TL;DR: Senior cats — generally those aged seven and older — need more frequent vet visits, a diet adjusted for lower calories and higher protein, and an environment that accounts for reduced mobility. They also need more attentive care from sitters when you travel, including twice-daily visits and a sitter who knows their specific health history. The earlier you adjust your care routine, the better your cat's quality of life in their later years.
Most cats do not announce that they are slowing down. One month they are jumping onto the kitchen counter without a second thought; a few months later they are eyeing it, reconsidering, and walking away. That shift can be easy to miss — and easy to misread as personality rather than age.
Cats are generally considered seniors from around seven years old, though many show no obvious signs until their mid-teens. The window between "no visible changes" and "clear health issues" is where the most useful care adjustments happen. This guide covers what those adjustments look like in practice — for daily life at home and for when you need to leave your senior cat in someone else's care.
What changes as cats age — and why it matters for their care
Senior cats experience a predictable set of physical changes, most of which affect how they eat, move, and process their environment. Muscle mass decreases even in cats who appear healthy. Joint stiffness becomes more common, and cats who once moved freely around the house may start favoring lower surfaces or spending more time in one spot. Kidney function often declines gradually with age, which has direct implications for diet and hydration. Dental disease, which affects the majority of cats over ten, can make eating painful enough to reduce food intake noticeably. Cognitive changes are also possible. Some senior cats develop feline cognitive dysfunction — a condition with similarities to dementia in humans — which can present as disorientation, changes in sleep patterns, or increased vocalization at night. This is worth knowing because it can look like behavioral problems when it is actually a health issue. None of this is cause for alarm. It is cause for paying closer attention and adjusting care before problems become acute.Vet visits: twice a year is the standard for a reason
A healthy adult cat can reasonably be seen by a vet once a year. For a senior cat, twice a year is the appropriate frequency. The interval matters because age-related conditions — kidney disease, hyperthyroidism, diabetes, hypertension — tend to develop gradually, and a six-month window catches changes that an annual check-up might miss entirely. At each visit, a senior wellness exam typically includes bloodwork and urinalysis to assess organ function, a blood pressure check, a dental assessment, and a weight check. Weight loss in senior cats is often the first sign of an underlying condition, and it can be subtle enough that you notice it only when you pick your cat up rather than by looking at them. Keep vaccinations and parasite prevention current. Some owners assume that indoor senior cats do not need ongoing parasite control, but this is not the case — indoor cats can still be exposed to fleas, and heartworm prevention remains relevant depending on your region.Diet and nutrition for senior cats
Senior cats need fewer overall calories than younger adults, but more protein relative to their body weight. This is because protein is needed to maintain muscle mass, which senior cats lose more readily. A diet that is low in calories but also low in protein accelerates muscle wasting — which is why standard "light" formulas are often not the right choice for older cats. Wet food becomes more relevant with age for two reasons. First, senior cats are more prone to kidney disease and benefit from higher moisture intake. Second, dental discomfort can make dry kibble harder to eat. A combination of wet and dry food works well for most senior cats, though the balance depends on your cat's specific health picture. Your vet is the right person to guide this, particularly if your cat has a diagnosed condition. Food portions matter more as metabolism slows. The online cat food portion calculator is a useful starting point for getting the daily amounts right, particularly if you are switching to a new food or adjusting for weight changes. Monitor water intake. A senior cat who is drinking noticeably more than usual — or noticeably less — is a cat worth bringing to the vet sooner rather than later.Comfort and mobility at home
Joint stiffness is common in senior cats and often goes undiagnosed because cats rarely limp in an obvious way. Instead, they stop jumping, start hesitating, or choose lower spots to sleep. These are behavioral changes with a physical cause, and addressing the environment is often the most immediate way to help. Practical adjustments: lower-sided litter boxes that are easy to step into, ramps or steps to help reach favored sleeping spots, and soft bedding placed at ground level or on low surfaces your cat can still reach comfortably. Food and water bowls at a slight elevation can help cats with neck stiffness eat and drink without discomfort. Keep the layout of your home consistent. Senior cats, particularly those with early cognitive changes, do better when familiar landmarks stay in place. Moving furniture around may seem minor, but for an older cat navigating partly by memory and partly by sight, it can be genuinely disorienting. 💤Grooming: what changes and what you can do
Many senior cats groom less effectively than they did when younger, either because reaching certain spots is physically harder or because they are simply less motivated. The practical result is matting, a duller coat, and potentially skin issues that go unnoticed under the fur. Regular brushing — a few times a week for shorthairs, daily for longhairs — prevents matting and gives you a chance to check for lumps, sores, or anything unusual on the skin. Nail trimming becomes more important with age. Senior cats are often less active, which means nails do not wear down naturally the way they do in younger cats. Overgrown nails can curve and catch, or cause discomfort when walking. The guides on how to trim your cat's nails and trimming nails on a resistant cat cover the technique for both cooperative and less cooperative subjects. Dental health is the area most commonly neglected. Bad breath, dropping food, or chewing on one side of the mouth are signs of dental pain that warrant a vet visit rather than a wait-and-see approach.Health signs to watch for in senior cats
Senior cats are good at masking discomfort — this is not stubbornness but instinct. In the wild, showing weakness is a liability, and domestic cats retain that tendency. By the time a cat appears visibly unwell, the issue is often further along than it would be if caught earlier. Changes worth acting on promptly:- Weight loss, even gradual — a few ounces a month adds up quickly and often signals something systemic
- Increased or decreased water intake
- Changes in litter box habits, including frequency, consistency, or any sign of straining
- Reduced appetite or a sudden preference change (a cat who loved dry food now refusing it may be in dental pain)
- Increased vocalization, particularly at night
- Disorientation, changes in sleep pattern, or appearing "lost" in familiar spaces
