Long-haired cats require regular grooming to prevent matting and tangles in their fur. It is recommended to brush their coat at least a few times a week to keep it healthy and free from knots. Using a metal comb or a slicker brush can help remove loose fur and prevent hairballs. Additionally, long-haired cats may benefit from occasional baths to keep their fur clean and reduce shedding. Regular grooming not only helps maintain the cat's coat but also promotes bonding between the cat and its owner.
