umans, on average, tend to stop growing between the ages of 18 to 24-years-old, but when do cats stop growing? When are cats considered fully grown and become an adult cat? There are many questions that surround this topic, which we aim to answer for you. Knowing the answer to “when do cats stop growing and when are cats fully grown” will help you track the growth of your feline friend.


When Do Cats Stop Growing?

The average feline will grow from being a kitten to a full adult by the time they are around 1-years-old. This growth, however, is rendered by a couple of different growing aspects that attribute to their full growth into reaching adulthood.

1. The Breed

The Breed

The breed of a cat has a lot to do with when they are considered fully grown into adulthood. For example, the Manx, which is an incredibly old and ancient breed of cat, is not considered to be a fully grown adult from a kitten until they are at least 5-years-old on average.

Chartreux kittens are also a breed of cat that does not reach adulthood until years later. On average, a Chartreux kitten is not fully grown into an adult cat until they are 3-years-old. The Somali cat breed is also not considered an adult by turning a year old, but are fully grown and into adulthood when they are just under 3-years-old.

Overall, the breed of a cat has a very large impact on what age they are grown into an adult cat and are fully grown.

2. Growth Based on Their Feeding Schedule

Growth Based on Their Feeding Schedule

Interestingly enough, the growth of a cat also depends highly on their requirements for nutrition and calories. Though they have smaller stomachs, this is a very large factor in how fast their growth development goes.

While free feeding a kitten is a more convenient way for them to eat on their own terms, having a schedule can help them grow “better”. In fact, free feeding can lead to obesity very quickly, but it can also help kittens who are either underweight or have a slow growth happening grow much faster.

Overall, a consistent amount of food per meal should be followed. The general guideline for a meal where kittens are concerned is approximately 3/4 of a cup of dry food each meal, offered three to four times per day. Twice per day feedings should be switched when they are approximately 6-months-old.

Because growth varies by breed and their feeding schedule, the results can be mixed greatly in the full growth department, so doing some extra research on your part may be necessary.

Keep in mind that the growth of a cat can be helped or hindered based on their food intake. For example, a cat will grow much more slowly if their nutritional needs and requirements are not met, whereas a cat who is getting everything they need food wise will grow much faster.

For example, a kitten’s growth can be slowed if they do not have enough zinc, iron, potassium, sodium and magnesium. Calcium, if kittens have too much of it, can cause slower growing bones that become more dense, which will stunt their growth greatly.

3. Their Bones

Their Bones

Because kittens don’t stay small for very long, unless they are of a munchkin-like breed, the bones must be assessed for the purpose of figuring out when do cats stop growing. Kittens, in general, have a very steep curve where growth is concerned, especially during their first 6 to 9 months of life.

Their bones grow to the size of their body, which increases exponentially over time. By the time they have reached sexual maturity, which we will read about later on, their bones will have grown to the full size and they will further develop from there.

However, again, this all depends on the span of growth based on the breed, their feeding schedule and what they are eating/how often, etc.

4. Their Skin

Their Skin

Their skin is also a very large and important factor as to when do cats stop growing and are considered fully grown. During the first 6 to 9 months, like their bones, their skin growth and development affects their size.

This period is where a cat typically fattens and fills up, which is a process that, again, varies highly by the breed he or she is. However, their skin is typically done growing and developing by the first year of their life, if not a year and a half.
