Can slippery elm be used on cats?

Fish oil (especially Cod Liver Oil) is good for your cat, but phone the vets and ask how much you can give them. You can get those little syringes to measure it by and mix it in your pets food. This is also good for dogs. I wouldn't get too fancy with your pet because it can upset their digestive tract. In responding to the slippery elm aspect of the question, it is considered safe to give to cats. I'm not sure about the glycerin, but I don't know that it's necessary. Slippery elm has wonderful anti-inflammatory qualities, and is very soothing to the intestinal/digestive tract. Author Anitra Frazier gives the following recipe for Slippery Elm Bark syrup in her book, The New Natural Cat: Into a small saucepan place 1/2 cup cold water and 1 teaspoon powdered slippery elm bark. Whip with a fork. Bring to simmer over low flame, stirring constantly. Simmer 1 or 2 minutes or until slightly thickened. Cool and refrigerate. Keeps 7 or 8 days. Give a teaspoon of syrup (5 cc) for an average-size cat (again, about 10 pounds) 5 minutes before a meal to minimize diarrhea, or to soothe and heal mouth ulcers.
