I think that snow leopards should be added (revision of my previous post)

I think it would be really cool to add another feline mob to Minecraft, specifically the snow leopard, snow leopards will spawn on mountains and they will hunt goats, they will sneak up on them like an ocelot and pounce on them like a fox. Their claws will have snowflake particles on them and they inflict the freezing debuff, they can be tamed using blue ice and they will follow you around, and protect you, because this mob will be a fantasy creature like the nautilus, sometimes when it is attacking a mob they will drop one of their claws. This claw can be used in a brewing stand to make a potion of freezing resistance. The reason for this is because the freezing debuff is overpowered in pvp because you need to sacrifice an armor slot for leather armor which makes you much weaker, or you need to constantly set yourself on fire. The reason for using blue ice to tame the snow leopard is because it uses blue ice to imbue their claws with ice magic, they will be a rare spawn, about as rare as a Zombie nautilus because they are powerful. they can be bred by using raw mutton, They would be a fantastic addition to the winter drop of 2026, and people have been wanting a big cat added to the game for a long time, to go along with Minecraft's philosophy of real world animals not being hostile in the game, and snow leopards natural avoidance of humans in real life, they will run from you and only attack if they are attacked. This won't be an addon, but an actual feature for vanilla.
