Common Health Issues in Cats: Warning Signs and How Routine Bloodwork Helps

Cats are masters at hiding illness, which is why many health problems go unnoticed until they become serious. Regular veterinary care, including routine bloodwork, is key to catching issues early and keeping your cat healthy for years to come. Here’s a guide to some of the most common health problems in cats, along with warning signs and possible treatments.

1. Kidney Disease

Kidney disease is common in older cats and can progress slowly over time.

Warning Signs:

• Increased thirst and urination

• Weight loss or decreased appetite

• Lethargy or vomiting

Possible Treatments:

• Prescription diets designed for kidney support

• Medications to manage symptoms like nausea or blood pressure

• Regular monitoring through blood and urine tests

Why Bloodwork Helps: Routine bloodwork can detect early kidney function changes before obvious symptoms appear, allowing for earlier intervention.

2. Hyperthyroidism

Hyperthyroidism occurs when the thyroid gland produces too much hormone, affecting metabolism.

Warning Signs:

• Weight loss despite a good appetite

• Increased activity or restlessness

• Vomiting or diarrhea

Possible Treatments:

• Prescription medication to control thyroid hormone

• Special diets low in iodine

• Surgical or radioactive iodine therapy in some cases

Why Bloodwork Helps: Blood tests can detect abnormal thyroid hormone levels early, often before noticeable weight loss or behavioral changes occur.

3. Diabetes

Diabetes in cats is often related to obesity and can affect insulin regulation.

Warning Signs:

• Increased thirst and urination

• Weight loss despite eating normally

• Lethargy or weakness

Possible Treatments:

• Insulin therapy

• Special prescription diets to manage blood sugar

• Regular monitoring of blood glucose levels

Why Bloodwork Helps: Routine bloodwork can identify elevated glucose levels early, even before severe symptoms develop, allowing for earlier treatment.

4. Dental Disease

Dental issues are very common in cats and can affect overall health.

Warning Signs:

• Bad breath

• Drooling or pawing at the mouth

• Difficulty eating or decreased appetite

Possible Treatments:

• Professional dental cleaning under anesthesia

• Tooth extraction if necessary

• Dental diets or chews to reduce tartar buildup

Why Bloodwork Helps: Bloodwork before anesthesia ensures your cat is healthy enough for dental procedures and helps detect underlying conditions that may complicate treatment.

5. Heart Disease

Heart disease can occur in cats at any age, sometimes without obvious early signs.

Warning Signs:

• Rapid or labored breathing

• Coughing or exercise intolerance

• Lethargy or weakness

Possible Treatments:

• Medications to manage heart function and blood pressure

• Special diets for heart support

• Regular monitoring with blood tests and imaging

Why Bloodwork Helps: Blood tests can identify organ strain or imbalances that indicate early heart disease before severe symptoms appear.

Bonus Tip: Routine Bloodwork is Key

Many of these health issues develop gradually, and cats are experts at masking illness. Annual or biannual bloodwork allows your veterinarian to detect changes early, sometimes before your cat shows any outward signs of disease. Early detection often means simpler, more effective treatment and a better long-term prognosis.

Our Recommendation

Don’t wait for symptoms to appear—schedule regular wellness exams and bloodwork for your cat. Paired with proper diet, vaccinations, and preventive care, early detection can help your cat live a longer, healthier, and happier life.
