Since an ocelot does not wear armor, you can use this data tag to list 4 items that you want the ocelot to drop when it is killed (4 custom drops)

Syntax
ArmorItems:[{Count:1,id:item}, {Count:1,id:item}, {Count:1,id:item}, {Count:1,id:item}]

Example
{ArmorItems:[{Count:3,id:redstone}, {Count:1,id:golden_horse_armor}, {Count:2,id:iron_ingot}, {Count:7,id:gold_ingot}]}

The drop chances for each of the 4 items listed in ArmorItems. A value of 1.0f means 100% chance of the item being dropped when the ocelot is killed, 0.5f means 50%, 0.2f means 20%, and so on.

Example
{ArmorDropChances:[1.0f,1.0f,1.0f,1.0f]}

A number that specifies the right half of the UUID for the ocelot (use UUIDLeast and UUIDMost to target/find a particular ocelot in the game)

Example
{UUIDLeast:-6645587150281567948L}

A number that specifies the left half of the UUID for the ocelot (use UUIDLeast and UUIDMost to target/find a particular ocelot in the game)

Example
{UUIDMost:4420078606457655279L}

ocelot (The entity value used to represent an ocelot in the EntityTag or Passengers tag)

Example
{id:ocelot}

The mob that is riding on the ocelot. Use the entity value for the passenger mob
