A seemingly innocent green pond can harbor a lethal threat that strikes within minutes: cyanobacteria toxins that vets have no cure for. Once a cat ingests these toxins, there’s no antidote—only emergency damage control. Discover what makes this garden hazard so dangerous and how to protect your cat.
