Sodium nitrate, a preservative that's used in some processed meats, such as bacon, jerky and luncheon meats, could increase your heart disease risk. It's thought that sodium nitrate may damage your blood vessels, making your arteries more likely to harden and narrow, leading to heart disease.
For third degree burns, keep the burned area covered with a wet cloth as much as possible to keep more chemical from washing into the wound. Once the chemical has been washed away as much as possible, cover the burn area with a fresh, wet cloth, wrap your cat in a dry towel and take him to your veterinarian.
If the burn is very recent, you can immerse the burn in cool running water for 10-15 minutes in order to lower the temperature and stop the burning process. Besides water, you don't put anything on a burn except a clean, dry dressing -- when performing first aid, you can also use clingfilm applied loosely in case the burn swells.
