Maine-coons are truly amazing creatures that are able to make an indelible impression on a person who sees them for the first time. These luxury cats are very large, especially compared to most other breeds. Their faces look more serious and even a bit harsh, but this does not mean that the Maine Coons are cruel and aggressive animals. Today we will take a closer look at these unusual pets and find out how their weight varies depending on age.


Luxurious representatives of the famous breed Maine Coon are amazing creatures. Due to the unusual external data of these pets it is difficult to confuse or not find out. The main distinguishing feature of the Maine Coon is their large size and impressive weight. According to experts, Some adults can reach a weight of a couple of tens of kilograms. The standard parameters for females are usually 5-8.5 kg, and males - 8-12 kg. These figures are unusual for most cats.

Since adults are heavy, kittens are usually born larger. They are developing rather than their fellow breeds.

The growth of small Maine Coons surprises with its speed.

Distinguish Maine Coons from other subspecies and other interesting features. For example, special attention is attracted by fluffy frill collars, formed from high-quality and thick wool. Such details make the appearance of this unusual cat even more solid and rich. The tail of the Maine Coon grows no less elegant and fluffy.

From the outside, these pets look like smaller copies of lions or other wild cats, which attract a lot of attention.

Growth Factors

Before proceeding directly to the consideration of all the weight norms of the Maine Coon, It is necessary to get acquainted with the list of the main factors influencing the growth of these amazing animals.

  • Floor. This is one of the most important factors affecting the development of pedigreed kittens. Kitten boys will always be more impressive in size than girls.
  • Genes. Genetics play a significant role in the growth of kittens. Large individuals and kittens will be born large. As a rule, they grow larger and heavier, along with their closest relatives.
  • The physical state just born kitten. Babies who were born weak will grow less rapidly and are unlikely to grow very large.
  • The large number of litter. Kittens that come from a small litter are born more large and strong. If the litter is numerous, then the kids are unlikely to be large.
  • Conditions that contain the mother cat in the period of carrying and feeding offspring. If the cat eats all the days of gestation and feeding with balanced feed and products, is kept in optimal and comfortable conditions for it, then it will definitely bring healthy and high-quality offspring. Such kids will grow as it should.
  • Stressful situations. If in a house where cats are kept, a rather restless situation is constantly observed, if the owners often shout and swear, make noisy repairs, then the changed usual rhythm of life of the Maine Coon can lead to severe stress. As a result, a purebred kitten can grow much more slowly than in calm conditions.
  • Past illnesses. Kittens that have suffered various kinds of diseases grow at times worse than their healthy counterparts who did not suffer from anything. In some cases, growth does not just slow down, but stops at all.
  • Feeding. In order for a pet to grow well in accordance with its age, it is necessary to provide it with proper, balanced and nutritious nutrition. No need to buy a cheap kitten economy class feed or give food from the human table.

Make for a thoroughbred baby a good menu, which will contain only high-quality products or premium premium ready-made premium foods.

A lot of adult cats

It is possible to find out the exact and final weight of the Maine Coon only at the moment when it will be 3 years old. Until that time, your home furry giant will grow.

Mature Maine Coon females, who have already turned 3 years old, in weight can reach about 4.5 or 7.5 kg, and males - 8-10 kg. These indicators are average. Of course, your pet may grow with other indicators of weight. The length of these original pets is usually 120 cm, so it’s hard to believe that their weight can be only 4.5 or 8 kg. If the owner is closely watching the growth rate of his animal and the amount of food consumed by him, the cat can reach 15 kg in weight.

True, not always such values ​​are the norm. Often overweight maine coons are associated with obesity.

Record weight of an adult individual is 20 kg or more. By the way, this figure is listed in the Guinness Book of Records.

Why the cat does not grow or lose weight?

It so happens that even a small Maine Coon is growing poorly. If the baby is almost not gaining mass, then this is a bad sign. It is considered that the main factors that negatively affect the growth of kittens of this breed are the following factors.

  • Poor food mom cats. Nursing Maine Coon females must be fed at least 3 times a day. It is necessary to give them special high-quality feed for lactating individuals.
  • If the kitten is too small, it may simply not suck the mother's milk.. Another reason may be that the cat has too little milk. So that the baby can get enough, some owners resort to additional feeding with a special substitute for cat milk.
  • The cause may be mother's milk containing toxins. This product can have a bad effect if the female is ill with mastitis, metritis or uterine abscess. The kitten should not drink the same kind of milk that a cat gives, using various medications and antibiotics.
  • Anemia and lack of vitamins in the body - Another common reason that prevents Maine Coon kittens from growing normally. If breast milk lacks all the necessary substances, the baby may be weak and small in size.
  • The cause of poor growth and development of a kitten can be worms.. These dangerous parasites in many situations move from mother to offspring through milk. Of course, the worms will not give the kitten any chance for normal growth. In such situations, you must act as soon as possible and contact your veterinarian.
  • Maine Coon babies can grow poorly due to a certain genetic abnormality.. It happens that among several kittens one weighs less than all and looks very weak from the outside.Similar problems arise in humans when one of the twins looks completely healthy, and the second is barely alive.
  • Some diseases can be the main reason why a kitten cannot grow normally. Most often - these are diseases that are transmitted to the baby from the mother. Some diseases develop independently, without participation of the female. If the kitten clearly feels unwell (it vomits, the chair is broken and the temperature has risen), then you should rather go to the vet or call the doctor at home. To pull time in such situations is very dangerous.
  • If a purebred Maine-Coon breed produced kittens from a non-purebred male, then the kitten may face growth problems. Of course, such problems are very rare, but they must be taken into account.

    There are cases when Maine-Coon begins to lose weight. Such changes suggest that there is a serious problem that needs to be addressed as soon as possible. The most common cause of weight loss are the following factors:

    • the presence of parasites in the cat or cat (parasites can be both external and internal) is one of the most common causes of weight loss;
    • extra stress and nervous shocks;
    • improperly formulated and unbalanced diet, which lacks all the necessary vitamins and supplements;
    • hormonal disbalance;
    • a sharp change in the usual diet (any changes in the diet should be carried out gradually so as not to harm the health of the animal);
    • problems with the state of the gastrointestinal tract;
    • oncological diseases.

      Often, the weight loss of the Maine Coon is accompanied by other disturbing symptoms. For example, it can be constipation, alternating with diarrhea (standard signs in case of infection with animal worms).

      If the pet is experiencing serious stress, then it will not only lose weight, but also behave too restlessly, atypically for his usual mood.
