Neurological development of the kitten
The neurological development of a kitten can be followed depending on its motor development. In the beginning, the kitten crawls with the help of its front legs, but, little by little, the hind legs are reinforced and increase the movements of push.
eyes open between the sixth and twelfth day of life; the reflex that turns the head in response to auditory stimuli develops one or two days before. As they grow up, the kittens gradually know how to find their way back to their diaper: once they have their eyes open, they know how to use visual stimuli, whereas previously they only used olfactory stimuli.
Increased visual acuity
visual acuity and ability to see increased dramatically between the second and tenth week. For example, adult cats (just like dogs) react to the sight of the only silhouette of an animal of their species as if it were a real animal: they are apparently frightened and bristle (piloerection ) when shown for the first time
Five-week-old kittens do not respond at all, and six-week-old kittens react little, while at eight weeks they react like adults.
Kittens emit ultrasound perceptible to the mother. The smaller kittens are less active and if they are placed on a warm surface, they emit sounds of lower intensity and frequency; this calming effect of the thermal stimulus disappears after the first week of life
A kitten left alone cries emitting about four cries per minute at three weeks of life; bigger, he cries less. The response to physical restraint does not change as it grows (five cries per minute)
