FAQ

Is dahlia toxic to cats?

Yes. Dahlia (Dahlia species) is S2 Irritant for cats. The ASPCA lists "Mild gastrointestinal signs, mild dermatitis" and gives the toxic principles as "Unknown". The source does not identify a specific toxin or name individual gastrointestinal signs. Move the plant out of your cat's reach and contact your vet if signs persist or worsen.

What does the dahlia verdict cover?

The ASPCA's Dahlia entry names "Dahlia species" and gives "Many varieties" in its Additional Common Names field. This is a genus-level entry; it does not list named varieties one by one. This page follows that stated scope. A plant whose scientific name is outside Dahlia is outside this verdict. We do not grade plants that the checked sources do not cover. Check the scientific name on the tag.
