New structure - "Pet Cemetery". It should consist of a few pets gravestones and few Unearthed graves.
Unearthed grave can be used to ressurect villager, dog or cat for free. It can be done only at night. But as a side effect these mobs can be ressurected as a "raised" mobs - they'll act as a normal mobs for a while but become aggressive after some time.
