Most Common Health Problems in Senior Cats

As cats age, they become more susceptible to various health issues. Senior cats, typically considered those over the age of seven, require special attention and care to manage their health effectively. Understanding the most common health problems in senior cats can help pet owners provide the best care for their aging feline companions.

Aging in Cats

As cats age, they undergo several physiological changes. Recognizing the signs of aging, such as decreased activity, weight changes, and altered sleeping patterns, is crucial for early intervention and effective management of health issues.

Arthritis and Joint Issues

Symptoms: Senior cats with arthritis may show signs of stiffness, limping, difficulty jumping, and reduced mobility. They might also be less active and more irritable.

Diagnosis: Diagnosis typically involves a physical examination, X-rays, and sometimes blood tests to rule out other conditions.

Treatment and Management: Treatment options include weight management, pain relief medications, joint supplements, and physical therapy. Ensuring a comfortable living environment with easy access to essentials can also help.

Kidney Disease

Causes: Chronic kidney disease (CKD) is common in older cats and can result from aging, genetic factors, or previous kidney damage.

Symptoms: Increased thirst and urination, weight loss, poor appetite, and vomiting are common signs.

Diagnosis: Blood tests, urinalysis, and ultrasound are used to diagnose CKD.

Treatment: While CKD is not curable, it can be managed with a special diet, medications, and regular vet check-ups to monitor kidney function.


Symptoms: Hyperthyroidism causes increased metabolism, leading to weight loss, increased appetite, hyperactivity, and vomiting.

Diagnosis: Blood tests measuring thyroid hormone levels confirm hyperthyroidism.

Treatment Options: Treatment options include medication, radioactive iodine therapy, surgery, and dietary management.

Diabetes Mellitus

Causes: Diabetes in cats can be caused by obesity, genetic factors, or other health issues.

Symptoms: Increased thirst and urination, weight loss, increased appetite, and lethargy are common signs.

Treatment and Management: Management includes insulin injections, dietary changes, and regular blood glucose monitoring.

Dental Disease

Common Dental Issues: Senior cats often suffer from periodontal disease, gingivitis, and tooth resorption.

Prevention: Regular dental check-ups, professional cleanings, and at-home dental care can help prevent dental diseases.

Treatment: Depending on the severity, treatment may include dental cleaning, extractions, and antibiotics for infections.

Heart Disease

Types: Common heart diseases in senior cats include hypertrophic cardiomyopathy (HCM) and congestive heart failure (CHF).

Symptoms: Symptoms include lethargy, difficulty breathing, coughing, and fainting.

Diagnosis: Diagnosis typically involves physical exams, chest X-rays, echocardiograms, and blood tests.

Treatment: Treatment options include medications to manage symptoms, dietary changes, and regular veterinary monitoring.

Cancer in Senior Cats

Common Types: Lymphoma, squamous cell carcinoma, and mammary gland tumors are prevalent in older cats.

Symptoms: Symptoms vary depending on the cancer type but may include lumps, weight loss, lethargy, and changes in behavior.

Treatment Options: Treatment may involve surgery, chemotherapy, radiation therapy, and palliative care.


Causes: Obesity in senior cats can result from overfeeding, lack of exercise, and metabolic changes.

Risks: Obesity increases the risk of diabetes, arthritis, and heart disease.

Prevention and Management: Prevention includes a balanced diet and regular exercise. Managing obesity involves portion control and veterinary guidance on weight loss.

Loss of Appetite

Causes: Loss of appetite in senior cats can be due to dental problems, illness, or changes in metabolism.

Symptoms: Refusal to eat, weight loss, and lethargy are common signs.

Solutions: Addressing the underlying cause, providing palatable food, and sometimes appetite stimulants can help.

Hearing and Vision Loss

Signs: Signs of hearing loss include not responding to sounds or being startled easily. Vision loss may present as bumping into objects or reluctance to move in unfamiliar environments.

Adaptation and Care Tips: Maintain a consistent environment, use visual or tactile cues, and ensure safety at home.

Cognitive Dysfunction Syndrome

Symptoms: Symptoms include disorientation, changes in sleep patterns, decreased interaction, and house soiling.

Management and Treatment: Management includes maintaining a routine, providing mental stimulation, and using medications to slow progression.

Urinary Tract Issues

Common Problems: Common issues include urinary tract infections (UTIs) and feline lower urinary tract disease (FLUTD).

Symptoms: Symptoms include frequent urination, straining, blood in urine, and urinating outside the litter box.

Treatment: Treatment may involve antibiotics for infections, dietary changes, and increased water intake.


Causes: Hypertension in cats can be primary or secondary to other conditions like kidney disease or hyperthyroidism.

Symptoms: Symptoms include sudden blindness, seizures, and disorientation.

Diagnosis and Treatment: Blood pressure monitoring and treating underlying conditions are essential. Medications can manage high blood pressure.

Digestive Problems

Common Issues: Common digestive problems include constipation, diarrhea, and inflammatory bowel disease (IBD).

Symptoms: Symptoms include changes in stool consistency, vomiting, and abdominal discomfort.

Treatment: Treatment may involve dietary changes, medications, and addressing underlying causes.

Skin and Coat Problems

Common Issues: Senior cats may experience hair loss, dry skin, and infections.

Treatment and Prevention: Regular grooming, a balanced diet, and veterinary care for skin conditions can help maintain skin and coat health.

Respiratory Issues

Common Problems: Respiratory problems include asthma, chronic bronchitis, and infections.

Symptoms: Symptoms include coughing, wheezing, and difficulty breathing.

Treatment: Treatment may involve medications, environmental changes, and managing underlying conditions.


Common Infections: Common infections include respiratory infections, dental infections, and skin infections.

Prevention and Treatment: Regular veterinary care, vaccinations, and prompt treatment of infections are crucial.

Monitoring Senior Cat Health

Regular Check-ups: Regular vet visits are essential for early detection and management of health issues.

At-home Monitoring: Keep an eye on your cat’s behavior, appetite, and physical condition. Look for any changes and consult your vet if you notice anything unusual.

Red Flags: Sudden weight loss, changes in behavior, and persistent symptoms are red flags that require immediate veterinary attention.

Preventive Care for Senior Cats

Preventive care is crucial for keeping your senior cat healthy and happy. Here are some key areas to focus on:

Veterinary Visits:

  • Schedule Regular Exams: Increase the frequency of vet visits. Ideally, aim for biannual checkups (every 6 months) for senior cats.
  • Comprehensive Exams: These exams include a physical check-up, discussing any behavior changes you’ve noticed, and potential recommendations for bloodwork, urinalysis, or other screenings.

Diet and Weight Management:

  • Senior Cat Food: Switch to a diet formulated for senior cats. These diets are often lower in calories and easier to digest for older felines.
  • Monitor Weight: Senior cats are prone to weight gain, which can worsen health issues. Regularly monitor their weight and adjust food portions as needed.

Home Environment:

  • Accessibility Adjustments: As cats age, they may become less mobile. Make adjustments like placing ramps near furniture and having litter boxes on every floor for easier access.
  • Enrichment: Provide mental stimulation with puzzle feeders, scratching posts, and catnip toys. This keeps them engaged and helps prevent boredom.

Other Preventative Measures:

  • Parasite Prevention: Continue regular parasite prevention medication to guard against fleas, ticks, and worms.
  • Dental Care: Dental disease is common in older cats. Discuss dental cleaning options with your veterinarian.
  • Vaccinations: Consult your vet about necessary vaccinations for your senior cat. They may need some core vaccines like rabies, but the frequency might decrease.

Home Adaptations for Senior Cats

Making the home senior-friendly includes providing easy access to food, water, litter boxes, and comfortable resting places. Consider ramps or steps to help with mobility.

Our feline friends can get a bit stiff and slow down as they age. Luckily, there are some simple adjustments you can make around your house to keep your senior cat feeling safe, secure, and independent. Here are some home adaptation ideas:

Making Favorite Spots Accessible:

  • Ramps and Steps: Install ramps or sturdy boxes to help your cat reach previously accessible places like high beds, window sills, or scratching posts.
  • Lowered Perches: Consider placing cat shelves or perches at lower levels for easier lounging.

Litter Box Accessibility and Comfort:

  • Multiple Boxes: Provide multiple litter boxes, especially on different floors of your home, to avoid long walks.
  • Larger Boxes: Larger litter boxes can be more comfortable for senior cats with mobility limitations.
  • Lower Entry Points: Use a shallow litter box with a lower entry point for easier access. You can even cut an entryway on the side of a regular box.

Food and Water Stations:

  • Elevated Bowls: Raised food and water bowls can improve posture and make eating and drinking more comfortable for arthritic cats.
  • Non-Slip Mats: Place non-slip mats under food and water bowls to prevent them from sliding around and causing spills.

Safety and Security:

  • Non-Slip Surfaces: Add rugs or mats on slippery floors, especially near the litter box and water bowls, to prevent slips and falls.
  • Secure Windows and Balconies: Ensure windows and balconies are securely screened or closed to prevent adventurous escapes.

Comfort and Enrichment:

  • Soft Bedding: Provide plenty of soft bedding in various locations around the house, including memory foam options for joint support.
  • Warmth: Older cats often feel the cold more. Consider placing heating pads (set on low) under their favorite beds or perches.
  • Interactive Toys: Provide puzzle feeders, food dispensing toys, or catnip toys to keep them mentally stimulated and engaged.
