Hum if you just got them they are probably just really tired from the stress of the trip. I have two saharans right now, rico is really fat, he eats in the AM and is out until maybe 1 or 2 PM, then he sleeps and he might come out again at night but not for long. He's a bit lazy, the other is my new girl, she actually came and had a runny stool, so ASAP i took her to the vet. She has a possible bacterial infection, perscribed flagyl and is way better already. She ate however from day one. As long as they have no runny stools, or anything terribly out of the ordinary i wouldn't worry too much. Rico didn't eat for almost a week after i got him, the girl ate within one hour. It all depends. My girl also looks super skinny, she weighs in a 71 grams, and i just recieved her two days ago. Rico is weighing in at 128 grams, he's about 1 1/2 years old and still growing. Wild caughts don't really come with alot of weight and it might take a few weeks or a few monthes. Good luck and take them to a vet for a full checkup if you want to be sure.
I hope you have fun with your new additions, sorry for the long post...
