Are you curious about the age of a lovable kitten that has caught your eye, or have you recently welcomed a new furry friend into your home and want to better understand their developmental stage? Discerning a kitten’s age is essential to provide them with the proper care, nutrition, and socialization. Here are four ways to determine how old your kitten is.

1. Size and Weight

One of the easiest ways to assess a kitten’s age is by observing their size and weight. Newborn kittens are tiny and usually weigh between 3-5 ounces. From being under one-week-old, kittens start gaining weight rapidly. They double their weight by 1-2 weeks and continue to grow robustly until about three months of age. After that, growth slows down but continues gradually until they reach adulthood at around nine months.

2. Eyes and Ears

Observing the eyes is another helpful method in estimating the age of a kitten. Newborn kittens are born with closed eyes that will gradually open within the first 7-10 days after birth. When first opened, kitten eyes reveal a deep blue color which begins changing to their actual hue at around seven weeks.

Similar to the eyes, kittens are born with sealed ears, which open within the first two weeks after birth. By four weeks old, their ears should stand upright without any difficulty.

3. Physical Development

As kittens mature, their physical development starts showing various milestones that can help you gauge their age. Kittens will begin crawling at 1-2 weeks old but don’t become fully mobile until 3-4 weeks of age when they start walking confidently and exploring their environment more efficiently.

At around 5-6 weeks, kittens practice social skills such as play-fighting and grooming themselves, demonstrating their independence from their mother. By eight weeks of age, most kittens exhibit signs of improved coordination by running, climbing, and playing with their siblings.

4. Teeth

Lastly, a kitten’s teeth can provide valuable information about their age. Kittens, like humans, develop two sets: the baby or milk teeth and adult or permanent teeth.

At 2-3 weeks of age, their baby teeth start emerging—first incisors, followed by canines, and then premolars. By six weeks old, they should have all their 26 baby teeth. Starting from 12-16 weeks

onwards, kittens gradually lose their baby teeth, which will be replaced by 30 adult teeth (12 incisors, four canines, ten premolars, and four molars).

In conclusion, determining a kitten’s age is crucial for providing them with proper care and support. If you’re ever unsure about your kitten’s age or require further advice on raising them healthily and happily, consult your trusted veterinarian.
