Minecraft wiki entry for Gathering_resources_on_peaceful_difficulty, associated text: Fortunately, rotten flesh is not very useful – you will be fine if you never acquire it in a Minecraft world. However, if you do have a certain purpose for rotten flesh, such as to feed your wolf, it can be obtained in a few ways without killing any hostile monster. Like bones, rotten flesh can be found in desert temple chests, jungle temple chests, dungeon chests, and woodland mansion chests. Rotten flesh can also be obtained from igloo basement chests, which is useful if you have a snowy tundra or snowy taiga biome near spawn. Unfortunately, not all igloos have basements, so you may have to go through many igloos to find rotten flesh, or try to find a desert, jungle, or a dungeon. Rotten flesh can also be found in Shipwreck supply chests, but again, not every shipwreck generates a supply room (this part is usually broken). Rotten flesh can also be found in village temples, but only the desert village temple has a chest, so it's better to look for desert villages than other villages. Lastly, rotten flesh can also be found in underwater ruins chests. Rotten flesh also has a 1.2% chance of being obtained when fishing. However, like for bones, a fishing rod requires string, which is rather expensive when on Peaceful difficulty. However, most of the places where you can find rotten flesh, you can find string as well. Rotten flesh is also given by a tamed cat as a gift, but only with a 16.13% chance. You can find stray cats in villages, and tame them using any raw fish.
