It's going great! They jumped into one cage together during playtime! I decided to house them together. The little one nibbles at the big ones fur, then he does the same to the little one! Is this normal?
The first time my guys went into their cage together overnight, I slept on the couch beside the cage with a pair of oven mitts in case the older one went for the little one (again). Glad your intro seems to be going much better than mine did.
