Is Geranium safe for cats and dogs?

Severity: Mild
UC's Statewide Integrated Pest Management Program writes its home-and-landscape guidance for "urban Californians" specifically, noting its advice is tailored to "pests and conditions in California." Its geranium (Pelargonium) page describes a woody perennial that attracts hummingbirds, tolerates full sun but appreciates some shade in extreme heat, and needs only "moderate to regular amounts of water" in well-drained soil - modest requirements a UC Cooperative Extension Master Gardener in Solano County backs up from direct experience, writing that geraniums "continuously bloom all year in places with mild winters," survived in a "brick bed that hardly got any water," and are simply "tough as nails." That combination of year-round bloom and low water needs is a large part of why geranium shows up in more California porches, window boxes, and traffic-median planters than almost any other flowering plant.
ASPCA lists geranium as toxic to dogs and cats, with geraniol and linalool as the toxic principles and documented signs of vomiting, loss of appetite, depression, and dermatitis. The dermatitis risk tracks with how often people handle this particular plant - deadheading spent blooms is standard geranium care - so a pet with skin irritation after contact, or one that has chewed on the leaves and is vomiting or off its food, should be checked by a veterinarian if the signs persist.
