Bless you for rescuing Jinx! You do not have to worry. Whenever a cat is moved, he scopes out a safe spot and hides until he is sure there are no predators or dangers. Some cats will not even eat or potty for a few days till they acclimate.
You can speed up this process by applying his scent to things.
Rub a damp cloth on his pads and neck where there are scent glands. Then rub it on windowsills, doorways and furniture.
Once he smells himself he will feel more comfortable.
Don't pull him out and force him. Just leave his food, water and litter within reach. Let him come out when he is ready.
You can tempt him with some tasty food like tuna or chicken. To a cat, food is LOVE and they CAN be bribed!
Please let me know how things are going.
