As a dedicated veterinarian, I understand the concerns pet owners face when their beloved feline companions exhibit signs of digestive distress. Deoxynivalenol (DON), also known as vomitoxin, is a mycotoxin produced by the Fusarium fungus that can contaminate grains used in cat food, leading to mycotoxicosis. In this comprehensive guide, we'll explore the causes, symptoms, diagnosis, treatment options, and prevention strategies for DON mycotoxicosis in cats, ensuring you're well-equipped to support your cat's health in 2025.
