Cat Spirit
Cat Spirit · mob, rare · Catgirl & Catboy Mod
A Cat Spirit is a see-through, floating cat-person in a white or Siamese coat. It is the rarest mob of the mod: its spawn weight is 1, against 3 for a Bakeneko.
Where it appears
In plains, sunflower plains, meadows, forests, taigas, snowy plains and cherry groves, where the light level is 4 or lower. It doesn't spawn on Peaceful. When it gets bright, the spirit fades away.
It can't be hurt or killed. Any hit makes it fade.
The gift
Right-click it with a small flower, for example a dandelion or a poppy. The spirit takes one flower, gives you Nine Lives for one in-game day (20 minutes) and fades.
Nine Lives cancels your next death once: you are left with half a heart and get Regeneration II for 45 seconds and Absorption II for 5 seconds. It doesn't work against the void or /kill. More on the effects page.
With Jade installed, looking at the spirit shows a hint about the flower.
