Summarize this article in one sentence.
It will take your rabbit time to become accustomed to a new location, whether it’s temporary or permanent. He may not be extremely friendly or seem like himself during the adjustment period because of the stress of travel. In time, he will start investigating his surroundings out of curiosity – just be sure to let this happen on its own and don’t force him. As soon as possible after the transport, put him back in his normal cage or set up his room like it was at home. Offer the same type of food he was eating before, and give him back some familiar toys. Spend time with him talking and petting him just like you did at home. Because travel is stressful to rabbits, you’ll want to keep an eye on his health after the transport. Because rabbits are prey animals, they tend to try to hide their illnesses and injuries. If your rabbit seems sick, you’ll need to bring him to a vet as soon as possible. Signs of illness include:  Teeth grinding (especially paired with hunched posture – is a sign of pain) Tilted head Open-mouth breathing Blood in urine or anywhere in his cage/home Limping or paralysis Enlarged abdomen that seems painful to the touch Vocalizing (crying) Decrease in eating or drinking that lasts more than a couple of days after travel Drooling, slobbering, loss of chin hairs (all indicate a dental problem in a rabbit) Discharge from nose, sneezing or coughing, difficulty breathing (indicate a respiratory infection) Change in stool (diarrhea or decreased stools) Hair loss, itchiness, flaking skin, or lumps on the skin Biting, growling, or attacking (indicates substantial pain in a usually gentle animal)

Summary:
Give your rabbit time. Recreate his normal environment as much as possible. Watch for signs of illness.
