When being tamed, in both creative mode and survival, Ocelot does become a pet, however their skin remains as the untamed ocelot. The game sees the ocelot as tamed, however it does not match with visual from the player. The pet does not change into any of the three breeds of cat, and stays as a wild ocelot. I am also unable to make the cat sit. The Player cannot interact with the ocelot other than with the standard food mechanics for all tamable animals. The game still recognizes that the ocelot is tamed, even though visibly it does not appear so, outside of the standard hearts above the entity. Name tags still work fine.
Works as intended. Cats and ocelots are separate mobs now. To get tamed cats, you have to tame stray cats that spawn in villages. Ocelots are no longer tamable. You can feed them to make the trust you (meaning they won't run away), but they can still do what they like.
