed and will always flee from the player.
