Grooming behaviour in cats is both a welfare indicator and a welfare need - over-grooming signals stress while under-grooming signals pain or illness, making observation of grooming patterns valuable.
Grooming pattern changes are often the first observable sign of a welfare problem in cats. A previously well-groomed cat that stops grooming may be in pain. A cat that over-grooms may be anxious. Observant owners who monitor their cat's grooming behaviour can detect welfare concerns early, enabling prompt veterinary attention before problems become severe.
