well, he has gotten through the "transition period". He is definitely part of the family now. For the first few weeks, he shredded a stack of magazines (luckily, no GRMs were harmed in the making of this post), a couple books, 4 pairs of my girlfriends flip flops, and the bottom 6 inches of our vertical blinds.
He has not "messed" in the house in about 3 weeks, hasn't torn anything up in about 2 weeks, and has slept quite calmly in the middle of the bed for the last week or so as well.
he is still as adorable as ever. he lays next to me on the couch when I play Forza!
