As cats age, they become more vulnerable to various health conditions that can significantly impact their quality of life. Recognizing these conditions early allows for better management and improved longevity. At Heartland Veterinary Hospital in Danville, KY, we are dedicated to helping pet owners provide the best possible care for their senior cats through preventive medicine and early disease detection.

Recognizing the Signs of Common Senior Cat Diseases

Routine wellness exams are essential for detecting age-related conditions, but pet owners should also monitor for subtle changes in behavior and physical health. Common signs of illness in senior cats include:

  • Changes in appetite or weight
  • Increased thirst or urination
  • Lethargy or reduced activity
  • Unkempt coat or decreased grooming
  • Changes in litter box habits
  • Increased vocalization or withdrawal

Cats instinctively hide signs of illness, making regular veterinary check-ups and close observation at home even more important.

1. Arthritis and Mobility Issues

Arthritis is a degenerative joint condition that causes stiffness, pain, and reduced mobility. Unlike dogs, cats often do not limp when experiencing joint pain but may display subtle behavioral changes, such as:

  • Reluctance to jump onto furniture or climb stairs
  • Increased time spent resting or sleeping
  • Less frequent grooming, especially around painful joints
  • Irritability when touched or picked up

Diagnosis and Treatment

  • X-rays and physical exams confirm arthritis
  • Joint supplements (glucosamine, chondroitin, omega-3 fatty acids) support joint health
  • Pain management with anti-inflammatory medications improves mobility
  • Environmental modifications such as ramps, soft bedding, and elevated food bowls make movement easier

Emergency Warning Signs: Sudden immobility, extreme pain, or refusal to eat should prompt immediate veterinary attention.

2. Chronic Kidney Disease (CKD)

Chronic Kidney Disease (CKD) is one of the most common and serious conditions affecting senior cats. The kidneys lose their ability to filter waste from the bloodstream, leading to toxin buildup in the body.

Signs of CKD

  • Increased thirst and urination
  • Weight loss and muscle wasting
  • Poor appetite and nausea
  • Lethargy and overall weakness

Diagnosis and Management

  • Bloodwork and urinalysis detect kidney dysfunction
  • Prescription kidney diets lower protein and phosphorus intake to reduce strain on the kidneys
  • Hydration therapy (fluid administration) helps manage dehydration
  • Medications manage symptoms such as high blood pressure and anemia

Learn more about CKD from Cornell Feline Health Center.

Emergency Signs: Sudden vomiting, extreme lethargy, or refusal to eat require urgent veterinary attention.

3. Hyperthyroidism

Hyperthyroidism occurs when the thyroid gland overproduces hormones, accelerating metabolism and causing a variety of health issues.

Common Symptoms

  • Increased appetite but noticeable weight loss
  • Hyperactivity or restlessness
  • Increased thirst and urination
  • Vomiting, diarrhea, or changes in coat condition

Diagnosis & Treatment Options

  • Blood tests measure thyroid hormone levels
  • Medications (Methimazole) regulate hormone production
  • Radioactive iodine therapy offers a long-term or permanent cure
  • Prescription diets help manage hormone levels

Read the AAHA guidelines on feline hyperthyroidism.

Emergency Signs: Rapid breathing, heart problems, or severe weight loss indicate immediate medical attention is needed.

4. Diabetes in Older Cats

Diabetes mellitus occurs when a cat’s body cannot regulate blood sugar properly, often due to insulin resistance. Overweight cats are at a higher risk.

Symptoms of Diabetes

  • Increased thirst and urination
  • Weight loss despite a normal or increased appetite
  • Lethargy and muscle weakness
  • Unkempt coat due to decreased grooming

Treatment & Home Care

  • Daily insulin injections may be required
  • Specialized low-carbohydrate diets help regulate blood sugar
  • Routine glucose monitoring ensures proper management

Emergency Signs: Seizures, extreme weakness, or collapse require immediate veterinary attention—these may indicate hypoglycemia or ketoacidosis.
