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.
Determine the age of the kitten to see if he or she needs to be bottle-fed or can start immediately on soft food: 1  Eyes closed, ears folded over - kitten is 1 - 14 days old. 2  Eyes are open, kitten moves around but is wobbly - 2 - 3 weeks old.  Eyes are open, ears up, can walk around - 3 - 4 weeks old.
