What changes should I watch and log in my senior cat?
Cats hide illness well and often show no sign until a problem is advanced, so a written record of small senior changes is one of the most useful things you can bring to a vet. Age-related changes commonly begin between 7 and 10 years and are typical by 12.
Applies to: Cats roughly 7-10 years and older, or any cat your vet considers senior. This organizes what to observe; it does not identify the cause.
What to observe / record
- Reluctance or inability to jump onto favorite spots
- Creeping down from a height instead of jumping
- Difficulty getting into a high-sided litter box
- New mats, especially over the back and hindquarters
- Dull, greasy, or odd-smelling coat
- Log when the coat's condition starts to slip
- New or increased loud meowing at night
- Seeming lost or confused in familiar rooms
- More daytime sleeping with a restless night
- Rising or falling interest in food
- Noticeably more drinking or more/larger urine clumps
- A duller sense of smell can reduce an older cat's appetite
- Urinating or defecating outside the litter box
- Hiding more or avoiding favorite resting places
- Withdrawing from interaction it used to seek
Normal vs keep-watching
Normal: For a senior cat, normal is its own steady older-age pattern: predictable routine, consistent grooming, familiar sleep and social habits, and stable appetite, water, and litter use.
Keep watching: Because cats mask illness, treat any change, sudden or gradual, as worth logging with a date. Two or more changes appearing together deserve extra attention.
What changes this answer
- Advancing age raises the likelihood of cognitive and arthritis-related changes
- Some changes (thirst/urination) point toward specific systems and warrant prompter vet contact
- Environment matters: low-sided boxes and ground-level food and water reduce mobility strain
Common mistakes
- Dismissing new changes as 'just old age' instead of reporting them
- Missing increased thirst or urination because it is not being tracked
- Waiting for obvious signs when cats hide illness until it is advanced
