Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.

What this means for your cat

Cats that nibble on dahlia foliage or flowers usually develop only mild stomach upset, but the ASPCA does list dahlias as toxic to cats. The toxic principle isn't known, and reactions are typically short-lived but uncomfortable.

What to watch for

Most cases are mild. Watch for vomiting, diarrhea, drooling, and a brief drop in appetite after a chew. Cats that contact the sap may also show localized skin irritation or a transient rash where the plant touched their skin.

Time window

ASPCA does not document onset or duration. Veterinary references generally describe mild gastrointestinal signs that resolve within roughly 24 hours with supportive care.

When to call the vet

Call your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) if vomiting continues past a few episodes, your cat refuses food for more than a few hours, or skin irritation becomes raw, swollen, or hives appear.

Sources: ASPCA (no first-aid guidance).

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.
