What to do
Usually resolves with monitoring; cats are noted to be somewhat more sensitive to geranium oil than dogs.
Toxic component and mechanism
The toxic component in Geranium is geraniol and linalool (essential oils).
What makes this plant different
Geranium essential oil is a common ingredient in some natural flea and tick repellent products — a reminder that 'natural' doesn't necessarily mean risk-free, since the same oil causes mild toxicity if the plant itself is eaten.
