Why Does My Cat Have A Small Head – Unveiling the Mystery

Cats can vary in their physical characteristics, including their size and shape. These features can provide insights into their overall well-being. It is not uncommon for cat owners to be worried about the size of their cat’s head. If you have ever pondered why your cat has a small head, you are not alone.

A cat’s head can be small due to its gender, breed, and body structure. Neutered male cats also tend to have smaller heads. If a cat has a small head, it could mean that it is not fully grown.

Let’s examine what a typical cat head size is and whether you should be concerned about your cat’s head size.

Will My Cat’s Head Get Bigger

Yes, similar to humans, cats’ heads get bigger as they get older. When I got my Persian Mix kitten, he was a cute little furball weighing 2.5 pounds. Now he’s around 12 pounds, and his head is as big as his entire body was when he was a kitten.

Cats usually reach their full size by the time they are about one year old, although there are some breeds that may take longer. If your cat is almost a year old and you feel like their head is too small, it’s a good idea to make an appointment with your vet. They can examine your cat for any potential issues. It’s important to note that most abnormalities tend to make a cat’s head bigger, not smaller.

If your cat belongs to the Maine Coon, Persian, or Siberian breeds, these cats continue to grow beyond one year of age. Male cats also reach their full size later than female cats. Even though my cat is not a purebred Persian, he continued to grow until he was nearly two years old.

In simple terms, your cat’s head will indeed grow larger, and you just need to be patient.

What Breed Of Cat Has A Small Head

Certain cats have a small head because they belong to petite breeds. The Devon Rex, Cornish Rex, and Munchkin cats are small in size, which is why they have small heads. Siamese cats are also relatively small, so their heads are smaller than the average size.

For all these breeds, their head size will be in proportion to their bodies. They simply have a small head that matches their small bodies. Singapuras and American Curls are also small cats, and they have small heads to match. Some Scottish folds also appear to have heads that are smaller than the average size.

When you compare a cat’s head to its body, some cats may appear to have a small head. This is often seen in overweight or obese cats. However, their head is actually a normal size, it’s just that their bodies are larger than they should be. If the cat loses weight and reaches a healthy size, their head will appear normal in proportion to their body.

I have a cat like that. If I leave her alone during feeding, she will boss her brother around and take his food. Because she is overweight, her head looks much smaller compared to her body. There is nothing abnormal about her head; she just needs to lose some weight to have a proportional body.

There isn’t much information available about what is considered a small, regular, or large cat head circumference. This can vary depending on the breed, and even breed-specific websites don’t provide that measurement.

If you want to buy a cat costume or a soft collar for your cat, some products will determine the size based on the cat’s head size. Although it may be difficult, you can measure the widest part of your cat’s head using a soft measuring tape. If you prefer to buy from a local store, you can bring your cat along and take the measurements there. Some stores may even allow your cat to try on the costume to ensure comfort and proper fit.

Do Unneutered Cats Have Bigger Heads

It’s not a made-up story or a trick of the eyes. Male cats that haven’t been neutered, also known as “tomcats,” have significantly bigger heads compared to neutered cats. When I was a child and spent time on a farm, all the male cats there had huge heads. Since I was young and didn’t know anyone with an indoor cat, I believed that was the normal appearance for male cats. However, that belief is completely incorrect!

The reason why a male cat that hasn’t been neutered has a big head and chubby cheeks is because of the hormones in their body. These hormones, such as testosterone and orientation hormones, are different in male cats that have been neutered. When these substances are absent, the heads and cheeks of neutered cats don’t grow as much as those of unaltered cats. Testosterone and hormones are found in the testicles, which are taken out during the neutering process.

Do Female Cats Have Smaller Heads

Female cats are usually smaller than male cats in terms of their size. Since their body is smaller, their head should also be smaller. However, this is not always true.

Actually, a cat’s head size should match its body size. For example, a female cat weighing six pounds should have a smaller head compared to a male cat weighing twelve pounds.

In certain cases, a fat cat may have a smaller head compared to a healthy cat. However, this is considered normal because the head can only grow to a certain extent in relation to the body.

What Age Is A Cat Fully Grown

The answer to this question depends on the type of cat you have. Most domestic cats reach their full size when they are around one year old. Although they will continue to mature, their bodies will stop growing. However, certain breeds have longer growth periods and may not reach their full physical size until several years later. For example, Persian males may take 2-3 years to be fully grown, while Maine Coons and Siberians can take as long as 3-5 years. During this extended growth period, their heads will also continue to develop.

If you have a cat with a small head, it’s important to talk to your vet about it. There is a condition called cerebellar hypoplasia that affects the growth of a cat’s brain. This condition results in the improper development of the cerebellum, which can cause difficulties with walking and other tasks controlled by that part of the brain. Cats with this condition may experience intense shaking, but they don’t feel any pain. It’s best to consult a vet to determine if the condition affects the cat’s skull. Any cat with this condition will show visible signs of it.

Hydrocephalus is a different condition that can affect the size and form of a cat’s skull. It is also known as water on the brain. It affects the ventricular system of the brain by irritating or blocking vessels. Cats with this disorder will have heads that are an uncommon shape. This condition typically leads to a bigger head, but it’s best to consult a vet for a proper diagnosis.


There are several factors that can affect the size of a cat’s head, such as its gender, breed, whether it has been neutered, and its body weight. Even in smaller cat breeds, it is important for their heads to be proportionate to the rest of their body. If you believe that your cat’s head is too small compared to its body, it is recommended to consult with your veterinarian to rule out any potential medical conditions. While rare, there are certain conditions that can affect a cat’s brain size or skull development.

But don’t get too ahead of yourself. Although most cats stop growing by the age of one, certain breeds have longer kitten phases. Some breeds continue to grow until they reach five years old. Additionally, remember that male cats finish growing later than females. It’s possible that your cat’s head and body are growing at different rates and will eventually become proportional.
