Persistent mats need a plan that addresses both the existing knots and why they keep returning. Do not tug at tight matting or cut close to the skin with scissors. Ask a vet or experienced cat groomer for help with established mats, particularly if the skin looks sore or the cat reacts painfully. Once the coat is manageable, use brief regular checks suited to its texture and the cat's tolerance. Areas affected by friction may need attention even when the top of the coat looks smooth.
A change in mobility, weight or grooming behaviour can contribute, so new or worsening matting deserves veterinary discussion. Keep notes about where tangles appear and how quickly they form. That information helps a professional recommend a realistic routine instead of simply repeating a stressful dematting session whenever the problem becomes visible. Record the location of each recurring knot, such as behind a leg or under a collar, so the maintenance plan targets the areas actually causing difficulty.
