*Keen Smell.* The guardian cat has advantage on Wisdom (Perception) checks that
rely on smell.

*Dutiful.* The guardian cat is ordered to protect something valuable belonging
to its master.  It will never leave its position, nor will it attack, unless it
is attacked first, or someone other than its master tries to take something from
the room it guards.  If a fight breaks out, it will not pursue any attackers who
try to leave empty-handed, and will return to its initial spot, licking its
wounds.
 
*Alert.* As soon as a fight breaks out with the guardian cat, its master is
notified.

*Nine Lives.* The guardian cat has nine lives, represented by the nine stripes
on its back.  Each time it is reduced to 0 hit points, up to the ninth time, it
is instantly reborn stronger than before and loses one stripe.  It reappears in
the same spot as before with full hit points, and all conditions except grappled
and restrained are removed.

With each rebirth, the guardian cat grows in size.  On its 3rd life, it becomes
a Small creature.  On its 5th life, it becomes a Medium creature.  On its 7th
life, it becomes a Large creature.  On its 9th life, it becomes a Huge creature.

With each rebirth, add 3 hit points to the guardian cat's maximum.  Starting at
its 7th life, add 5 hit points instead.

With each rebirth, the guardian cat's Dexterity is increased by 1, and its
Strength by 2.

Each day, the guardian cat regains a life and reduces in size and strength.
