Cats are typically considered senior around 11 years old, though this varies by breed and individual health. In this article, "senior" is used broadly to cover mature, senior, and geriatric stages. These life-stage definitions align with general veterinary guidelines (AAHA/AAFP). Many vets use these rough categories:

  • Mature: about 7–10 years. Subtle slowing, weight shifts, and less jumping may appear.
  • Senior: about 11–14 years. Age-related changes become more visible and worth tracking.
  • Geriatric: about 15 years and older. Closer monitoring and more frequent vet visits help.

What changes first? Watch for these early, common signs:

  • Less jumping onto counters or furniture.
  • Longer naps and less play.
  • Thinner muscles along the spine and hind legs.
  • Slower grooming, sometimes with a duller coat.
  • Small shifts in appetite, water intake, or litter box habits.

Start a simple log now. Note weight, appetite, water intake, litter box use, and activity. For healthy senior cats, weigh them monthly on an infant scale (available at most pharmacies or online). If your cat has a diagnosed condition like kidney disease or hyperthyroidism, weigh them weekly using the same scale. These baselines make it easier to spot real changes and give your vet useful details at each visit.

Arthritis and Mobility Loss: A Room-by-Room Checklist to Make Movement Easier

Arthritis often shows up as small changes: a cat who stops jumping on the bed, hesitates at stairs, or sits instead of crouching to eat. Walk through your home room by room and fix the friction points. Ask your vet about pain assessment tools and management options, including medications and joint supplements, to ensure your cat is comfortable.

  • Living room: Add a low step or sturdy ottoman beside the sofa so your cat can climb in stages. Keep favorite beds on the floor, not on high shelves.
  • Stairs: Decide if your cat can safely navigate stairs. If they struggle, block off upper floors entirely. If they still use the stairs, place a ramp over the steps. Do not mix these strategies; choose one approach based on your cat's ability.
  • Kitchen and feeding area: Raise food and water bowls slightly (about 1–2 inches) or keep them at ground level, depending on what allows your cat to eat without straining their neck. Use non-slip mats under bowls to prevent sliding.
  • Litter box: Choose a box with low sides, about 2–3 inches high, and place it on the same floor where your cat spends most of the day. If you have blocked off upper floors, do not place boxes there.
  • Bedroom: Offer a heated pad or orthopedic bed. Place it away from drafts and near a wall for support.

Check these spots weekly. If your cat avoids a room or stops using a box, note it and report the change at your next vet visit.

Kidney and Urinary Issues: Tracking Water, Litter Box, and Weight at Home

Kidney and urinary problems are common in senior cats, and early changes are easy to miss. A simple home routine catches them sooner. Track three things: water intake, litter box output (urine clumps and stool), and weight.

For water, note how often you refill the bowl. Veterinary nutrition guidelines suggest cats typically drink roughly 0.75 to 1.5 ounces of water per pound of body weight daily. For example, a 10-pound cat usually needs about 7.5 to 15 ounces per day, though cats eating mostly wet food will drink less. A sudden increase in drinking is a red flag. Consider offering a running water source, such as a pet fountain, if your cat rarely drinks.

For the litter box, scoop at the same time daily and note:

  • Clump size and number: more or larger clumps can mean increased urination.
  • Urine color and smell: watch for pink, red, or strong odor.
  • Straining, crying, or frequent small trips.
  • Accidents outside the box.

Emergency Warning: If your cat is male and is straining to urinate with little or no output, this is a life-threatening emergency. Seek immediate veterinary care; urinary blockages can be fatal within 24–48 hours.

Weigh your cat according to the schedule above. A loss of roughly 5% of body weight over a few weeks warrants a vet call. Log all three in one notebook or app, and bring it to every appointment.

Dental Disease and Appetite Loss: A Weekly Mouth-and-Mealtime Check

Bad teeth often show up first as a cat who chews on one side, drops food, or eats less. Once a week, do a quick mouth-and-mealtime check. It takes about two minutes and catches problems early.

Mouth check:

  • Lift the lip on each side. Look for red gums, brown tartar, or broken teeth.
  • Sniff the breath. Mild odor is common; strong or foul smell is not.
  • Watch for drooling, pawing at the mouth, or flinching when you touch the jaw.
  • Note any loose or missing teeth.

Mealtime check:

  • Record how much you offer and how much is left. A drop of roughly a quarter of the usual amount is worth noting.
  • Watch the first few bites. Side-chewing, head tilting, or food falling out are red flags.
  • Check for weight change monthly on the same scale (or weekly if advised by your vet).
  • Log any vomiting, drooling while eating, or refusal of hard food.
  • Write each result in a simple log. Bring it to the vet. Dental pain is common in senior cats and often hidden. A cat that stops eating for more than about a day needs a vet call, not a wait-and-see. When discussing dental work, ask your vet about pre-anesthetic blood tests and heart assessments to minimize anesthesia risks for older cats.

    Hyperthyroidism, Diabetes, and Cognitive Changes: Signs to Log and Report

    Three conditions deserve a simple log. Keep one notebook or phone note for all of them. Bring it to every vet visit.

    Hyperthyroidism: Watch for weight loss despite a good appetite, increased drinking, restlessness, and a scruffy coat. Treatment options may include medication, prescription diet, or radioactive iodine therapy—your vet will recommend based on your cat's condition. Weigh your cat weekly on the same scale. Log the number and the date.

    Diabetes: Watch for heavy drinking, large urine clumps, and appetite swings. Note how much water you refill each day and how many clumps you scoop. A cat that suddenly stops eating needs a vet call the same day.

    Cognitive changes: Watch for yowling at night, staring at walls, confusion about familiar rooms, and accidents outside the litter box. Note that night yowling can also signal pain, hypertension, or hyperthyroidism—ask your vet to rule these out before assuming cognitive decline. Log when each happens and how often.

    Report any of these signs promptly:

    • Weight change of roughly 2–3% between weekly weigh-ins, or 5% over a few weeks
    • Water intake that clearly rises and stays high for several days
    • Sudden appetite loss lasting more than about a day
    • New nighttime vocalizing or disorientation

    Write down what you saw, when it started, and how often it happens. Patterns help your vet more than single events.

    Your Senior Cat Vet Plan: What to Ask, How Often to Go, and What to Track

    The American Association of Feline Practitioners (AAFP) recommends at least biannual exams for cats over 10–11 years old. Ask your vet to set a checkup schedule based on your cat's age and test results. Cats with a diagnosed condition may need rechecks more often, typically every one to three months. Bring a simple log to every visit.

    What to Track at Home

    • Weight: weigh monthly for healthy seniors, or weekly for those with chronic conditions, using an infant scale.
    • Food and water intake: note changes in amount or appetite.
    • Litter box output: record urine clumps and stool, and any accidents outside the box.
    • Behavior: sleep, grooming, activity, confusion, night yowling.
    • Medications: doses, times, and any side effects.

    What to Ask Your Vet

    1. Which baseline blood and urine tests should we run, and how often?
    2. What weight and appetite changes should trigger a call?
    3. Are pain checks and dental exams part of every visit?
    4. What is the plan if test results change?

    Keep one folder for records. Review the log before each visit, and call between visits if something changes quickly.

    • Call the Vet Same Day: No appetite for >24 hours, vomiting, diarrhea, or significant lethargy.
    • Emergency Room Immediately: Straining to urinate with no output (especially in males), difficulty breathing, inability to stand, or collapse.
