The Growth Stages of a Cat

Cats experience different growth stages throughout their early years. From the second they’re born to their first rare years of life, there’s much growing to look forward to. Sympathetic, these stages will give your vision into when your cat’s strength reaches adulthood.

Kitten Stage (0-6 Months)
A cat finishes an intense date of development and growth throughout the first six months of life. Kittens experience tremendous mental and bodily development at this time. Conferring to the type, your kitten could consider anything from 3 to 6 pounds by the instant they are 6 months old and have classically tripled in size by the time they are eight weeks old.

Adolescent Stage (6-12 Months)
Cats grow once they reach the teenage stage, which starts to slow down around six months. They may begin to gain bulk around this phase, and they may start being more fun and energetic. Even though their growth will not be as rapid as during the kitten period, they continue to observe specific physical changes. By the finish of this stage, most cats will be approximately eighty percent of their mature size.

Young Adult Stage (1-2 Years)
At around 1 year old, cats will start to look more like adult cats, but they still develop in certain areas. Larger breeds may still be growing, while smaller breeds are generally close to full size by this point. Muscle development and the final shape of their body will become more apparent during this stage. Some cats, significantly larger breeds like Maine Coons, can continue to grow and develop for another year or two.

Full Maturity (2-3 Years)
Most cats stop growing by the time they reach 2 years old. Their height, weight, and body length will be fully developed. However, large cat breeds like the Maine Coon, Savannah, and Ragdoll may take longer to reach their full size. These cats can fully mature up to 3 years; some might still gain muscle mass or fill out after their second birthday.

When is a Cat Fully Grown?

Most cats seem “complete” in size by the age of 1 to 2 years, with few exceptions for a large breed that may continue growing until around 3 years. So, when is a cat fully grown? Let‘s examine some indicators.

Physical development: Some changes will occur in the body shape of your cat as they grow older. In general, a kitten has a rounder kitten‘s face, whereas a more mature cat has a longer characteristic face typically consisting of a thinner neck. Specific alterations in the coat’s texture or thickness may also appear in the later stages of development, as they have specific reasons.

Body weight: The average weight for a cat of a specific breed will reach its maximum weight for most cats, which differs according to the breed of the cat. Typically, an adult cat weighs anywhere between eight to twelve pounds. Some breeds may weigh more but it is recommended that a cat of any breed does not gain more than that. A pet cat that has crossed its one-year mark and is still continuing to grow weight suggests that the development of that cat has not been completed yet.

Temperament: You will witness drastic behavior changes as the cat grows. Kittens are considered hyper and playful in nature which generally changes as they become adult cats because the activity is known to settle. If your feline friend has grown out of their mischievous antics and has started to become passive, it can be said that your feline has aged quite a lot.

Size and Length: Cats eighteen months of age are generally seen as having reached full height, length, and even weight, but certain types persist in getting bigger until two years. So, if your cat is significant, they are still growing in muscle bulk and bone volume and may also be regarded as not fully matured yet.

Factors That Influence Cat Growth

Several factors influence the rate at which a cat grows and when they reach full size. These include genetics, breed, nutrition, and overall health. Here’s how each factor can play a role:

  1. Breed
    One of the vital elements that help in knowing a cat’s age is its type. The smaller breeds, which include Siamese or Singapura, will be full-grown at around 1 year old. On the other hand, there are larger breeds, such as the Maine Coon and Ragdoll, that will take time to attain their maximum size as adults. Certain suggested breeds may continue growing even until the age of three.

  2. Genetics
    Like humans, genetics is vital to a cat’s growth and size. Cats from larger parents will often be larger themselves. Remember that the size of a cat’s mother and father can give you a good idea of how big they’ll grow.

How to Track Your Cat’s Growth

If you’ve been waiting to learn how old your kitten should be before considering him or her as an adult, below are some valuable suggestions on how to follow their development:

Weigh Your Cat: A pet or home scale can record your cat’s weight and growth. It’s generally a more accurate picture of their developmental progression.
Measure Their Body Length: You can measure your cat starting at their nose tip and going down to the end of the tail to get their body length. They do reach a certain height and growth in that aspect comes to a standstill, but it’s possible for their general length to alter during their first 12 months.
Notice Changes In Their Activity Level: Another aspect of growing up that is very obvious is the dramatic change in how active a cat was when it was young and vice versa for older cats. If there is any change in their energy level and they appear calm, then it is likely that they are transitioning towards adulthood.

What You Can Do to Help Your Cat Reach Full Size

  • Adequately age and breed-specific diets to be fed regularly, and any unfair, extra or too little should be avoided.
