Spinal muscular atrophy is a neurological disease that affects a cat’s physical abilities but not their cognitive functions.

Maine Coon kittens with spinal muscular atrophy typically show signs when they’re 3–4 months old. They likely have decreased muscle tone and weakness, causing a wobbly walk and tremors.

While the condition requires special care, a cat with spinal muscular atrophy can live a long, happy life.

Polycystic Kidney Disease

Polycystic kidney disease (PKD) is the most common inherited disease in cats. This disease cause fluid-filled cysts in the kidneys, which lead to irreversible damage and kidney failure.

Like HCM, at-home DNA kits can test your cat for PKD before symptoms appear. If you’re working with an experienced Maine Coon breeder, ask if both parents have been genetically tested for the disease.

Hip Dysplasia

If your Maine Coon is avoiding the stairs, not jumping up to their favorite perch, or no longer squatting in the litter box, they might have hip dysplasia.

Cats with hip dysplasia have a genetic condition where the hip joint isn’t formed properly. This can occur in one or both hips, which can lead to arthritis and pain.

Managing hip dysplasia includes weight management, a joint-healthy diet, and (in severe cases) surgery.

Chronic Gingivitis

Gingivitis is inflammation of the gums, and it’s considered the earliest stage of dental disease in cats. While all cats are at risk of gingivitis, Maine Coon cats may be at risk of developing feline juvenile gingivitis when they’re as young as 6 months old.

Brushing your cat’s teeth daily and scheduling routine veterinary exams are the most effective ways to prevent dental disease.

Maine Coon cats can eat a high-quality diet similar to other cat breeds, which includes animal protein-rich food labeled with a nutritional adequacy statement for their life stage from the Association of American Feed Control Officials (AAFCO), Savageau says.

Additionally, Royal Canin offers a diet specially formulated for Maine Coon cats. Pet parents can feed Royal Canin’s Maine Coon food for growth to their Maine Coon kittens, followed by the adult maintenance formula when they reach 2 years of age.
