Meat is a kind of food when eating it to the player 1000 xp. When it is not Blobfish / worm / fish animal death, it will produce. Added when deeep.io was republished. It can be eaten by all animals.
Blobfish, Worms, and Fish, and Pollocks do not spawn meat when they die because they do not give enough XP to spawn any meat. However, they do still grant some experience.
