/teleport command for teleporting ocelot into the void has issues

The bug

If you set up the command teleport @e[type=ocelot] ~ -512 ~ on repeat and spawn an ocelot with a spawn egg, the ocelot, visually, does not get teleported but will take void damage.
Furthermore, with teleport @e[type=ocelot] ~ -1 ~ the ocelot stays where it is spawned and retains a hitbox.
