Question: how many hours can a newborn kitten go without eating?
Answer: If you feed them every 2-3 hours through the day, you should be able to sleep yourself about 6-8 hours without feeding them. Make sure the bottle is tipped up so they are not swallowing air, and it is better to feed them with them in an upright position, not on their backs. The kittens should have a good suckle reflex.
