Even though your cat grooms herself constantly, brushing is still important because it helps remove loose fur, reducing hairballs and the amount of fur on your belongings. Brushing also distributes natural skin oils throughout her coat, keeping her fur healthy and shiny. For older cats or those with long hair, brushing aids in grooming areas, they can't easily reach or manage themselves, preventing mats and tangles. Additionally, regular brushing sessions provide an opportunity to bond with your cat and check for any signs of skin issues or changes in her health.
