Our cats are experienced movers. Saphirah has moved 4 times (including a move from Louisiana to Georgia), Chloe has moved twice, and Samson has moved once. They have all adjusted very well each time. They get a little worried during the packing stage because things are a little different. Once we have arrived in the new house, it just takes a couple of days for them to settle in. They will be fine. BTW, our Samson has a personality similar to your Wilber. He has made the adjustment just fine.
