Maine Coon Cats: Grown Size And What To Expect

The Maine Coon cat is the largest domesticated cat breed in the world. On average, male Maine Coons weigh between 13 and 25 pounds, with females weighing between 8 and 15 pounds. They don't reach their full size until they are three to five years old. Maine Coons are well-adapted to cold climates and are known for their friendly, laid-back personalities. They can make great family pets as they are relaxed, intelligent, and affectionate.

Weight: Males 13-18 lbs, females 8-12 lbs

The Maine Coon is a large domesticated cat breed native to the US state of Maine, where it is the official state cat. It is one of the largest domesticated cat breeds and is often referred to as the "gentle giant".

The weight of a Maine Coon cat depends on its genetics and diet. On average, male Maine Coons weigh between 13 and 18 pounds, while females weigh between 8 and 12 pounds. However, it is not uncommon for a Maine Coon cat to weigh up to 30 pounds, but such cats are considered overweight or obese and are at risk of developing health issues.

The weight of a Maine Coon cat can be affected by its diet. A healthy diet rich in nutrients can help a Maine Coon reach its maximum size potential. On the other hand, a diet full of empty calories will result in a fat cat that is not healthy. Maine Coons also need regular exercise to maintain a healthy weight, and many owners train their cats to walk on a leash and harness.

Maine Coons are slow to mature physically and may take up to five years to reach their full size. During their growing cycle, they can gain up to 2 pounds per month, so it is important to monitor their weight to prevent health issues.

Maine Coons are well-adapted to cold climates and have several physical adaptations for survival in harsh winter conditions. Their dense water-resistant fur is longer and shaggier on their underside and rear, providing extra protection from wet and icy surfaces. Their long and bushy tail can be curled around their face and shoulders for warmth and protection from the wind and snow. Their large paws, often compared to snowshoes, facilitate walking on snow, and the long tufts of fur between their toes provide extra warmth.

Height: 10-16 inches

The Maine Coon is one of the largest domestic cat breeds in the world. Male Maine Coons stand tall at a height of 10-16 inches (25.5-40.64 cm), while female Maine Coons are slightly shorter at 8-14 inches (20.32-35.56 cm). These height differences between the genders are slight, with some crossover. Indeed, it is possible for a female Maine Coon to be taller than a male.

The height of a Maine Coon is just one aspect of its size, with weight and body length also contributing to its overall size. Male Maine Coons weigh between 15-25 pounds (6.8-11.34 kg), while female Maine Coons weigh about 10% less, at 10-15 pounds (4.54-6.8 kg). The average body length of an adult Maine Coon is 19-40 inches (48-102 cm).

Maine Coons are considered fully grown when they reach 3-5 years of age. Their large size is likely due to a combination of factors, including genetics, nutrition, and environment. Their slow growth rate allows their muscles and skeleton to develop at a more optimal pace.

Maine Coons are often referred to as the "gentle giants" of the cat world due to their loving nature and large size.

Length: Up to 38 inches

The Maine Coon cat is the largest domesticated cat breed in the world. These cats are well-adapted to cold climates and have a long-haired coat, large paws, and a bushy tail. The height of adult Maine Coons can vary between 10 and 16 inches (25 and 41 centimeters), and they can reach a length of up to 38 inches (97 centimeters), including their tail, which can be up to 14 inches (36 centimeters) long.

Male Maine Coons tend to be larger than females, with males weighing in at 13 to 18 pounds (5.9 to 8.2 kilograms) and females weighing in at 8 to 12 pounds (3.6 to 5.4 kilograms). However, it is not uncommon for a Maine Coon cat to weigh up to 30 pounds (13.6 kilograms), but this is considered overweight or obese and can lead to health issues such as diabetes, heart disease, and arthritis.

The Maine Coon's large size is due to a combination of factors, including genetics, nutrition, and environment. They were originally bred to be barn cats that could withstand harsh winters in the Northeastern United States. Their long hair, large paws, and bushy tails are all adaptations that help them stay warm in cold climates.

Maine Coons are also known for their friendly and laid-back personalities. They are often referred to as "gentle giants" and make great family pets as they enjoy human company and get along well with children and other pets.

Overall, the Maine Coon cat is a large and impressive breed, not just in terms of length but also in terms of weight, coat, and temperament.

Coat colours: black, lavender, tabby, blotched, ticked

The Maine Coon cat is a large domesticated cat breed, native to the US state of Maine. They are known for their size, dense coat of fur, and valuable hunting skills.

Maine Coons can have a variety of coat colours, including black, lavender, tabby, and blotched or ticked patterns.

Black

The black Maine Coon is not a separate breed but one of the few colours that these cats are available in. The breed standard, according to the Cat Fanciers' Association, requires the cat to be a dense coal black from the roots to the tips of its fur. Black Maine Coons must not have any tinge of rust on their fur tips or a smoke undercoat. Their paw pads need to be black or brown.

Lavender

Maine Coons can also be lavender, though this colour is not accepted by some breed standards.

Tabby

Tabby Maine Coons can come in two different patterns: mackerel or classic. A mackerel tabby has stripes running down its body, with a connecting stripe down its back. A classic tabby has stripes on its legs, face, and tail, with a random swirl pattern on its body.

Blotched

Blotched tabby Maine Coons have large streaks in the form of a bullseye on their sides.

Ticked

The ticked tabby pattern is characterised by an alternation of light and dark areas on each hair of the cat's coat.

Health issues: hip dysplasia, hypertrophic cardiomyopathy, gingivitis, spinal muscular atrophy

The Maine Coon is a large domesticated cat breed known for its majestic appearance and sociable temperament. While these cats are generally healthy, they are prone to certain health issues, including hip dysplasia, hypertrophic cardiomyopathy, gingivitis, and spinal muscular atrophy.

Hip Dysplasia

Hip dysplasia is an orthopedic condition that occurs when the ball-and-socket joint connecting the cat's thigh bone (femur) to its hip is misaligned and loose. This results in a partial dislocation, causing the femoral head and the acetabulum (socket) to grind against each other. Over time, this constant wear and tear leads to osteoarthritis, characterised by the destruction of cartilage that cushions the bone ends. Clinical signs of hip dysplasia in cats include limping, avoidance of physical activity, expression of pain when the hip is touched, and persistent licking or chewing at the hip area. Obesity is believed to be a contributing factor by increasing pressure on the hip joint. Prevention and treatment options are limited, but maintaining a healthy weight and encouraging exercise can help. In advanced cases, surgical options such as total hip replacement or femoral head ostectomy may be considered.

Hypertrophic Cardiomyopathy (HCM)

HCM is the most commonly diagnosed cardiac disease in cats and is characterised by a thickening of the muscular walls of the heart's left ventricle, leading to decreased heart efficiency. This condition can cause the heart to beat rapidly, resulting in increased oxygen consumption and possible oxygen starvation of the heart muscle. HCM can lead to congestive heart failure, the formation of blood clots in the heart, and sudden death. Many cats with HCM may not appear ill, while others may show signs such as rapid breathing, lethargy, and open-mouthed breathing due to lung congestion. HCM is diagnosed through echocardiography, and while there is no cure, specialised care and medication can help manage the condition.

Gingivitis

Gingivitis is an inflammation of the gums surrounding the teeth, caused by plaque buildup and poor oral hygiene. Signs of gingivitis in cats include red or swollen gums, difficulty eating, and plaque buildup on the teeth. If left untreated, gingivitis can cause significant oral pain and discomfort, and in extreme cases, cats may have trouble eating. Treatment for gingivitis involves tooth cleaning under anaesthesia to remove plaque and treat diseased teeth. Maintaining proper oral hygiene through regular brushing with cat-specific toothbrushes and toothpaste is crucial to prevent gingivitis in cats.

Spinal Muscular Atrophy (SMA)

SMA is a genetic disease characterised by progressive instability and posture abnormalities due to the loss of motor neurons in the lower spinal cord and muscle atrophy in the hind limbs. Kittens typically start showing signs of SMA at around 3-4 months of age. Affected cats may exhibit an unsteady gait, trembling, and weakness in the hind limbs. SMA is not painful or fatal, and cats can live a comfortable life with the condition. It is inherited as an autosomal recessive trait, and genetic testing can help breeders avoid producing affected kittens.
