Cats are living longer than ever due to advances in veterinary medicine, nutrition, and indoor lifestyle management. The "senior" cat is typically defined as over 10 years old, with "geriatric" cats over 15 years. Understanding the welfare needs of ageing cats enables owners to provide excellent quality of life through their later years.
Normal Changes of Ageing
Distinguishing normal ageing changes from pathological disease is the first welfare challenge in senior cat management:
- Reduced activity and sleep schedule changes — normal, but should not be confused with pain-related immobility
- Reduced muscle mass (sarcopenia) — normal but accelerated by disease, pain, or inadequate protein intake
- Reduced sensory acuity (hearing and vision decline) — affects navigation and startling; environmental adjustments help
- Coat care reduction — cats groom less effectively with age due to stiffness; regular brushing maintains coat health
- Cognitive changes — feline cognitive dysfunction syndrome (CDS) affects up to 50% of cats over 15
Proactive Health Monitoring
Biannual veterinary examinations (every 6 months rather than annually) are recommended for senior cats — disease progression can be rapid, and early detection dramatically improves welfare outcomes. Key screening tests:
- Blood pressure measurement — hypertension is common in older cats and causes retinal damage, renal disease, and neurological signs
- Thyroid hormone (T4) — hyperthyroidism affects approximately 10% of cats over 10
- Renal panel (creatinine, SDMA, urine specific gravity) — CKD prevalence increases steeply with age
- Blood glucose/urine glucose — diabetes prevalence increases with age, particularly in neutered males
Pain Management in Older Cats
Degenerative joint disease (osteoarthritis) affects over 90% of cats over 12 years on X-ray, though clinical signs are often subtle. Owners rarely recognise feline arthritis — cats don't limp obviously but instead show reduced jumping, hesitation on stairs, and reduced grooming of hindquarters. Meloxicam (low dose, licensed long-term in cats) and newer anti-NGF therapies (frunevetmab/Solensia — monoclonal antibody) significantly improve welfare in arthritic cats.
Nutrition
Senior cats benefit from diets with increased high-quality protein (to maintain muscle mass) and modified phosphorus levels (to reduce renal load). Palatability is important as appetite often declines with age — warming food, adding water, and offering variety maintains food intake. Obesity in younger cats predisposes to diabetes and joint disease; many senior cats lose weight inappropriately, requiring calorie-dense, palatable food.
Environmental Modifications
Environmental adaptations significantly improve welfare for older cats:
- Ramps or steps providing access to favourite elevated resting spots
- Low-sided litter trays for cats with reduced mobility or incontinence
- Multiple warm sleeping areas with easy access
- Predictable, quiet routine — reduces anxiety in cats with cognitive decline
- Nightlights — assist cats with reduced vision navigating at night
