The solution for an oily tail in cats is cleaning. An oily tail makes a cat's body sticky and gives off an odor. Cleaning an oily tail requires warm water and a mild detergent; it's best to avoid harsh chemical cleaners. Use a soft-bristled brush or cotton pad soaked in detergent to gently wipe the tail and surrounding area. 
In addition, solutions for oily tails in cats include changing their diet. Cats that prefer high-fat and high-calorie foods tend to produce excessive sebum, leading to an oily tail. Therefore, we can control our cat's diet and avoid feeding them too many high-fat foods.
In daily life, we can reduce oily tail problems in cats through regular brushing. Brushing your cat regularly every day promotes blood circulation, strengthens their immunity, and removes excess oil from their skin. Furthermore, brushing strengthens the bond between cat and owner, increasing interaction. In conclusion, cleaning, changing dietary habits, and regular brushing are effective ways to address oily tail problems in cats.
