Everything about grooming an older cat gets gentler: softer tools, a lighter hand, shorter sessions, a warm room to work in. Age thins the skin as surely as it thins the coat, and skin with less padding underneath marks, tears and bruises at pressures a younger cat would never notice. Treat every session as handling something fragile that happens to purr.
Let her settle on something padded, with her weight supported, and groom in the direction the coat lies rather than back-combing for effect. A mitt, or a brush with soft bristles, usually suits sensitive skin better than slickers or combs with fine metal teeth, which catch and drag where the skin has lost its padding. Work in passes of a minute or two, with strokes she leans into, and stop on the day she shifts away repeatedly — a half-groomed cat who trusts the routine beats a fully groomed one who hides from the brush tomorrow.
The Areas She Can No Longer Reach
Arthritis and stiffness quietly retire a senior cat's own grooming long before she looks unkempt: the back, the hindquarters and the base of the tail are the stretches her spine no longer lets her twist to. Concentrate your gentle passes there, where loose fur and dandruff accumulate, and part the thinning coat as you go to read the skin itself — scabs, lumps, sore patches, flaky areas and any spot that bruises at a touch. Check under the chin and along the jaw too, where older cats can develop soreness they hide by eating less enthusiastically.
Changes That Belong to the Vet, Not the Brush
Skin that bruises, tears or develops sores easily deserves a vet check, not just gentler brushing: thinning and fragility can be part of ageing, but they also travel with conditions a vet should rule out. Take photographs of new lumps and note the date you found each one, so growth between visits is measured rather than guessed. Report coat changes alongside appetite, weight, mobility and thirst, because in a senior cat those details arrive as one picture, and the grooming session is often where the first pieces of it surface.
Senior vet checks at least twice a year give those findings somewhere to go; bring the dated notes rather than relying on remembering which lump was new.
Building the Record as You Groom
Because each session doubles as a skin inspection, its findings are worth keeping in one place rather than in memory: dates of sessions, what the skin looked like, which areas are thinning fastest, and how she tolerated the handling. File that running record in your Pet Passport on KinsLe, and the packet that travels with her — to the vet, to a boarder, or into a sitter's hands — already explains her fragile skin and the gentle handling it needs.
