Homebrew, Ravenloft: Denizens of Darkness (3.5e)
Shapechanger. The paka can use its action to polymorph into a humanoid form, or back into its true form, which is a feline-humanoid hybrid. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.
Canine Antipathy. The paka has disadvantage on all Wisdom (Animal Handling) checks when interacting with canine creatures, such as dogs, wolves, and worgs. The paka also has disadvantage on all Charisma skill checks when dealing with humanoid races with canine attributes, including werewolves.
Pounce. If the paka moves at least 20' straight toward a creature and then hits it with a melee attack on the same turn, that target must succeed on a DC 16 Strength saving throw or be knocked prone. If the target is prone, the paka can make one melee attack against it as a bonus action.
Multiattack. If the paka takes the attack action, it can either make two rapier attacks or two claw attacks.
Rapier. Melee Weapon Attack: +8 to hit, 5' reach, one target. Hit: 9 (1d8 + 5) piercing damage.
Claws. Melee Weapon Attack: +8 to hit, 5' reach, one target. Hit: 8 (1d6 + 5) slashing damage.
Feline Allies. The paka can establish a telepathic bond with any feline beast within 50' of itself. Once the bond is established, the paka can see through the beast's eyes and hear what it hears as a free action, gaining the benefits of any special senses that the beast has. As a bonus action, the paka can command the beast to perform an action on the beast's next turn, including attack. The bond is broken if the beast moves more than 50' from the paka.
Lick Wounds (3/day). The paka can heal itself or an ally for 1d8 HP.
