My cat is taking inhaled steroids twice a day for asthma. When I reduced the dose, he would immediately cough. But after giving him nutritional supplements for a month and reducing the steroid dose, he hasn't coughed yet. Every cough was so frustrating, but now he's completely recovered, so I'm so grateful. He's a very picky eater, so I mix it in his favorite chew and he enjoys it. I plan to continue feeding him this.
