Porphyrias is a term for a group of rare metabolic disorders that affect a cat’s ability to produce heme. Heme is an essential part of hemoglobin—a protein found in red blood cells that brings oxygen from a cat’s lungs to other parts of their body. Different types of porphyrias can occur in cats, as well as in humans and other animals. In this blog, we’ll discuss acute intermittent porphyria (AIP) in cats, its symptoms, and how it is diagnosed and treated by veterinarians.
