Senior Cat Care: Vet Checks, Diet and Comfort for Older Cats
Older cats hide illness well. Regular vet visits, attention to small changes and a few simple home adjustments help them stay comfortable for longer.
Cats are generally considered senior from about 10 years of age, according to the 2021 AAHA/AAFP Feline Life Stage Guidelines, which also recommend that senior cats see a veterinarian at least every six months, and more often if they have a chronic condition. Older cats are good at hiding illness, so the most useful things you can do are keep up with checkups, watch for small changes in weight, thirst, appetite, litter box habits and mobility, and make your home easier to navigate.
This guide covers the basics. Your veterinarian is the best person to tailor a plan for your cat, so contact them with any questions or changes you notice.
Why regular checkups matter more with age
Many conditions that are common in older cats develop slowly and may not show obvious signs early on. For example, the Cornell Feline Health Center notes that chronic kidney disease affects up to 40% of cats over 10 and up to 80% of cats over 15. Hyperthyroidism, dental disease, arthritis, diabetes, high blood pressure and cancer are other conditions vets look for in older cats.
At a senior checkup, your vet may:
- Weigh your cat and assess body and muscle condition
- Examine the mouth, teeth, eyes, heart, joints and abdomen
- Recommend blood and urine tests, including kidney and thyroid values
- Check blood pressure
- Review diet, behavior, litter box habits and any medications
Only your vet can interpret results and decide whether treatment is needed.
Changes to watch for at home
| What you might notice | Why it is worth mentioning to your vet |
|---|---|
| Drinking more, peeing more, larger litter clumps | Can be linked to several conditions, including kidney disease, diabetes and hyperthyroidism |
| Weight loss, even with a good appetite | Gradual weight loss is easy to miss; regular weighing helps |
| Eating less, dropping food, chewing on one side | May indicate dental pain or other illness |
| Not jumping up, hesitating on stairs, stiffness | Often a sign of arthritis, which is common and under-recognized in cats |
| Accidents outside the litter box | Can be medical or due to difficulty getting into the box |
| Unkempt or matted coat | Older cats may groom less because of pain or stiffness |
| More vocal at night, confusion, getting “lost” | Can be associated with age-related cognitive changes or other conditions |
| Vomiting more often | Should not be dismissed as hairballs in an older cat; see why is my cat throwing up |
Keeping a simple log of weight (if you have a scale), appetite and litter box changes makes vet visits more useful. Our guide to signs your cat is in pain describes subtle pain behaviors in more detail.
See a vet right away if your senior cat
- Stops eating for more than about a day
- Has difficulty breathing or breathes with an open mouth
- Strains in the litter box without producing urine
- Vomits repeatedly, or has bloody vomit or diarrhea
- Suddenly cannot use its back legs, or collapses
- Seems very weak, lethargic or disoriented
Diet for older cats
There is no single “senior diet” that suits every older cat. Some older cats gain weight because they are less active; others lose weight and muscle and need more calories or more digestible food. Some medical conditions benefit from specific therapeutic diets that should only be used under veterinary guidance.
- Feed a complete and balanced food that suits your cat’s life stage and health, as recommended by your vet. Our article on cat food for senior cats explains the options.
- Encourage water intake: offer several water bowls, a water fountain, or some wet food if your vet agrees.
- Make any diet change gradually over a week or more.
- Do not change your cat’s diet to manage a medical condition without your vet’s advice.
Making your home senior-friendly
- Litter boxes with low sides on every floor, in easy-to-reach spots. A storage tray with a low cut-out entry works well.
- Steps or ramps up to favorite spots such as the sofa, bed or window ledge.
- Warm, padded beds in quiet, draft-free places; many older cats love warmth.
- Food and water on the main level, so your cat does not have to climb or jump to reach them.
- Non-slip surfaces, such as rugs or mats, on slippery floors.
- Night lights can help cats with declining vision find their way.
Grooming, claws and teeth
Senior cats may groom less and their claws can become thick and overgrown, sometimes growing into the paw pad. Check claws regularly and trim as needed; see how to trim cat claws. Gentle brushing helps with coat care and gives you a chance to feel for lumps. Ask your vet about dental care, because dental disease is common and can be painful.
Keeping an older cat engaged
Older cats still benefit from play and mental stimulation, just at a gentler pace: short wand-toy sessions, food puzzles, a sunny window perch and time with you. Keep routines predictable, as many older cats find change stressful.
Comfort and quality of life
As cats age, conversations with your vet may turn to managing chronic conditions and keeping your cat comfortable. Your vet can help you assess quality of life, such as appetite, mobility, grooming, interest in surroundings and pain, and talk through options when the time comes. These decisions are personal, and a good vet will support you through them.
Bottom line
From about 10 years old, plan vet checks at least twice a year, watch closely for changes in weight, thirst, appetite, mobility and litter box habits, and adapt your home with low-entry litter boxes, ramps and warm beds. Early detection and comfort-focused care make a real difference for older cats.
FAQ
At what age is a cat considered senior?
The 2021 AAHA/AAFP Feline Life Stage Guidelines define senior as 10 years and older. Individual cats age differently, so your vet will assess your cat at each visit.
Do senior cats need blood tests every year?
Many vets recommend regular blood and urine testing in older cats to catch problems early. How often depends on your cat’s health; ask your vet.
Is it normal for an old cat to sleep more?
Older cats often rest more. But a sudden increase in sleep, or sleeping in unusual places, can be a sign of pain or illness and is worth mentioning to your vet.
My older cat is losing weight but eating well. Should I worry?
Weight loss with a good appetite should be checked by your vet, as it can be linked to medical conditions that are more common in older cats.
