Senior Cat Health Screening: Essential Tests After Age 7
Senior cats (7+ years) are at higher risk for hyperthyroidism, kidney disease, diabetes, and dental disease. Regular screening every 6 months can detect problems early when treatment is most effective. Early detection extends both lifespan and quality of life.
Your cat may look and act the same at 10 as they did at 5, but their body is aging. Regular health screening for senior cats can catch serious diseases early, often before symptoms appear, giving you more treatment options and better outcomes.
When Is a Cat Considered Senior?
Life Stage Classifications
| Life Stage | Age Range | Screening Frequency |
|---|---|---|
| Adult | 1-7 years | Annual wellness exams |
| Senior | 7-10 years | Every 6-12 months |
| Geriatric | 11+ years | Every 3-6 months |
Indoor cats typically live 13-17 years, meaning senior and geriatric years represent 40-60% of their total lifespan. This makes preventive care crucial for maintaining quality of life during these golden years.
Common Age-Related Health Issues
Most Prevalent Senior Cat Conditions
- • Hyperthyroidism — Affects 10% of cats over 10 years old. Learn more about hyperthyroidism symptoms and T4 testing
- • Chronic Kidney Disease — Affects 30% of cats over 15. See our guide to CKD stages and management
- • Diabetes — Increasing in prevalence, especially in overweight cats. Read about diabetes management and glucose monitoring
- • Dental Disease — Affects 70% of cats over 3 years, worsens with age
- • Arthritis — May affect 90% of cats over 12, often underdiagnosed
- • High Blood Pressure — Often secondary to kidney disease or hyperthyroidism
Why Early Detection Matters
Many senior cat diseases develop gradually, and cats are masters at hiding illness. By the time symptoms appear, diseases may be advanced and harder to treat.
Benefits of early detection: More treatment options, better outcomes, lower costs, and maintained quality of life for longer periods.
Essential Blood Tests for Senior Cats
Complete Blood Count (CBC)
Evaluates red blood cells, white blood cells, and platelets. Can detect anemia, infections, and blood cancers common in older cats.
For detailed interpretation, see our complete guide to cat CBC results.
Chemistry Panel
Kidney Function Tests: BUN, creatinine, and SDMA detect kidney disease. Learn more about interpreting kidney values in cats.
Liver Function Tests: ALT, ALP, AST, and GGT assess liver health. Our liver enzymes guide explains what elevated values mean.
Other Important Values: Glucose (diabetes screening), electrolytes, and total protein levels.
Thyroid Testing (T4)
Essential for cats over 8 years old. Hyperthyroidism is extremely common and easily treatable when caught early.
Normal T4: 0.8-4.7 μg/dL. Values above 4.7 typically indicate hyperthyroidism requiring treatment with methimazole or other therapies.
Comprehensive Senior Cat Screening Schedule
Ages 7-10 Years (Senior)
Every 6-12 Months:
- • Complete physical examination
- • Body weight and body condition scoring
- • Blood pressure measurement
- • Complete blood count (CBC)
- • Chemistry panel including kidney and liver values
- • Thyroid testing (T4)
- • Urinalysis
Annually:
- • Dental examination and cleaning if needed
- • Thoracic radiographs (chest X-rays)
- • Abdominal ultrasound if indicated
Ages 11+ Years (Geriatric)
Every 3-6 Months:
- • All tests listed above for senior cats
- • Increased frequency allows earlier detection
- • More frequent monitoring of chronic conditions
Additional Considerations:
- • Cardiac evaluation if heart murmur detected
- • Arthritis assessment and pain management
- • Cognitive function evaluation
- • Quality of life assessments

Blood Pressure Monitoring
High blood pressure (hypertension) is common in senior cats, often secondary to kidney disease or hyperthyroidism.
Normal systolic pressure: 110-160 mmHg. Values above 160 mmHg require treatment to prevent organ damage, especially to the eyes and kidneys.
Imaging Studies
Thoracic Radiographs: Screen for heart disease, lung tumors, and other chest abnormalities.
Abdominal Ultrasound: Evaluates kidney architecture, liver structure, and screens for masses.
Echocardiogram: Detailed heart evaluation if murmurs or arrhythmias are detected.
Specialized Testing
- • Fructosamine: Long-term glucose control assessment for diabetic cats
- • Symmetric dimethylarginine (SDMA): Early kidney disease detection
- • Free T4: More sensitive thyroid testing for borderline cases
- • Troponin-I: Heart muscle damage assessment
Signs to Watch for at Home
Subtle Changes That Matter
- • Weight changes: Even 1-2 pounds is significant for cats
- • Appetite changes: Increased or decreased food intake
- • Water consumption: Drinking more or less than usual
- • Litter box habits: Frequency or difficulty urinating
- • Activity level: Less jumping, climbing, or playing
- • Grooming habits: Poor coat condition or over-grooming
When to Schedule Emergency Evaluation
- • Difficulty breathing — Can indicate heart or lung disease
- • Inability to urinate — Medical emergency requiring immediate care
- • Severe lethargy — Dramatic behavior changes
- • Loss of appetite for >24 hours — Can lead to hepatic lipidosis
- • Vomiting or diarrhea — Especially if persistent
Optimizing Senior Cat Care
Nutrition Considerations
- • Higher protein: Senior cats often need more protein to maintain muscle mass
- • Easy digestion: Smaller, more frequent meals may be better tolerated
- • Joint support: Omega-3 fatty acids and glucosamine supplements
- • Kidney support: Therapeutic diets if kidney disease is present
- • Weight management: Obesity worsens arthritis and diabetes risk
Environmental Modifications
- • Easy access: Ramps or steps to favorite sleeping spots
- • Litter box accessibility: Lower sides, non-slip mats
- • Comfortable bedding: Orthopedic beds for arthritic cats
- • Temperature control: Senior cats may need extra warmth
- • Mental stimulation: Puzzle feeders and interactive toys
Pain Management
Arthritis is extremely common but often unrecognized in senior cats. Signs include decreased activity, reluctance to jump, and changes in litter box use.
Pain management options include prescription medications, supplements, acupuncture, and environmental modifications. Work with your vet to develop a comprehensive pain management plan.
Cost Considerations
Typical Senior Screening Costs
| Test/Service | Typical Cost | Frequency |
|---|---|---|
| Physical exam | $50-100 | Every 6 months |
| Basic blood panel | $150-250 | Every 6-12 months |
| Comprehensive panel + T4 | $200-350 | Every 6-12 months |
| Blood pressure check | $25-50 | Every visit |
| Urinalysis | $30-60 | Every 6-12 months |
Value of Preventive Care
While regular screening requires an investment, early detection of diseases like hyperthyroidism, diabetes, or kidney disease can save thousands in emergency costs and extend your cat's quality life significantly.
Many pet insurance plans cover routine senior care, and some veterinary clinics offer wellness packages that can reduce overall costs.
