No, I do not think it is safe for you to take them on a holiday because the kittens are only a week old, and they aren't old enough to do hardly anything, much less take a trip/holiday very well. Since it isn't safe, you should probably find someone to feed your mother cat, and check on them every so often to make sure they're okay, but you definitely shouldn't take them on a holiday/trip.
