Signs of Intelligence

It likes to eat this big peanut butter stick, and I found it buried it completely.  It doesn't seem to be eating much else but I have seen has some.  The food doesn't seem to be going down, though, still the same amount it looks.  It must be just enjoying the peanut butter stick.

I was shining light in its house a lot, and I can't move the house in the cage because it's attached.  Next time, I saw it covered the whole with bedding so I couldn't do it.
