Cat Deer

The Cat Deer is a passive mob that lives in the overworld. They usually travel in herds sized 2-5. They are the primary source of Pelts and can be ridden and controlled by a player.

Spawning
The Cat Deer is a rare spawn. It only spawns in Jungles, Extreme Hills, Jungle Hills, and Plains. They typically spawn in herds of 2 - 5 Deer and cannot be bred / tamed. They can spawn on just about any block, although tye most commonly spawn on grass.

In Creative Mode, you can spawn the Cat Deer in using the Spawn Egg with the blue-ish color.

Usage
The Cat Deer, like most other native Minecraft entities, can be controlled while on a lead. Additionally, the Cat Deer can be ridden by the player. To mount a cat deer, simply right click it. From here, the player will have full control over the movement of the deer. The Cat Deer while ridden is very fast and is a reliable form of transportation.

Cat Deer cannot be tamed nor can they breed. You can however lure them to wherever you want them to go by holding raw fish in your hand. Once you are within range of a cat deer with raw fish, it will begin to follow you.

Once killed, the Cat Deer will drop anywhere from 0-3 pelts. This makes the Cat Deer an efficient source of pelts, even though it cannot be farmed.

Behavior
The Cat Deer will roam the overworld in herds ranging anywhere from 2-5 dear. (Although it is very uncommon to see a group of one). They tend to walk slowly and cautiously if they are not being bothered. They also choose to stay away from water, but can swim if you lead them to it.

Cat Deer are completely passive to the player and will never attack. If they are hit by the player, they will try to get away. It does take notice to players around it, and may stop to look at nearby players.

As of now, only adult Cat Deer exists and they cannot reproduce.
