Meerkat Practical Uses - Player and Hostile Mob Detector

Meerkats were part of the 2018 Biome Vote as part of the desert update. Despite losing the vote, the losing biomes were confirmed be added later on, so here are a few features that the meerkat mob could have when implemented, based on traits of real meerkats:

1. When real meerkat families are foraging for food, they will have several meerkats act as sentries to watchout for predators. If any predators are spotted, the sentry meerkat will make a warning sound to alert the family. In Minecraft, this could be implemented so that a meerkat will make such a warning sound when any hostile mob is within a certain range. This could be used to alert a player that one or more hostile mobs are near by. If a player breeds two meerkats, the baby will trust the player and will also make alert sounds when untrusted players are near. If a meerkat burrow in sand is nearby, they will sleep during the night and not alert.
2. Real meerkats typically eat insects or adjacent, like spiders and millipeds. In Minecraft, they could attack these types of mobs (silverfish/endermites/spiders), or these mobs are afraid of meerkats and run away, similar to creepers with cats.

Example cases:

• When building within villages, one zombie can ruin everything by infecting/killing villagers, having a meerkat there to alert players right away could be invaluable.
• Players can create security systems for their bases using trusting meerkats making alerts at unknown players, detected by Skulk Sensors, to trigger redstone systems.
