A natural remedy for constipation in cats is olive oil. Add one half to 2 tsps. of olive oil to your cat's food on a daily basis for no more than one week. Regular ingestion of olive oil could cause a vitamin A deficiency. As a constipation preventative, cats being fed only a manufactured dry food diet could have 1 tbsp. of olive oil added to their food a few times a week. Olive oil helps intestinal muscle contractions, stimulates bile flow and softens feces.
