Kittens (0-6 Months):

Kitten is a period when your cat is growing quickly and is not sexually mature. The first period is the eye-opening practice for kittens after birth. It takes two-three weeks to open a kitten’s eyes and ears after birth and this is the point when a kitten’s physical and mental health starts growing. Kitten starts sights, smell, and sound like a human newborn baby. This is the time when a kitten’s personality development starts. Within a few weeks, the socialization skills start growing according to the different interactions, persons, objects, and exposures.

Within two-three months, the kitten starts to become more independent and gets curious about new things. Kitten leaves the mother and keen to explore new things just like the human infant. Despite not having its adult teeth, the kitten gets into a troubling behavior to chew the things that it should not. This period of six months comprises of fast growth and after the six months, its age is equal to a ten-year-old human child. Vaccinations are necessary to perform during the kitten period.

Kitten to Adult (06-Months to 03-Years):

As you know a six-month-old kitten is equal to a 10-year-old human child, it continues to explore its world as it converts into an adult. When your cat is one year old, it will be turned into its full size and its personality will be established according to its preferences and habits.

Note here that a one-year-old cat is typically equal to a 15-year old child, and a two-year-old adult cat is equal to a 24-year old person according to its physique. There is no need to perform vaccination when your cat is turned into an adult but you need to visit the veterinarian for normal check-ups to keep your cat healthy. Moreover, this period from 06-months to 03-years is a good time to form a baseline blood work performed to know your cat’s personality and values.

After 03-06 years your cat is not younger anymore. She is a full-fledged adult now. You don’t need to worry much about your cat’s health during this period but their health condition varies from cat to cat and some cats can get into chronic health issues and it will need good treatment.

Typically prime cats don’t face any chronic health issues but they need casual vet check-ups along with some vaccinations because in some cases they may concern some serious health issues.

Moreover, some joint support supplements are available to benefit your cat for its hips and knees working as they should. A prime cat with the age of 05-years is physiologically equal to a human of the age from 25-30 years.

 Prime to Mature (07-Years to 10-Years):

From seven to Ten years of age, your cat is mature but you cannot consider it a senior cat. Some veterinarians may consider mature cats as senior but we know that since cats typically live into their late teens, they are not considered yet senior cats.

During this middle age, you will have to ensure that your cat gets proper nutrition to avoid obesity. Dental disease, kidney issues, or heart murmur are the common health issues in this age and you need to ensure that your cat is not facing these issues. You also should be concerned about the physical performance of your cat that they are still able to jump on and off things easily.

Blood work through physical activities is necessary to keep the organs of your cat in good condition along with more routine check-ups to the veterinarian.


 Mature to Senior (11-Years to 14-Years):

This is the age when your cat can be considered a true senior citizen and it can get retirement. Joint issues along with physical performance and a clear decrease in organ functionality are the most common issues in this age. Owners of senior cats should be addressed to these problems. Blood work motoring and dietary changes should be performed at this age according to the recommendations of your veterinarian because senior cats require specific and different nutrition along with changes in the body.

At this age, some senior cats may show irritable behavior because joint pain or joint discomfort are the common issues. Quickly visit the veterinarian if you find any of the above-mentioned changes as they are the signs of something bad is going to happen with your beloved pet.

Senior to Super Senior (15-Years to 20-Years or Older):

Cats live a long time and the cat of 15-20 years old is comparable to a person at the age of mid-70s. A 20-years old cat would almost 100-years of age if it would be a person. Cats at the age of 15 are considered geriatric and must visit the veterinarian every six weeks. Special foods, supplements, and medications can be recommended to keep the body organs and systems working. Geriatric cats may face decreased visibility, hearing issues, and sleep disorders at this age.

Cognitive decline is another common issue in super senior cats as most humans might face in their 90s. Crying at night and urinating are the common examples of cognitive dysfunction. These geriatric ones need special attention.
