Senior Cat Care
As cats age, their needs change in ways that are easy to miss at home. This guide explains how to care for a senior cat, what health problems become more common with age, what symptoms to watch for, and when it is time to call your veterinarian.
What counts as a senior cat?
Most veterinary life-stage resources place cats into older-age categories before many owners expect. Merck notes that senior cats are generally over 8 to 9 years old, and older cats should usually be seen by a veterinarian twice yearly or more often. Feline life-stage guidance from the American Association of Feline Practitioners also separates mature adult and senior stages, reflecting the fact that age-related disease risk rises before a cat appears visibly elderly. In practical terms, if your cat is around 10 years or older, it is smart to think proactively about screening, comfort, mobility, dental care, and behavior changes rather than waiting for obvious illness. This is also a good time to review related topics such as /guides/cat-wellness-exam, /symptoms/weight-loss-in-cats, /symptoms/increased-thirst-in-cats, /symptoms/vomiting-in-cats, and /conditions/chronic-kidney-disease-in-cats.
Merck says senior cats over 8 to 9 years old should generally visit the vet twice a year or more often.
Merck reports that approximately 60% to 90% of older cats have osteoarthritis.
Merck’s cat owner guidance lists senior cats as roughly 10 to 14 years, with geriatric cats 14 years and older.
AVMA client education notes that cancer is the cause of death in about a third of cats over 10 years old.
Why preventive care matters more in older cats
Cats are very good at hiding illness, and age-related disease often develops gradually. Authoritative veterinary sources recommend more frequent senior wellness visits because early changes may only show up on physical exam, blood work, urinalysis, blood pressure checks, or weight tracking. VCA notes common components of senior screening can include a complete blood count, chemistry panel, urinalysis, thyroid testing, and blood pressure assessment. Preventive visits can help detect chronic kidney disease, hyperthyroidism, hypertension, dental disease, arthritis, diabetes, and heart disease sooner. If your cat already has a diagnosis, regular follow-up helps your veterinarian adjust the plan before small changes become emergencies. Owners often benefit from reading related pages like /conditions/hyperthyroidism-in-cats, /conditions/diabetes-in-cats, /conditions/high-blood-pressure-in-cats, /conditions/heart-disease-in-cats, and /guides/how-to-read-cat-bloodwork.
A practical senior cat care checklist
Schedule checkups twice yearly
Even if your cat seems fine, older cats benefit from routine exams and lab screening.
Track weight and appetite
Unplanned weight loss, muscle loss, or a sudden increase or decrease in appetite deserves attention.
Watch water intake and litter box habits
Increased thirst, larger urine clumps, constipation, or straining can be early signs of disease.
Prioritize dental health
Bad breath, drooling, pawing at the mouth, and reluctance to eat may point to dental pain.
Support mobility
Add steps, low-entry litter boxes, warm sleeping areas, and easy access to food and water.
Monitor behavior changes
Confusion, nighttime vocalizing, hiding, house-soiling, and irritability can reflect pain or illness.
Keep parasite prevention current
Indoor cats still need individualized parasite prevention and routine veterinary guidance.
Review nutrition regularly
Diet should match your cat’s age, body condition, dental status, and any medical diagnoses.
Common health problems in senior cats
The conditions veterinarians look for most often in older cats include chronic kidney disease, hyperthyroidism, hypertension, osteoarthritis, dental disease, diabetes, heart disease, and cancer. Merck notes that older cats are more likely to get sick, and that routine blood tests may help identify chronic illness early. Chronic kidney disease can cause increased thirst, increased urination, weight loss, and poor appetite. Hyperthyroidism often causes weight loss despite a good appetite, restlessness, vomiting, or diarrhea. Arthritis may show up as reluctance to jump, stiffness, hiding, or reduced grooming instead of obvious limping. Dental disease can lead to bad breath, oral pain, drooling, and reduced interest in food. For deeper reading, owners often search for /conditions/arthritis-in-cats, /conditions/dental-disease-in-cats, /conditions/cancer-in-cats, /symptoms/bad-breath-in-cats, /symptoms/limping-in-cats, and /symptoms/constipation-in-cats.
| Feature | May be seen with aging | Why it still matters | What to do |
|---|---|---|---|
| Sleeping more | Older cats may rest more and play less. | Sudden lethargy, weakness, or hiding can indicate illness, pain, anemia, heart disease, or metabolic disease. | Book a vet visit if the change is new, progressive, or paired with appetite or breathing changes. |
| Less jumping | Reduced agility can happen with age. | Arthritis is very common in older cats and often goes unnoticed because cats hide pain. | Call your vet to discuss a mobility exam and home modifications. |
| Weight loss | Mild muscle loss can occur with age. | Weight loss can also signal hyperthyroidism, kidney disease, diabetes, dental pain, GI disease, or cancer. | Any unexplained weight loss should prompt a veterinary appointment. |
| Behavior changes | Some older cats become less social or more vocal. | Pain, hypertension, hyperthyroidism, kidney disease, sensory decline, or cognitive dysfunction may be involved. | Call your vet, especially if the change is sudden or paired with nighttime pacing, confusion, or litter box issues. |
| Messier coat | Senior cats may groom less effectively. | A poor coat may reflect arthritis, obesity, dental pain, kidney disease, or other illness. | Schedule an exam if grooming declines or mats start forming. |
| Bad breath | It is common in cats with dental disease. | Bad breath is not normal and often means gingivitis, periodontitis, tooth resorption, or other oral disease. | Arrange a dental evaluation with your veterinarian. |
Symptoms owners should never ignore
Call your veterinarian promptly if your senior cat has weight loss, reduced appetite, vomiting, diarrhea, increased thirst, larger urine clumps, constipation, straining to urinate, bad breath, drooling, weakness, changes in jumping, new aggression, or confusion. Merck emphasizes that common signs of illness in cats can be subtle, and VCA notes that careful history-taking often identifies changes owners did not initially realize were important. Immediate assessment is especially important for trouble breathing, collapse, inability to urinate, sudden blindness, repeated vomiting, severe weakness, or any rapid change in mentation. Useful companion pages include /symptoms/not-eating-in-cats, /symptoms/diarrhea-in-cats, /symptoms/straining-to-urinate-in-cats, /symptoms/labored-breathing-in-cats, /symptoms/confusion-in-cats, and /symptoms/drooling-in-cats.

Nutrition, hydration, and body condition in older cats
There is no one-size-fits-all senior cat diet. Veterinary guidance focuses on maintaining ideal body condition, preserving muscle mass, supporting hydration, and tailoring food choices to any diagnosed disease. Older cats may lose weight because of chronic kidney disease, hyperthyroidism, dental pain, diabetes, gastrointestinal disease, or cancer. Others gain weight because pain or reduced activity limits movement. Your veterinarian may recommend different nutrition strategies depending on whether your cat is underweight, overweight, constipated, dehydrated, or living with a chronic condition. Fresh water access matters, and some cats do better with multiple water stations or a fountain. If your cat’s appetite changes, do not assume it is just age.

Pain, mobility, litter boxes, and home setup
Arthritis is extremely common in older cats, but the signs are often behavioral rather than dramatic. A senior cat with joint pain may stop jumping onto favorite furniture, hesitate on stairs, sleep downstairs, have a scruffy coat from reduced grooming, or avoid a high-sided litter box. Home adjustments can make a big difference: low-entry litter boxes, ramps or steps, nonslip rugs, warm beds, and food and water on every level of the home. Because cats can hide pain so effectively, owners should not start medications or supplements without veterinary guidance. If you suspect pain, call your vet for an exam and a safe treatment plan.

Behavior and cognitive changes in senior cats
Behavior changes in older cats should always be taken seriously because they may reflect pain, medical disease, sensory decline, stress, or cognitive dysfunction. Merck notes that aging in cats can affect behavior, and medical causes such as hypertension, renal disease, hyperthyroidism, and diabetes must be considered before behavior is dismissed as normal aging. Watch for increased vocalization, altered sleep-wake cycles, confusion, staring into space, house-soiling, changes in social interaction, or wandering at night. A behavior workup in a senior cat often starts with a physical exam, blood and urine testing, blood pressure measurement, and review of the home environment.
