Russian Blue kittens are born with their eyes sealed shut and their ear canals closed, making them entirely dependent on their mother for warmth, nourishment, and stimulation. A healthy newborn Russian Blue typically weighs between 85 and 120 grams at birth, and each kitten should be gently weighed and checked for obvious abnormalities as soon as possible after delivery. The queen will normally chew through each umbilical cord and consume the placenta, but breeders and caregivers should verify that a placenta has been passed for every kitten born.
During these first hours, the kittens should begin nursing within one to two hours of birth. Colostrum, the first milk produced by the queen, is rich in maternal antibodies that provide passive immunity against common feline diseases. If a kitten is struggling to latch or appears significantly weaker than its littermates, it may need to be guided to the nipple or supplemented with a kitten milk replacer under veterinary guidance.
The nesting area should be kept quiet, dimly lit, and free from drafts. Russian Blues are a naturally cautious and sensitive breed, and the queen may become stressed if the environment is too chaotic. A clean whelping box lined with soft, washable bedding provides the ideal setting. Caregivers should observe from a respectful distance, intervening only when a kitten appears to be in distress or the queen is neglecting one of her young.
It is also wise to note the time of each birth and the order in which the kittens arrived. This early record-keeping helps identify any kitten that may fall behind in weight gain or development over the coming days. A kitchen scale accurate to one gram is an invaluable tool during this period.
