Cortisol and other hormones release a surge of energy in the form of glucose (sugar), which the body can use to fight or flee. That rush of glucose is no problem if your body's insulin response is working correctly.
Notice that the kittensâ ears are just beginning to unfold, though their eyes remain closed. Their sense of smell, hearing, and taste are slowly starting to develop. Tweed is only three days old. After almost a week, the kittens begin to wiggle around on their own a little bit and their eyes start to open.
Kittens eyes usually open 2 weeks after birth. If the mom has adequate milk and the family is indoors (WARM) they won't die. Kittens 4 weeks and under need to be kept warm! If the mom is not providing enough food for the kittens, you need to buy KMR and a bottle for kittens and feed them.
