Frida was saved
Our 10 month old Frida was in bad shape. Feverish, barely eating and drinking, loosing weight. The vet confirmed she had serious symptoms of FIP. We were loosing her. We chose CURE FIP USA because it was easy to select pills according to Frida’s weight. After a few days, the fever was gone and the appetite came back. After three weeks, she had gained weight. The 84 days treatment is complete and she is full of energy, running, climbing trees. A new blood test confirmed the FIP markers are gone.Read more
