Guide to Determining a kittens age

Newborn Kittens:

When kittens are born, they are completely dependent on their mother. They are born with closed eyes and folded ears, unable to stand, regulate their body temperature, or feed independently.

Newborn kittens, just hours old, have distinct characteristics that differentiate them from older kittens. Understanding these features can help caregivers provide the appropriate care needed during this critical stage of development. Newborns still have their umbilical cord attached, which is usually moist and will dry up and fall off within a few days. The ears are also closed and folded flat against their heads. The fur is very fine and may appear slightly damp at birth. It will start to fluff up as the kitten dries. The coat color may not be fully developed, and patterns may not be clearly visible yet. Their skin is thin and delicate, and the kittens may appear somewhat wrinkled due to their lack of fat. The nose and mouth are proportionately larger compared to the rest of their face, and the nose is typically pink and moist.

First Week:

During their first week of life, kittens remain blind and deaf, relying entirely on their mother or caregiver. They weigh between 3-5 ounces and require round-the-clock care, including feeding every two hours.

Kittens snuggle together for warmth.

Eyes turn blue, a color that will change over the next few weeks as their true eye color develops.

Kittens continue to grow quickly. By the end of the second week, their ears are nearly fully uncurled, and they begin to crawl. They are still completely dependent on their caregiver for food and waste elimination.

Kittens start exploring away from their mother, though they are still unsteady on their feet.

By two weeks, kittens become more aware of their surroundings and begin interacting with their littermates. They start to develop their sense of smell, which may lead them to hiss at unfamiliar scents or sounds. Kittens also begin kneading, although their claws cannot retract yet.

In the third week, you can identify the kittens' genders. Their teeth begin to emerge, and they start walking more confidently. This is the time to introduce a litter box and wet food. Kittens become more playful and mobile, spending time engaging with their littermates.

By four weeks, kittens are stable on their feet and actively play with each other, toys, and people. They resemble smaller versions of adult cats and begin showing interest in exploring their environment. This is an ideal time to begin socializing them.

At forty days, kittens exhibit instinctual behaviors like stalking, hiding, pouncing, and digging, crucial for their development.

By six weeks, kittens are adept at self-grooming and grooming each other, strengthening sibling bonds. Introducing grooming during interactions helps simulate maternal care.

At forty-five days, kittens begin using scratching posts and learn basic routines like claw trimming, preparing them for life in their new homes.
