I'm so glad to hear that they arrived safely. I hope that their vet exams and tests go well and they calm down quickly. I've learned that if you have an overweight cat that you should feed it less dry and more canned food because canned food has much less carbs in it than canned. You don't want them to lose weight too quickly though or they can get fatty liver disease. When my Ziggy was getting overweight my vet told me to feed her only 1/4 of a cup of dry food a day and feed her a lot of canned. This really worked for her. I now feed mine Merricks Healthy Weight dry food which is grain free to everyone except Alani who is on a special urinary diet. Good luck.
