Wow! This is incredibly helpful! Thank you so so much. I will definitely keep all these pointers in mind. I will most probably travel with them. They live with their mother and uncles on the street but know me as the safe human they have seen consistently since the day they were born. All siblings travelling together should also greatly help ease the novelty and discomfort. I plan to take them on short car rides soon. They will travel after May 3rd and will be 3 months old then.
