The 10 American Shorthair Cat Health Problems

1. Obesity

One of the most common health problems in American shorthair cats is obesity. Obesity can cause many other health problems, so keeping your cat at a healthy weight is crucial. A cat is considered overweight when it is 10–20% over its ideal body weight and obese when it is 20% or more over.

Obesity is a serious issue. Overweight adult cats experience almost three times the risk of mortality than lean individuals. If you are not able to get your cat’s weight under control, obesity can lead to health problems such as:

  • Arthritis
  • Diabetes
  • Respiratory problems
  • Heart disease
  • Liver disease
  • Joint pain

Signs

Signs that your cat may be obese include being overweight, having a large waist, and carrying excess fat around the neck and legs. Other signs include:

  • Excessive eating
  • Lack of energy
  • Difficulty moving
  • Breathing problems
  • Difficulty grooming

Treatment

Treating obesity in cats often involves a combination of diet and exercise. The veterinarian can help you create a diet and exercise plan tailored to your cat’s individual needs. To help prevent obesity in your American shorthair cat, make sure to feed them a high-quality diet and provide plenty of opportunities for exercise.

Here are some tips for exercising your cat:

  • Invest in some toy balls or other toys that will encourage your cat to move around
  • Set up a scratching post or cat tree for them to climb
  • Take them on walks with a harness and leash (this is especially good for indoor cats)
  • Have set meal times (don’t “free-fed”)
  • Change to canned food from kibble
  • Consider a weight management diet

2. Diabetes

As mentioned above, diabetes can come secondary to weight issues. It can also be an inherited disease. It occurs when the body does not produce enough insulin, or the cells stop responding to insulin. This can cause an increase in blood sugar levels, which can lead to a host of health problems.

Signs

Some of the signs that your cat may have diabetes include:

  • Increased thirst
  • Increased urination
  • Increased appetite
  • Weight loss
  • Lethargy
  • Poor coat condition

Treatment

If you think your cat may have diabetes, it is important to take them to the veterinarian right away. Diabetes is a serious condition that can be fatal if left untreated. Diabetes treatment usually involves insulin injections and close monitoring.

Here are some tips for managing diabetes in cats:
  • Work with your veterinarian to create a diabetic management plan
  • Feed your cat a high-protein, low-carbohydrate diet
  • Give them insulin injections as prescribed by your veterinarian
  • Monitor their blood sugar levels regularly
  • Visit your veterinarian for regular check-ups

3. Hypertension

Hypertension, or high blood pressure, is another common health problem in American shorthair cats. High blood pressure can lead to various health problems, including heart disease and stroke.

Hypertension is often secondary to another underlying health condition, such as kidney disease or diabetes. Unlike in humans, stress has not been linked to feline hypertension.

Signs

  • Increased urination
  • Increased thirst
  • Restlessness
  • Weight loss
  • Panting
  • Eye issues
  • Blindness
  • Disorientation

Treatment

With proper treatment, hypertension can be managed, and your cat can live a long and healthy life.

Here are some tips for managing hypertension in cats:
  • Work with your veterinarian to create a hypertensive management plan
  • Feed your cat a high-protein, low-carbohydrate diet
  • Give them medication as prescribed by your veterinarian
  • Monitor their blood pressure regularly

4. Heart Disease

Heart disease can be caused by various factors, including genetics, obesity, and hypertension. It can also be congenital, meaning it was present at birth and inherited from the parents. The most common heart disease is hypertrophic cardiomyopathy (enlarging of the heart muscle). Heart disease can cause serious problems, including heart failure and cardiac arrest.

Signs

  • Breathlessness
  • Coughing
  • Exercise intolerance
  • Lethargy
  • Weight loss
  • Stunted growth in kittens
  • Hind leg paralysis

Treatment

Here are some tips for managing heart disease in cats:
  • Feed your cat a high-protein, low-fat diet
  • Give them medication as prescribed by your veterinarian
  • Keep your cat within a healthy weight range
  • Encourage regular light exercise

5. Respiratory Problems

Respiratory problems in cats can be caused by a variety of things, including allergies, infections, and tumors. Allergies are the most common cause of respiratory problems in cats, and infections can also cause respiratory problems in cats and lead to worsening health problems, such as pneumonia.

Signs

  • Sneezing
  • Coughing
  • Wheezing
  • Difficulty breathing
  • Gagging/drooling
  • Runny nose

Treatment

Treatment for respiratory problems depends on the underlying cause. Allergies are often treated with medication, while infections are treated with antibiotics. If your cat has a respiratory problem, it is essential to take them to the veterinarian to receive proper treatment.

Here are some tips for managing respiratory problems in cats:
  • If your cat has allergies, work with your veterinarian to create an allergy management plan
  • If your cat has an infection, give them medication as prescribed by your veterinarian
  • Monitor their breathing regularly and take them to the vet if you notice any changes
  • Avoid exposure to environmental allergens, such as dust, pollen, and cigarette smoke
  • Keep your cat indoors to avoid exposure to infectious diseases

6. Eye Problems

Eye problems in cats can be caused by a variety of things, including infections, trauma, and tumors. Infections are the most common cause of eye problems in cats and can lead to some severe health problems, including blindness. Trauma to the eye can also lead to several ongoing issues and should be treated immediately.

Signs

  • Swelling
  • Redness
  • Discharge
  • Rubbing of the eyes
  • Loss of fur around the eyes
  • Cloudiness

Treatment

Treatment for eye problems depends on the underlying cause. Infections are often treated with antibiotics, eye ointments, and regular cleaning, while trauma may be treated with surgery.

Here are some tips for managing eye problems in cats:
  • Monitor their eyes regularly and take them to the vet if you notice any changes
  • Avoid exposure to environmental allergens, such as dust, pollen, and cigarette smoke
  • Keep your cat indoors to avoid exposure to infectious diseases

7. Urinary Tract Infections

Urinary tract infections (UTIs) are common in American shorthairs and can lead to kidney disease if left untreated. UTIs are most often caused by bacteria that enter the urinary tract through the urethra. Other factors such as spinal injuries, stress, and incontinence may increase the risk of UTIs.

Signs

  • Increased urination
  • Bloody urine
  • Straining to urinate
  • Urinating outside the litter box
  • Lethargy
  • Decreased appetite

Treatment

UTIs are treated with antibiotics. It’s rare for UTIs to go away on their own, so suspected UTIs should be referred to the vet. Many UTI symptoms correlate with lower tract infections, which may be more life-threatening. Proper diagnosis is a must.

Here are some tips for preventing UTIs in cats:
  • Feed your cat a high-protein, low-carbohydrate diet
  • Give them plenty of fresh water to drink
  • Clean their litter box regularly
  • Encourage them to urinate often
  • Take them to the vet for regular check-ups and urine tests

8. Skin Allergies and Skin Conditions

Allergies are the most common cause of skin problems in cats and can cause hair loss, infections, and hot spots. Skin conditions can also be caused by a number of things, including parasites, infections, and tumors.

The occurrence of allegories depends on your cat’s predisposition and exposure to allergens.

Signs

  • Hair loss
  • Itching
  • Sores
  • Scaling
  • Inflammation

Treatment

Treatment for skin problems depends on the cause. Allergies are often treated with medication, while infections are treated with antibiotics.

Here are some tips for managing skin problems in cats:
  • Monitor their skin regularly for changes
  • Avoid exposure to environmental allergens
  • Keep your cat indoors
  • Feed them an allergy-friendly diet
  • Use supplements to support skin health
  • Bathe them regularly with medicated shampoos

9. Ear Infections

Ear infections are caused by bacteria or allergies but can also be due to many other causes such as tumors, diabetes, foreign bodies, wax build-up, and immune system diseases. Complications can be severe and increase deafness and facial paralysis. Luckily, ear infections are uncommon in cats.

Signs

  • Shaking their head
  • Scratching their ears
  • Holding their head tilted to one side
  • Discharge from their ears
  • Bad odor
  • Hair loss around their ears

Treatment

Treating a cat ear infection will generally be done using antibiotics or antibacterial medicine. Your vet will inspect the ear to identify the cause of the infection for further treatment.

In the rare case of chronic ear infections, surgery may be required to remove tissue blocking the ear canal.

Here are some tips for managing ear infections in cats:
  • Keep their ears clean and free of dirt and debris
  • Apply medication as directed by your veterinarian

10. Dental Problems

Dental problems include a number of issues such as infections, tooth loss, and gum disease. Dental problems are most often caused by plaque and tartar build-up on the teeth. Dental-related issues are super common, with studies showing that 50–90% of cats will suffer from dental disease in their lives.

Most are preventable and easily treatable, but they can cause a degree of pain and discomfort (we’ve all been there, right!)

Signs

  • Bad breath
  • Drooling
  • Pawing at their mouth
  • Difficulty eating

Treatment

Dental problems are treated by cleaning the teeth and removing any plaque or tartar build-up. Your veterinarian may also recommend dental surgery to remove any damaged teeth.

Here are some tips for preventing dental problems in cats:
  • Feed them a high-quality diet
  • Give them plenty of fresh water to drink
  • Brush their teeth regularly with a toothbrush and toothpaste designed for cats
  • Take them to the vet for regular dental check-ups and cleanings
