Rogaine (Minoxidil) Is Killing Cats in 2026 — The Pillowcase Nobody Warned You About
ASPCA (Feb 26, 2026): even very small minoxidil exposures can cause life-threatening cardiovascular collapse in cats — no antidote exists. Reports to ASPCA Poison Control increased 965% from 2013 to 2024 (JAAD 2025 study). 14.7% cat mortality in a 68-case clinical series (vs. 0% dog mortality). Cats are exposed not by direct application but by lying on treated pillowcases, licking their owner's scalp after application, or grooming their own fur after contact. This guide covers the full symptom timeline (45-min onset), emergency treatment protocol, every hidden exposure route, and the complete safe-use checklist for households that use Rogaine and have cats.
