Itchiness and Odd Behavior

Hello...boy has it been a month for Ludo and me!

Just under a week ago, Ludo and I moved from Oregon to Oklahoma. We drove down here. Ludo seemed to handle it pretty well (we stayed at a hotel each night and I made sure he got lots of water and exercise) but now that we are settled something is...off.

He is itchy to start with. Constantly chewing on his feet and scratching. I have been giving him Benedryl twice a day for the past few days until I can get him to the vet but...it just sucks.

The more concerning thing is his behavior. I know he is in a new home with a new person (and me), a new dog, a new cat and an African Grey. I know sharing his home with all of these extras is brand new to him. But he seems exceptionally stressed. He pants real hard and for a good several hours yesterday he refused to come inside but rather laid down up against the back door outside. When he is inside, he only wants to lay in his crate. He plays well with the dog, seems curious about the bird and has already learned to just leave the cat alone. I'm just not sure how to help with this transition.
