How lucky you are! You have got a super precious gift in life, which is your cutie pet cat.
Cats make our days, stand beside us as a friend through thick and thin, give us consolation during our worst moments…
So, when are cats full grown?
Undoubtedly, for some people, these creatures are more of a cutie little princess than a mere favorite pet. And we all know it, our tiny furry friend will soon turn into a mature adult cat sooner or later. The moment this happens should be well celebrated.

Age as a powerful indicator

Trees shed out his old leaves to show that he is ready for a new “shirt”, flowers send out special fragrances to inform they are about to boom. So which signs will play the role of an “informer” when a cat reaches his maturity?
The answer is undoubtedly age. But, how old are cats when they are full grown?
No kittens resemble one another when it comes to growth rates as different kittens are treated to distinct breeding conditions. Therefore, there is no exact weight or length measurement to base on.
Rather, this is judged by when your kitten is likely to hit certain important life milestones. These milestones can be things like being able to “give birth”, eat independently, being fully weaned, reaching social maturity.
Remember that these are just basic benchmarks and the age at which felines achieve them differs.

Why? You might wonder

At six months old, kittens are half and three quarters to the adult size. Once a kitten celebrated his one-year-old birthday, he is already considered an adult cat. But probably he is not yet grown to his full potential.
Typically, the average length and weight bear the most resemblance to that of the mature period when he is around 9 to 12 months of age.
Throughout the 18-month period ahead, he will happily enjoy living the life of a real adult, with his temperament getting calmer and less hyperactive than as a naughty little baby. Growth rate at this time begins to get slower and slower.
This stage is equivalent to the teenage years of human beings. Thus, body changes and behavior formation can be obvious. The fully-grown cat may get overweight when he fails to stick to a proper diet and appears lazy in “exercising” to burn the extra calories.

Sexual Maturity

In its ladder of development, a cat is like a climber that has to conquer every single step little by little. In fact, it is sexual maturity that we can determine when cats are considered full grown. And it is the pet owners who suffer most from insomnia because of the problems they may encounter with their baby cats.
During this period, which commonly happens between 5-9 months, spaying and neutering are inevitable tasks that hold the key to the overall well-being of your feline. It’s worth noticing that at this point, your pet cat has the ability to reproduce and is more drawn to the attraction from her male counterpart.
Worried that your little furry friend may get pregnant? Generally afraid that reproduction may inflict bad influences on your cat’s still-maturing body? Then, you should try to separate her from the male cats and get her a check-up if you suspect she may have been in pregnancy.

Pregnant cat? How to know

Cat owners may not immediately figure out whether their cat pets are pregnant or not till nesting begins. So, get as prepared as possible for your cat as she may be going to make kittens if she develops such “symptoms.”

  • Her nipples get enlarged after 2 weeks
  • In the second three weeks, she becomes less energetic and shows a swollen belly
  • In the final stage from week 7 to 10, signs are more noticeable as the “future mommy cat” stays away from humans to find her nesting place.

Spay and Neuter, yes or no?

The answer had better be yes.
Spaying for “female feline” helps avoid unplanned or unwanted pregnancies during the puberty years. The procedure may appear daunting to some cat owners as they are afraid their nearly-mature cats, which are still kitten-like at heart, might get hurt.
You may be worried, too, right? But calm yourself down and consult your Vet to decide upon the most proper time to operate this procedure on your cat. Health-wise, this should be done before cats are fully grown as for male cats, getting neutered at an early age prevents spaying problems from arising in late years.

Social maturity

Are you feeling a bit unpleasant when hearing these 2 words? If yes, you are not alone because many pet owners dislike this stage of growth in their baby cat.
You may ask why. Getting mature socially is one of the signs to show that your cat is heading towards a new chapter of life, which is when it becomes an adult. Sounds like an important turning point for cats, but for human beings, this is when they have to endure sudden changes in the cat’s behavior and temperament. Now gone, the cuteness and affectionate side. Instead, Mr. Cat acts as a more mature person, getting settled down and mellow. Even some clinging can be witnessed some time, which is quite strangely annoying.
However, if you get your cat spayed and neutered at a propitious time, he/she will remain kitten-like forever, being playful and craving for attention into old age.

Big guys make an exception

I have a confession to make. Domestic cats of all genre may not always seem so adorable as to easily fall in love at first sight with. In reality, some are quite robust in size and body because certain creatures don’t reach cat-hood until they are 2-4 years old. The list that these pets are in is called “The biggest domestic cat ever” or “Typical late boomers domestic cat”.
Let’s see what the list unfolds.

When is Maine Coon fully grown?

Maine Coon – the name attached to an honorable World record for the largest breed of cat ever. Owners of Maine Coon will be proud as he is superior to his contemporaries of other breeds in terms of intelligence and athleticism. Up till now, no other cats seem to successfully steal this title. As a result, the big guy Maine Coon may experience up to 4 to 5 years to finally reach its full-grown state:

  • Length: up to 48 inches
  • Height: 8-16 inches
  • Weight: up to 25 pounds, and to 35 pounds for a giant one

When is Bengal cat fully grown?

As its name reveals, Bengal cat resembles a “small leopard”, with black crossings all over its fur. When reaching adulthood, Mr. Bengal will be slightly heavier than a Miss. Bengal.

  • Length: 13-16 inches
  • Height: up to 11 inches
  • Weight: 10-22 pounds

The journey to cat-hood may take somewhere between 1 and 2 years.

When is Savannah cat fully grown?

Savannah is a hybrid breed, often described as a “small cheetah”. But this “cheetah” is irresistibly adorable, loves following its owner around like a little puppy. This cat has to live from 2-3 years as junior to eventually be recognized as a mature guy.

  • Length: 15-26 inches
  • Height: 9-11 inches
  • Weight: 8 to 20 pounds

When is British Shorthair cat fully grown?

Disheartening as it seems, the total time required for this cat to reach full adult size is from 3 to 5 years
I know, waiting has never been a pleasant experience. Yet, I still recommend adding this cat as a member of your cozy home because the final result makes waiting worthwhile and rewarding.

  • Length: 16-22 inches
  • Height: 14-20 inches
  • Weight: 7-18 pounds

Special things about this breed that prospective owners have to note down is that it is clumsy and dislikes being with humans. Despite that, British Shorthair is well-dignified and often acts as a “potential movie star” in films and commercials.
In short, the more massive the cat, the more time it takes to be fully grown.

Which one reaches cat-hoot faster, outdoor cat or indoor cat?

Come on, venture a guess on this question.
Surprisingly, the answer is the former since cats that live outdoor age twice more quickly than those kept and raised inside. An outdoor cat is similar to an active, sociable person, while the other is more or less inactive and passive.

Make a what-to-do list

What is considered necessary for the growth of a child in adolescence?
Logical diet scheme? Proper physical exercises? Social interactions? Life-skill enhancement?… List as many as you please. And because a kitten is no more than a growing human body, such aforementioned aspects are major constituents of its prospective growth too.
Thus, as a pet owner, you should…

  • Treat your feline to a diversified eating menu, at least on a weekly basis, to make sure its nutritional needs are fulfilled. Around 12 months, changes from kitten food to cat food is required.
  • Monitor your cat’s intake of food in case it eats more or less than the standard amount suggested by your personal vets. Bear in mind that the cat will eat less after passing his first year of age.
  • Be sensitive to notice a weight increase in your cat and cut down on her daily consumption of kibble. Overweight may affect her life health and “longevity”.
  • Don’t leave your cat alone. Instead, create social bonds by interacting with it regularly.
  • Invest in the entertainment of your cat, especially for those playful and hyperactive guys

Final words

Different felines are different stories, so view the above information as a source of reference to judge when your treasure kitty becomes an adult cat. If anything goes wrong during its puberty years, it is advisable to see a vet and have the problems solved.
“The smallest feline is a masterpiece,” – says Leonardo Da Vinci. So it should be human nature to treat every cat as a sweet, trustworthy friend.
