How long is recently? A week? A few weeks? Cats are known for needing to stay in the same surroundings to feel comfortable, the reason they are better off with a cat sitter than in a cat hotel when their guardian goes on vacation. So, I agree that he must be upset by the change and it will take him time to settle down. You can't leave your bedroom door open for him to come and go as he pleases? Can your vet prescribe something to calm him until he is settled? It would need to be something like Valium because the Prozac type take weeks to start working.

Poor Chuck! New surroundings and people are annoyed with him.
