Entering the senior years

Cats are generally considered senior around age ten to eleven, though individual aging varies significantly. Some cats show few changes at twelve, while others develop noticeable decline by nine. Size is less predictive in cats than in dogs, so clinical signs matter more than calendar age.

Increased veterinary monitoring

Semi-annual exams become essential. Comprehensive bloodwork, urinalysis, blood pressure measurement, and thyroid screening catch the conditions most common in senior cats: chronic kidney disease, hyperthyroidism, diabetes mellitus, and hypertension.

Kidney disease is particularly prevalent, affecting a significant percentage of cats over twelve. Early detection through regular bloodwork and urine specific gravity testing allows dietary and medical management that can extend comfortable life by years.

Kidney health strategies

Increased water intake supports kidney filtration. Wet food, water fountains, multiple water stations, and adding water or low-sodium broth to food all encourage hydration. Kidney-supportive diets with controlled phosphorus and moderate protein may be recommended once kidney values begin to shift.

Never restrict protein without veterinary guidance. Senior cats with normal kidney function need adequate protein to prevent muscle wasting.

Hyperthyroidism awareness

An overactive thyroid gland causes weight loss despite increased appetite, restlessness, vomiting, and increased thirst. It is one of the most treatable conditions in senior cats when caught early. Treatment options include daily medication, radioactive iodine therapy, dietary management, and surgery.

Comfort and accessibility

Arthritis is common but underdiagnosed in cats because they rarely limp. Instead, arthritic cats stop jumping to favorite perches, hesitate at stairs, or groom less thoroughly. Provide steps or ramps to elevated surfaces, low-entry litter boxes, and warm bedding in quiet locations.

Nightlights help cats with declining vision navigate at night. Keep furniture in consistent positions, as spatial memory compensates for sensory loss.

Dental considerations

Dental disease continues to accumulate. Tooth resorption, a painful condition unique to cats, increases in prevalence with age. Regular oral exams and dental cleanings manage pain that cats are biologically driven to hide.

Cognitive changes

Feline cognitive dysfunction manifests as nighttime vocalization, disorientation, altered sleep-wake cycles, and changes in social interaction. Environmental enrichment, consistent routines, and veterinary-guided interventions can moderate symptoms.

Quality of life assessment

Track daily indicators: appetite, mobility, grooming, social engagement, and pain signals. Gradual decline is expected, but sudden changes warrant prompt veterinary attention. Your veterinarian can help establish quality-of-life metrics to guide care decisions as needs evolve.
