Your little group of kindles is a miracle in progress. At birth, kittens are entirely reliant on their mothers for food and warmth. Their tiny bodies can’t regulate temperature very well and they often crawl over each other in a pile of kitty warmth. Kittens’ eyes and ear canals are closed during their first few days of life, rendering them unable to see or hear one another. Newborn kittens spend their first weeks eating, sleeping and cuddling in order to survive. Source: thenest
