Diseases of the American Shorthair - A beauty with character
Origin and History of the American Shorthair
The American Shorthair is one of the oldest and best-known cat breeds in the USA. Originally brought by European settlers, the breed developed into a robust, versatile and independent cat in North America. Their origins lie in the crossing of farm cats, which were specifically valued for their hunting abilities, with breeds from Europe. Over time, a breed emerged that is not only physically attractive, but also impresses with its health and friendly nature.

Physical characteristics of the American Shorthair
The American Shorthair is a medium to large cat with a muscular, powerful build. Their appearance is both elegant and powerful, which makes them particularly attractive.
height and weight
- Size: 30 to 35 cm
- Weight: 4 to 7 kg (males) and 3 to 5 kg (females)
These cats grow slowly and often only reach their full size and weight after 3 to 4 years. Males are generally heavier and stronger than females.
Fur and colors
The short, dense coat of the American Shorthair is another characteristic feature. It protects the cat from extreme weather conditions while being easy to care for.
- Coat length: Short, smooth and dense
- Coat Colors: There is an impressive variety of colors and patterns including silver tabby, black, white, blue, cream and many more.
The coat is easy to care for and only requires occasional brushing, especially during shedding in spring and fall.
Eyes
The American Shorthair's eyes are large, round and radiate attention. The color of the eyes varies from green to gold to blue, adding to the grace of this breed.
Character and essence
The American Shorthair is known for its friendly, even-tempered and adaptable nature. These cats are ideal companions for both families and individuals as they can easily adapt to different living conditions.
Social behavior
This breed is sociable and gets along well with children, other cats and dogs. She is curious and loves to play, but at the same time has a calm and patient nature, which makes her suitable for busy households. American Shorthairs are very people-oriented and enjoy the company of their owners, but are not overly affectionate. You can also be left alone without developing separation anxiety.
Activity level
Although the American Shorthair is a relatively calm breed, they love to play and explore their surroundings. She appreciates interactive toys and needs mental stimulation to avoid boredom. Nevertheless, these cats are also excellent cuddle partners and know how to enjoy quiet moments.
Diseases in the American Shorthair - symptoms, diagnosis, treatment and prevention
Although the American Shorthair is considered a healthy and robust breed, it is not completely immune to hereditary diseases. The most common genetic diseases that owners should watch out for include hypertrophic cardiomyopathy (HCM) and polycystic kidney disease (PKD) . Here is detailed information about these and other potential inherited diseases:
1. Hypertrophic cardiomyopathy (HCM)
Hypertrophic cardiomyopathy is one of the most common heart diseases in cats, including the American Shorthair . This causes the heart muscle to thicken, which impairs heart function.
Symptoms:
- Fast, shallow breathing
- Shortness of breath, especially after physical activity
- Reduced activity and reluctance to move
- Sudden attacks of fainting
- Heart murmurs that can be detected during a routine examination
- In advanced cases: fluid accumulation in the lungs (pulmonary edema)
Diagnosis:
- Auscultation (listening to the heart): Heart murmurs can be an early sign of HCM.
- Ultrasound (echocardiography): This is the most accurate method to diagnose HCM. The veterinarian can measure the thickness of the heart muscle and assess the function of the heart.
- X-ray: May show evidence of enlargement of the heart or fluid in the lungs.
- ECG (Electrocardiogram): Records the heart's electrical activity and helps identify abnormal heart rhythms.
Treatment:
- Medication: There is no cure for HCM, but medications such as beta blockers, calcium channel blockers, or ACE inhibitors can help relieve symptoms and reduce strain on the heart.
- Diuretics: When fluid builds up in the lungs, diuretics are used to make breathing easier.
- Long-term monitoring: Regular veterinary visits to check heart function and adjust medications are essential.
Prevention:
Since HCM is genetic, there are no specific preventive measures. However, reputable breeders regularly have their breeding animals tested for HCM in order to exclude affected cats from breeding. When purchasing an American Shorthair, it is advisable to find out about the health of the parents.
2. Polycystic kidney disease (PKD)
Polycystic kidney disease is a genetic disorder in which cysts form in the kidneys. These cysts grow over time and affect kidney function, which can eventually lead to kidney failure.
Symptoms:
- Increased thirst and more frequent urination
- Loss of appetite
- weight loss
- Vomit
- lethargy
- Poor coat and general physical deterioration in advanced stages
Diagnosis:
- Ultrasound examination of the kidneys: The veterinarian can use an ultrasound device to visualize cysts in the kidneys. Cysts can be detected at a young age.
- Blood and urine tests: These tests help check kidney function and assess the severity of the disease.
Treatment:
- Symptomatic Treatment: There is no cure for PKD, so treatment focuses on relieving symptoms and slowing disease progression.
- Diet management: Kidney-friendly foods with low protein content can help reduce the strain on the kidneys.
- Fluid therapy: In advanced cases, intravenous or subcutaneous fluid therapy is often used to support the cat's fluid balance.
- Medications: ACE inhibitors or other medications may be used to lower blood pressure and support kidney function.
Prevention:
The best prevention measure is to only purchase cats from breeders that perform PKD testing on their animals. Cats that carry the gene should not be used for breeding to prevent the spread of this disease.
3. Inflammation of the gums (gingivitis)
Dental problems like gingivitis are not specifically hereditary, but they are relatively common American Shorthair Gingivitis is an inflammation of the gums caused by plaque or infection.
Symptoms:
- Redness and swelling of the gums
- Bad breath
- Loss of appetite or difficulty eating
- Increased salivation
- Pain when chewing
Diagnosis:
- Oral Exam: A veterinarian can easily detect gum inflammation through a visual examination.
- X-ray: To assess whether the inflammation also affects the jawbone, an X-ray of the teeth and jaw can be taken.
Treatment:
- Teeth cleaning: Professional teeth cleaning under anesthesia may be necessary to remove plaque and tartar.
- Antibiotics: If inflammation is severe, the vet may prescribe antibiotics to fight the infection.
- Dental care at home: Regular brushing with special cat toothbrushes and pastes can prevent future problems.
Prevention:
The best prevention is regular dental hygiene. This includes brushing your teeth daily, using tooth-friendly food and regular check-ups at the vet.
4. Feline Infectious Peritonitis (FIP)
FIP is a fatal viral disease caused by the feline coronavirus. This disease occurs primarily in young cats and there is no cure.
Symptoms:
- Fever
- Loss of appetite
- weight loss
- Fluid accumulation in the abdominal cavity (wet form)
- Neurological symptoms (dry form)
Diagnosis:
- Blood tests: There are specific tests that can detect coronavirus, but diagnosing FIP remains complicated and is often based on a combination of symptoms and tests.
- Ultrasound and X-rays: Fluid collections can be made visible using imaging techniques.
Treatment:
- There is no cure for FIP. Treatment focuses on relieving symptoms and supporting the cat's immune system.
- Novel antiviral drugs: Some experimental treatments have recently helped certain cats, but these are often not yet widely available.
Prevention:
Because FIP is caused by the coronavirus, which is often spread through close contact, isolating infected cats and practicing good hygiene in multi-cat households is the best prevention.
The American Shorthair is a relatively healthy cat breed, but as with any purebred cat, genetic diseases can occur. A thorough examination of the health of the parents and regular check-ups at the vet are essential to minimize the risk and ensure the well-being of the cat.

Frequently asked questions about American Shorthair diseases
Which genetic diseases are particularly common in the American Shorthair and how can I ensure that my cat is healthy?
The American Shorthair is generally a healthy breed, but like many purebred cats, it can develop genetic diseases. The most common diseases include hypertrophic cardiomyopathy (HCM) and polycystic kidney disease (PKD) .
Hypertrophic cardiomyopathy (HCM) is a heart disease that causes the heart muscle to thicken. This disease can lead to heart failure and often shows no symptoms in the early stages. With advanced HCM, the cat may have breathing problems, weakness, or fainting spells. Early diagnosis through ultrasound scans is crucial to begin appropriate treatment.
Polycystic kidney disease (PKD) causes cysts to form in the kidneys, which can affect kidney function. PKD is hereditary, and cats with the condition may develop symptoms such as increased thirst, loss of appetite, and weight loss. A regular ultrasound of the kidneys can help detect PKD early.
