While looking around for the kitchen to feed yourself and go to sleep, you stumble upon your grandfather's office, and curiosity takes the better of you, and you check out his desk.
On his desk you see a series of contracts, all seem rather uniform, all of them are lifetime contracts with no escape clause, they seem to be for purchasing animals for the zoo... except the phrasing are strange. The animal species is filled in the blank, they range from mundane animals to dragons to sphinxes ... but no werewolves, weretigers, or were-anything ironically in spite of your previous amusement, guess not everything can be about were-creatures. Heh, you'd think this was a joke, but you do vaguely remember seeing some fantastic beasts... MAYBE when you'd last visited.
However... there's mention of 'retroactively no being remembered as human', 'agree to being zoo property till your natural death'... There was a slew of names, and large sums to be paid to next of kin or a charity, others looked to be made under duress or force.
The clause on the contract explicitly mentions upon your grandfather's death, that the zoos assets, including the undersigned, would be reassigned to your ownership.
You shake your head, you could figure this out in the morning.
"Master? your server is sorry, she did not expect you to arrive so late, this humble servant apologizes."
Huh? You turn around, and see a humanoid tigress, covered in stripped fur, two breasts, not six, two, and wearing a white maid bonnet, and fingerless white gloves and toe-less white socks, but otherwise naked, sans a red ribbon around her neck with a bell. Though you guess clothes would be too hot with all that fur.
"You are master are you not? Your grandfather showed me your photograph. This servant's name is Missie, how may she serve you?" The tigress, Missie, asks again, bowing.
"Uh... yes... that's me..."
"Oh! It's a pleasure to meet you master! I hope I am able to service you as I serviced your grandfather, the previous master!"
"Master?"
"Oh yes master, just as others are under contract to embrace the joy of being being zoo exhibits, your maid too am under contract to be loyal and obedient to the best of her ability. It is your servant's pleasure and honor to serve you." Missie explained, she never stopped smiling.
