How to Care for a Senior Cat

Last updated May 24, 2026 · 8 min read

Cats over 10 are officially senior, and over 15 they’re geriatric. The care shifts at each stage aren’t complicated, but they’re different from what worked in middle age. Done well, senior cat care can add quality years. Not just survival, but the kind of years a cat actually enjoys.

Vet visits: twice a year, with bloodwork

The most important shift for senior cats is the cadence of vet visits. The 2021 AAHA/AAFP guidelines treat cats 10 and older as senior, and twice-yearly wellness visits are the standard recommendation from that point (many vets encourage them from the mature stage, around 7). The reason: cats age roughly four human years per calendar year at this stage, and chronic diseases progress faster than annual snapshots can catch.

Each visit should include weight, body condition score, oral exam, palpation, and a senior bloodwork panel with urinalysis at least annually. The panel costs $150–$300 and catches the three most common senior cat diseases (kidney disease, hyperthyroidism, and diabetes) while they’re still easy to manage.

Nutrition: protein-forward, calorie-controlled, phosphorus-aware

Senior cats need diets that protect kidney function while preserving lean muscle mass. The two big principles:

• Adequate, high-quality protein. Old advice was to restrict protein in older cats. Modern research has reversed that. Healthy senior cats need more protein than adult cats, not less, to maintain muscle. Protein is restricted only in confirmed advanced kidney disease, and even then, modestly.
• Controlled phosphorus. Most senior-formula foods reduce phosphorus, which slows kidney decline. This is one of the most evidence-supported dietary moves for older cats.
• Calorie awareness. Activity drops, so calorie needs do too, until kidney disease or hyperthyroidism shifts the picture again. Monthly weight checks beat eyeballing.

Hydration: this matters more than most owners realize

Cats are descended from desert ancestors and drink poorly even when healthy. Aging cats with declining kidney function need more water, but often drink less. The result is chronic mild dehydration that accelerates kidney decline.

Three high-leverage moves:

• Add wet food. Canned food is 70–80% water; kibble is about 10%. Even partial transition to wet adds meaningful hydration.
• Multiple water stations. Place bowls in several rooms, away from the food bowl (cats often prefer water that’s not next to food).
• Try a fountain. Many cats drink twice as much from running water. Ceramic fountains are quieter than plastic and easier to clean.

Environment: small changes, big quality-of-life gains

Senior cats live better when the environment accommodates a less agile body. The changes are inexpensive and high-impact:

• Lower-sided litter boxes. A storage container with one side cut down works perfectly. Stiff hips and arthritic joints make standard high-sided boxes painful to enter.
• More litter boxes. The standard rule is one per cat plus one extra; for senior cats, add another on each floor of the house.
• Steps or ramps to favorite spots; beds, windowsills, couches. Pet stairs run $30–$60 and prevent jump injuries.
• Warm, soft sleeping spots away from drafts. Aging cats lose body heat faster and arthritis flares in cold weather.
• Non-slip surfaces on tile and hardwood floors near food, water, and litter. Slips on smooth floors are a leading source of senior cat injuries.
• Night lights. Senior cats with weaker vision navigate dark hallways better with low-level ambient light.

Joint care: assume it’s an issue

Feline arthritis is so common past age 10 that the right default is to assume your cat has some degree of it and act accordingly. Specific moves that help:

• Joint supplements. Glucosamine/chondroitin and omega-3 (EPA/DHA from fish oil) have the best supporting evidence for cats.
• Veterinary anti-inflammatories when appropriate. The newer monoclonal antibody (frunevetmab/Solensia) is a once-monthly injection developed specifically for feline arthritis and has changed senior cat care considerably.
• Gentle play. Brief, low-intensity sessions with wand toys preserve muscle around the joints. Sedentary senior cats lose function faster than active ones.
• Weight control. Every extra pound on an arthritic cat amplifies the problem. Lean senior cats move better.

Dental care

An estimated 70% of cats over age 3 have some degree of dental disease, and it gets worse with age. Untreated dental disease is associated with kidney and heart issues through chronic low-grade infection. The standard senior cat should have an oral exam at every visit and a professional dental cleaning under anesthesia when indicated. Usually every 2–3 years.

Anesthesia in older cats is safer than it used to be with modern protocols and pre-anesthetic bloodwork, and the benefit of cleaning up active dental disease typically outweighs the risk. Talk to your vet specifically about anesthetic safety for your individual cat rather than assuming “too old to anesthetize.”

Cognitive care

Feline cognitive dysfunction affects more than 50% of cats over 15. Signs include nighttime yowling, disorientation, broken litter box habits, and changes in social interaction. Practical management:

• Maintain consistent routines for feeding, play, and bedtime.
• Use diffusers (Feliway) to lower environmental stress.
• Add interactive play and food puzzles to keep the mind engaged.
• Talk to your vet about nutritional support (medium-chain triglycerides, antioxidants) and prescription options if needed.

End-of-life: how to recognize it

One of the hardest parts of having a senior cat is knowing when comfort care isn’t enough anymore. The framework many vets use is quality of life: is your cat still eating, still grooming at least somewhat, still seeking out interaction, still relieved of acute pain? When two or more of those reliably fail for more than a few days, the conversation shifts.

This is a conversation worth having with your vet earlier than you think you need it. Hospice care, in-home euthanasia, and pain management options have improved enormously in the past decade.

Putting it together

Senior cat care is mostly small, consistent moves: twice-yearly vet visits, blood and urine panels, weight tracking, more water, joint support, lower litter boxes, soft beds, and patience. None of it is dramatic. Done consistently over years, the difference is measurable in both lifespan and how good those years actually feel.
