How can I help my 19-year-old cat with matted fur?

To help your 19-year-old cat with matted fur, gently brush the fur daily to prevent mats from forming. Use a comb or brush specifically designed for cats to avoid causing discomfort. If the mats are severe, consider taking your cat to a professional groomer or veterinarian for assistance. Regular grooming and proper nutrition can also help prevent future matting.
