Bella, our 3.5 kg Ragdoll, was critically ill with FIP. Our vet recommended EIDD-1931 Molnupiravir. Within weeks, Bella regained strength and began eating normally. The lower toxicity minimized side effects, making her more comfortable. Bella is now much better, thanks to this effective medication.
