Successful Management of Suspected Minoxidil Toxicosis in a Cat Following Accidental Dermal Exposure

A 4-year-old Norwegian Forest cat experienced anorexia, lethargy, and dyspnoea after accidental dermal exposure to minoxidil, a treatment for human alopecia. The cat exhibited hypothermia, tachypnoea, hypotension, and pulmonary issues. Despite initial supportive therapy, the condition worsened until minoxidil toxicosis was identified. Treatment with i.v. fluids and vasopressors, including dopamine and norepinephrine, normalized the cat's blood pressure and symptoms over 3 days. The cat fully recovered and was discharged 6 days post-exposure. This case was the first documented successful management of minoxidil toxicosis in a cat, providing insights and an optimized management plan for future cases.
