Erick Rowan's Cage: 3 bold predictions for what's inside 

#2 An animal of some kind

Could Erick Rowan be hiding some kind of animal inside his mysterious cage?

Erick Rowan seems like he's the kind of man who would keep animals that he finds out in the wild as pets, much like worms and snails and creepy crawlies that regular people would class as insects.

At the same time, the addition of the blood last night on RAW suggests that it could have been something much bigger that is related to Rowan's past life. Since Rowan would come to the ring wearing a sheep mask at the beginning of his WWE career, it's easy to see Rowan keeping the heart of that sheep inside his cage instead.

Perhaps Rowan believes that he can draw power from the creature and so he keeps a part of the animal in the cage, which is why there is blood attached to it. Rowan could still be connected to his Wyatt Family roots even though The Fiend is over on SmackDown which means that there could be something supernatural about this whole affair so don't rule out the fact that the animal in there could be still alive and being controlled by Wyatt.
