Kitten Age Chart
The kitten age chart serves as a comprehensive reference tool for cat owners, allowing them to track and estimate their kitten’s age based on key developmental milestones. By observing factors such as tooth development, weight gain, eye opening, and behavioral changes, the kitten age chart provides valuable insights into the growth and maturation of kittens. This visual aid, often presented in tabular format, aids in understanding and monitoring the progression from newborns to fully mature cats, emphasizing the importance of proper care and attention at each stage of development.
| Age Range | Tooth Development | Weight | Eye Opening | Behavioral Milestones |
| Newborn | No teeth | 3-4 ounces | Closed | Crawling on belly, reliant on mother |
| 1-2 weeks | Baby teeth emerging | 140-210 grams | Starting to open | Reacting to touch and sound |
| 3-4 weeks | Full set of baby teeth | 300-450 grams | Fully open | Beginning to walk, exploring |
| 5-6 weeks | Growing adult teeth | 600-900 grams | Fully open | Playing, socializing with littermates |
| 7-8 weeks | Adult teeth developing | 900 grams 1.3 kg | Fully open | Increased independence, weaning |
| 2-3 months | Adult teeth fully formed | 1.3 kg 2 kg | Fully open | Exploring, playing, socializing |
| 4-6 months | Adult teeth fully erupted | 2 kg 3 kg | Fully open | Developing hunting instincts |
| 7-12 months | Adult teeth fully developed | 3 kg 4 kg | Fully open | Maturing into adult behaviors |
How to Tell a Kitten’s Age by Physical Development
Determining a kitten’s age based on physical development is a fundamental aspect of feline care. Here are the key indicators to look for:
1. Look at their teeth or lack of teeth
A kitten’s dental development can provide valuable insights into their age. Newborn kittens are typically toothless, with their baby teeth starting to emerge around 2-4 weeks of age. By 6-8 weeks, they should have a full set of baby teeth.
2. Check your kitten’s weight
Weight can be a useful indicator of a kitten’s age. Newborn kittens weigh around 3-4 ounces at birth and gain approximately 0.5 to 1 ounce per day. By 8 weeks, a healthy kitten should weigh around 2 pounds.
3. Are their eyes open
Kittens are born with closed eyes, which typically start to open around 7-10 days after birth. The rate of eye opening can vary slightly among kittens but should be fully open by 2 weeks of age.
4. Do they walk around or play
The development of motor skills can also provide clues about a kitten’s age. Newborn kittens are not able to walk or play and are entirely dependent on their mother for care. Around 3 weeks of age, they start to explore their surroundings and engage in playful behavior.

How much weight should my kitten gain each week?
Weight gain is a crucial aspect of a kitten’s development, indicating their overall health and growth rate. Here’s a general guideline for how much weight kittens should gain each week:
| Age Range | Average Weight Gain per Week |
| Birth to 1 week | 10-15 grams |
| 1 to 2 weeks | 20-30 grams |
| 2 to 4 weeks | 50-100 grams |
| 4 to 8 weeks | 100 grams or more |
Monitoring Weight: It’s essential to monitor your kitten’s weight regularly during the first few weeks of life. Weight gain within these ranges indicates healthy growth and development. However, consult your veterinarian if you notice significant deviations or concerns about your kitten’s weight.
Factors Affecting Weight Gain: Keep in mind that individual factors such as breed, genetics, and feeding practices can influence a kitten’s weight gain. Ensure a balanced diet and appropriate feeding schedule to support optimal growth.
How Much Should I Feed My Kitten?
Feeding your kitten the right amount and type of food is essential for their overall health and well-being. Here are some additional tips and considerations:
Kitten Food Types
- Wet Food: Provides hydration and nutrient-rich diet.
- Dry Food: Promotes dental health and convenience.
- Combination: Mixing wet and dry food for balanced nutrition.
Feeding Schedule
- Age-Appropriate Portions: Follow guidelines on kitten food packaging.
- Multiple Small Meals: Offer frequent, small meals throughout the day.
- Avoid Overfeeding: Monitor portion sizes to prevent obesity.
Nutritional Requirements
- Protein: Essential for growth and muscle development.
- Fat: Energy source and support for coat and skin health.
- Vitamins and Minerals: Ensure balanced nutrition for overall well-being.
Transitioning to Adult Food
- Gradual Transition: Introduce adult food slowly over several days.
- Monitor Digestion: Watch for any digestive issues during the transition.
- Consult Veterinarian: Seek guidance on timing and method of transition.
What age a kitten is no longer a kitten?
Determining when a kitten transitions into adulthood can vary based on factors such as breed, size, and overall development. However, a common benchmark for when a kitten is no longer considered a kitten is around 1 year of age. Here are some additional insights and considerations:
Adolescence and Young Adulthood
1-2 Years: During this stage, cats are in their adolescent to young adult phase. They may still exhibit playful behavior but are also developing more mature habits and behaviors.
Physical Maturity: While kittens reach their full size by around 1 year, they continue to fill out and develop muscle mass during their second year.
Behavioral Changes: Cats may become more independent and less hyperactive compared to their kittenhood but can still enjoy interactive play and socialization.
Adulthood and Senior Years
3-6 Years: Cats are considered adults during this stage, with a settled temperament and established routines. They are typically healthy and active.
7+ Years: As cats enter their senior years, they may experience age-related changes such as decreased activity, changes in appetite, and potential health issues. Regular veterinary check-ups become even more crucial during this stage.
Lifespan Variability
Breed Influence: Some breeds, such as larger breeds like Maine Coons, may take longer to reach full maturity, with adolescence extending beyond 1 year.
Health Factors: Individual health and genetics can also impact the age at which a kitten transitions into adulthood and later stages of life.
Quality of Life: Providing proper care, nutrition, and veterinary attention can contribute to a longer and healthier lifespan for your cat.
Lifelong Care
Nutritional Needs: Adjusting diet based on life stage and health considerations.
Physical Activity: Encouraging exercise and mental stimulation throughout life.
Regular Vet Visits: Monitoring health and addressing any age-related issues promptly.
Understanding the various life stages of cats beyond kittenhood allows for proactive care and ensures a fulfilling and healthy life for your feline companion.
Conclusion: Kitten Age Chart
