Kitten Development: A Week-by-Week Guide:

The initial six weeks of a kitten’s life are vital for their development, marked by rapid growth and change. After leaving the womb, a kitten will require warmth, proper nutrition, and protection from infections and parasites like fleas. During this phase, their growth is unparalleled and observing their weekly progress is truly remarkable. Begin by understanding their development in the first week and continue tracking their progress from there.

Week 1: Tiny Food Processing Factories:

At birth, a kitten is tiny, weighing just a few ounces and fitting comfortably in the palm of your hand. Its umbilical cord will detach within the first two or three days, but its eyes and ear canals will still be closed.

During this vulnerable stage, kittens are completely dependent on their mother. She instinctively meets their needs by feeding them, keeping them warm, and bathing them with her rough tongue. This grooming not only helps with digestion but also stimulates their ability to urinate and defecate. Mother cats are highly protective and will relocate their kittens if humans interfere too much with their nest.

If the mother cat has been vaccinated or has natural immunity, her kittens will gain this immunity through her colostrum during the first 24 to 48 hours, which will protect them until they are old enough for their own vaccinations.

At birth, kittens typically weigh around 3.5 ounces and may double their weight by the end of their first week. It’s important to weigh them regularly to ensure they are getting enough nutrition. At this stage, their primary activities are nursing, sleeping, and eliminating waste, with minimal social interaction except for competing to nurse from their preferred nipple, where they also knead with their tiny paws.

A general guideline for feeding young kittens is to provide eight cc (or ml) of formula per ounce of body weight each day. You should gradually increase the formula amount for each feeding while reducing the number of feedings over time. Note that one cubic centimeter (cc) is equivalent to one milliliter (ml), and one ounce is equal to 30 cc or ml.

Week 2: Growing and Developing:

Your kitten continues to grow rapidly, gaining around 10 grams per day. To help replace the nutrients lost through nursing, the mother cat should be given high-quality canned kitten food. Eventually, the kittens will also be introduced to this food.

The kitten’s eyes will begin to open and should be fully open by nine to 14 days old. Initially, all kittens’ eyes are blue and will stay that way for several weeks. Their vision will be blurry at first, and their pupils won’t adjust to light changes well, so they should be kept away from bright lights.

Week 3: Awareness is Growing:

The ear canals will be fully open, though their hearing is still maturing. Kittens may react to loud noises by starting or becoming startled. By this stage, their ears might be standing upright.

Their eye color may begin to shift from the universal blue to their adult shade. Their sense of smell will be well-developed. Kittens can now eliminate on their own as their digestive system continues to mature. The mother cat will keep cleaning them until they acquire grooming skills.

It’s not unusual for kittens to begin purring at this early stage. Their baby teeth will start to emerge, and the mother cat will begin considering the weaning process.

Week 4: Standing and Wobbling:

Between the third and fourth weeks, kittens will begin to stand and attempt to walk, though their initial steps will be quite unsteady. Their bodies are not yet proportional to their adult size— their tails are short and “stick-like,” and their heads appear much larger compared to their bodies and legs. This imbalance will gradually correct as they gain stability and start moving more confidently.

As they explore their surroundings, don’t be surprised if kittens start escaping from their nesting area. They will also start interacting more with their littermates, forming “alliances” that may or may not be based on gender.

Kittens will keep nursing frequently. It’s crucial to provide the mother with high-quality food while she is still nursing her kittens.

Week 5: Beginning the Weaning Process:

At this stage, kittens will begin to walk around freely and start playing with their siblings. They will begin to develop a sense of independence but may still stay close to their mother and littermates. This is an excellent time for them to start socializing with humans.

Kittens can be introduced to canned food now. Choose a high-quality kitten food with a named meat source, such as chicken, as the first ingredient. Ideally, use the same food that is provided to the mother cat, as the kittens will adapt quickly to it. Serve the food on a shallow plate and expect their initial attempts to be quite messy.

Even though the mother cat will begin the weaning process, the kittens will still need to nurse to fulfill their suckling instincts until they are about eight to ten weeks old, by which time the mother will have gradually weaned them.

Kittens can also start learning about litter box use at this stage. They require a smaller, easily accessible box with just an inch or two of litter. A shallow plastic storage container or a shoebox lid can be suitable starting options. Just as human babies explore by tasting everything, kittens will investigate their environment, so it’s important to prevent them from ingesting harmful substances. Opt for a natural litter, like those made from corn cobs, paper, or wood chips, and avoid clumping clay.

Week 6: Active Socialization:

Socialization skills are in full development, and these energetic kittens are growing quickly into adult cats. They can run, pounce, and leap with enthusiasm, providing endless entertainment for themselves and their human companions. They can also fall asleep instantly due to their active play, so be mindful not to let them become overly tired.

Kittens will mimic their mother cat’s behavior in interacting with humans. If she has a positive relationship with people, her kittens will likely follow suit. However, if they are not used to being handled by six weeks of age, it may be challenging to socialize them later, and they might never become as affectionate or comfortable with humans.
