Is geranium toxic to cats?
Geranium (pelargonium spp.) is toxic to cats. The toxic principles are linalool and geraniol. Geraniol is an acyclic monoterpene alcohol found in several plants including geraniums, thyme, lemon balm, coriander and palmarosa. Its rose-like fragrance makes it a common ingredient in beauty products and as well as insecticides. Geraniol can cause allergic dermatitis in people and animals.
Linalool is a terpene alcohol that naturally occurs in lavender, bergamot, thyme, coriander, basil and neroli. Exposure is associated with central nervous system effects including ataxia (wobbly gait), depression, vomiting and diarrhea.
