Oh, I didn't think you were serious about this actually, so sorry if I answered in a wrong way.
But I actually think its absurd to think that Jesus would manifest him self in a Cheetos or cats fur, and not just absurd, but I also think it is inappropriate to suggest any such thing. Even blasphemous.
I've seen many strange things in clouds for example, but I don't think its anything else then my own imagination making the clouds into something else then clouds. God gave us a good imagination, a mind that can be used for many things, but thinks like suggesting that Virgin Mary has manifested her self in a toast is to make Christianity into some cheap entertainment, the way i look at it. And when I hear about people selling things like this on e-bay and other places, it actually make me angry, and I can't believe that anyone would think that this got anything to do with Christianity.
The bible don't mention any such things. It do mention that Jesus manifested him self in the physical realm to John, but it was not about food or cat fur that time. He had a really serious message for the world, and the way he manifested him self was so powerful that John - even if had lived with Jesus for years - fell down on and got terrified by his power.
Jesus is HOLY, he is no small, earthly thing we can make fun entertainment about.
