Onset and recovery times for feather geranium ingestion in cats are not well documented in the cited sources.
When to call the vet
Call your vet or ASPCA Poison Control (888-426-4435) if your cat eats more than a small mouthful, vomits more than once or twice, refuses food for more than a few hours, or seems unusually withdrawn.
What this means for your cat
Cats: feather geranium is listed by the ASPCA as toxic to cats. The active culprits are sesquiterpene lactones — the same family of compounds that make many ragweed and aster relatives unpleasant for cats — and ingestion is more likely to cause GI upset than acute systemic illness.
Sources: ASPCA.
