When you think of cat life stages, you might think that they consist of kittenhood, adulthood and senior age. You might also think that once a cat reaches adulthood, there isn't much difference between cat care in adults and younger cats. If that's the case, you'll be surprised to learn that, according to International CatCare, cats go through six distinct life stages, all of which have their own care and feeding requirements. Keep reading to learn which of the cat life stages your cat falls into, and how you can provide your cat with the best care and nutrition for their age. Please keep in mind that some cats mature quicker than others, so it is important to check with your vet to make sure they are getting the right nutrition as they grow.

Kitten Stage (Zero to Six Months)

A kitten is the cat equivalent of a human infant. Kittens grow and develop much faster than human beings, however. During their first six months of life, a kitten will transition fairly rapidly through stages that are similar to that of a human child — from newborn to toddler to preschooler to big kid.

  • Appearance: Kittens are easy to spot. They look exactly like what they are: tiny baby cats. They start out with shortened ears and a tail that grows to be more proportionate with their bodies as they mature.
  • Behavior: Kittens are continually learning and discovering the world around them. In the beginning, they're helpless, relying completely on their mother and their human helpers for every aspect of their care and protection. As they grow and develop the skills to explore their environment, they are driven by curiosity. Between that, a lack of fear and an abundance of energy, kittens can be rambunctious and prone to mischief.
  • Care and training: Typically, by the time you adopt a kitten, they'll be fully weaned from their mother and eating solid food. They'll also be mobile and quite capable of climbing, jumping, playing and getting into things, and will have yet to learn that some objects and activities are not good for them. Kittens require a lot of patience and supervision. Before getting a kitten, you'll need to kitten-proof your home by blocking off vents and other dangerous places that are small enough to climb or crawl into, putting cords and electrical cables out of reach, moving house plants where they can't get to them, and securing window screens and doggy doors to prevent them from escaping.

In general, kittens should have received their first vaccinations by the time they're old enough to be adopted, but they may be ready for a booster shot around four months of age. Consult your veterinarian to discuss the best time to spay or neuter your kitten. Your veterinarian can discuss these options, as well as their vaccination schedule when you take them for their first wellness exam. Your vet can also help determine the best methods for controlling fleas and other parasites.

Your new kitten will need to be litter box trained, but the concept is both instinctive and something they learn from their mother, so training is mostly a matter of getting them used to the box and gently reminding them to go there by placing them in it when it looks like they need to go. Otherwise, kitten training mainly focuses on socializing them to people and other animals, and establishing house rules and behavioral boundaries.

  • Nutritional needs: Growing kittens need an appropriate amount of protein to support growth and development, without which their growth may be stunted or they may develop health problems. Kittens should be fed a high-quality kitten food that's specially formulated to support their rapidly growing bodies. Kittens can also be fed smaller meals more frequently throughout the day than you would feed an adult cat to keep up with their rapid metabolism. Just remember to adjust their feeding schedule as they grow to avoid any issues with becoming overweight.

Junior Cat Stage (Six Months to Two Years)

The junior life stage is equivalent to human adolescence. During this stage, a cat loses their babyish appearance as they reach physical and sexual maturity. They also outgrows their kitten personality and settles into their true temperament.

  • Appearance: As they transition out of the kitten life stage, a junior cat sometimes goes through a bit of an awkward stage as they experience growth spurts that leave them looking long and lanky.
  • Behavior: This is a transitional cat life stage, during which they should start settling down and growing out of rambunctious kitten behavior and learning to behave more like an adult cat. By the time they reach about 18 months of age, they'll likely be much calmer.
  • Care and training: The vaccination schedule established with your vet should be continued. As your kitty outgrows their kitten behavior and settles into adulthood, they'll need less supervision. Training at this stage is generally about reinforcing rules and boundaries and continued socialization.
  • Nutritional needs: At one year of age, it will be time to transition from kitten food to adult cat food. Whether to start feeding adult kibble or canned (wet) food is really a matter of personal preference. Either way, a standard adult formula should meet all their nutritional needs. It's not uncommon for cats at this stage to put on extra weight after being spayed or neutered, so they'll need to be monitored to make sure they're not being overfed. Your veterinarian should walk you through what to expect after the procedure if you choose to have them neutered.

Prime Cat Stage (Three to Six Years)

At this stage, your cat is in the prime of their life — about the equivalent of a human in their twenties and thirties.

  • Appearance: A cat at this stage should be at the peak of health and physical fitness. They're as long and tall as they're going to get, and should be filled out but not overweight, with a sleek body and a healthy, shiny coat.
  • Behavior: By now your kitty should be fully settled into their natural adult temperament, which varies from cat to cat. Barring the development of any behavior-altering illnesses or disorders, the personality your cat displays now is the personality they'll have for the rest of their life. They should be active and playful, with their routines and  territory well-established.
  • Care and training: ;Although in peak health, caring for adult cats in their prime should still involve regular health checkups. By this point, your cat should be fully trained, although they may test boundaries from time to time and need to be gently reminded of the rules. If a cat hasn't outgrown problematic behavior at this stage, you may need to consult a professional trainer for help to correct the behavior, and check with your vet to make sure the undesirable behavior doesn't have an underlying medical cause. If you choose to adopt an adult cat, you can still train them. Cats, unlike dogs, are more independent in nature, so it may seem difficult to train your cat, but it's definitely possible so just be patient with them.
  • Nutritional needs: At one year of age, it will be time to transition from kitten food to adult cat food. Whether to start feeding her adult kibble or canned (wet) food is really a matter of personal preference. Either way, a standard adult formula should meet all her nutritional needs. Energy needs decrease after neutering, so it’s important to make sure that your cat is not being overfed.  Your veterinarian should walk you through what to expect after the procedure if you choose to have her neutered.

Mature Cat Stage (Seven to Ten Years)

A mature cat is about the equivalent of a middle-aged human in his or their forties or fifties.

  • Appearance: Outwardly, your mature cat might appear no different than a cat in their prime, especially if they remain active. Cats in this life stage are more prone to weight gain and obesity, however, so it's not unusual for them to put on weight, and their coat might begin to lose some of its sheen.
  • Behavior: Although some cats remain active and playful well into their senior years, it's not unusual for a mature cat to slow down and become more sedentary.
  • Care and training: As with a younger adult cat, you may need to reinforce training from time to time, but not often. Caring for cats at this mature stage is more involved, as they are not only at higher risk of obesity and obesity-related health problems, such as diabetes and high blood pressure, but their risk of cancer and other illnesses like kidney or thyroid disease. They should get regular checkups with the vet and also be closely monitored at home for signs of illness, such as weight loss, unusual vomiting or diarrhea.
  • Nutritional needs: Mature cats require an array of nutrients to keep their body in tip-top shape. This includes vitamins C and E to boost her immune system. If she's prone to packing a few extra pounds, you may need to adjust her food to accommodate her activity level or choose a food designed for inactive cats.

Senior and Geriatric Cat Stage (Eleven Years and Older)

Cats in their advanced years are separated into two cat life stages. Those from eleven to fourteen years of age are considered senior cats, which is about the equivalent of a human in his sixties and seventies. Ages of fifteen years of age and older are considered geriatric cats.

  • Appearance: Senior cats are likely to show signs of aging, such as developing more white in their fur and losing luster in their coats. These features may grow more pronounced as they continue to age.
  • Behavior: Cats in these advanced cat life stages are at increased risk to the conditions and illnesses mentioned in the mature stage, and are also prone to mobility issues caused by arthritis or other joint problems. This may cause your cat to slow down considerably, and it may also cause her to stop using the litter box, especially if it has high walls that are hard to climb over or is in a hard-to-reach location. 
  • Care and training: Caring for senior and geriatric cats can be a challenge. Your elderly cat should continue to receive regular health checkups and be closely monitored for health problems. At this stage, the main focus is to keep her comfortable and as healthy as possible for as long as possible. Be sure her litter box is easy for her to get in and out of and that her food and water are easy to get to. Many aging cats go on to live long lives in their senior life stage and can be quite active, but their playtime may just not last as long. The good news is that she may be more willing to cuddle, strengthening your bond even further.
  • Nutritional needs: If she develops health problems, your vet may put your kitty on therapeutic cat food as part of her management plan. Otherwise, a quality senior cat food formula should sufficiently meet all her nutritional needs. If your cat isn't drinking enough water, your vet may recommend switching to moist cat food in order to help her stay hydrated.

As you can see, cats go through a number of changes throughout their lives. By knowing the current life stage of your cat, you'll be able to tailor them care accordingly to help provide them with optimal health, nutrition and quality of life so you two can experience the joys of life together.
