Schrödinger's Cat (3.5e Monster)

The now famous cleric-wizard Schrödinger was a disciple of Snuggles. His familiar was poisoned by cyanide and became the first Schrödinger's cat. Unfortunately, the familiar's name was lost to the annals of time.

A Schrödinger's cat is spontaneously created when a wizard’s cat dies from being poisoned with cyanide. The same cyanide that caused its death now flows through its saliva.

During the day, a Schrödinger's cat appears as a normal living cat. Not even a true seeing spell will reveal its undead nature. A detect aura spell reveals it as a normal neutral cat. More importantly, a Schrödinger's cat is unaffected by a cleric’s turn or rebuke undead ability during the day.

Only at night does the Schrödinger's cat reveal its neutral evil alignment and undead status. As soon as the sun sets, the Schrödinger's cat undergoes a frightful transformation, becoming unnaturally thin with decaying flesh and missing tufts of fur. It will attack anyone other than its master.

Even in undeath, Schrödinger's cats are loyal to their masters, regardless of alignment, and will not harm them unless forced by magical or supernatural means.

Combat
Schrödinger's cats prefer to sneak up on their prey. They rely on their poisonous bite to kill prey and defend themselves.

Poison : Schrödinger's cats have a poisonous bite. Initial damage is 1d6 points of hit point loss; secondary damage of 1d6 Con. A successful save halves the damage (DC is 13 and includes a +2 racial bonus). The save is constitution-based.

Skills: Schrödinger's cats have a +4 racial bonus on Climb, Hide*, and Move Silently checks and a +8 racial bonus on Jump checks. Schrödinger's cats have a +8 racial bonus on Balance checks. They use their Dexterity modifier instead of their Strength modifier for Climb and Jump checks. *In areas of tall grass or heavy undergrowth, the Hide bonus rises to +8.

Note: The Improved Familiar Feat will not allow a spellcaster to take a Schrödinger's cat as a familiar. A cat familiar that undergoes this transformation ceases to be a familiar.
