Dianthus

Yes, dianthus (Dianthus spp.) is considered potentially toxic to cats. The plant contains compounds that cause gastrointestinal irritation, though symptoms are typically mild.

Expect mild vomiting, possible diarrhea, and mild skin irritation if your cat rubbed against the foliage. Loss of appetite for a meal is common; severe systemic illness is not described for this plant.

Monitor your cat closely for vomiting and diarrhea, which typically appear within a few hours and resolve in 12 to 24 hours. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if vomiting continues past 24 hours, your cat refuses to drink, becomes lethargic, or ate a large quantity of the plant.

Exact onset and duration are not specified by ASPCA, but mild GI signs from low-grade plant irritants like those in dianthus typically appear within a few hours and resolve within 12 to 24 hours with supportive care. Call your vet if symptoms persist beyond 24 hours or your cat stops drinking.

Yes, dianthus is considered potentially toxic to dogs. The plant contains compounds that can cause gastrointestinal irritation, though the overall poison severity is characterized as low — most ingestions result in mild, temporary digestive upset rather than a serious emergency.

The most common signs are vomiting, diarrhea, and soft stool. If your dog mouthed or chewed the foliage, you may also notice skin irritation — redness or swelling on the muzzle or paws. Symptoms typically appear within a few hours of ingestion and tend to resolve within a day with supportive care.

Monitor your dog closely for vomiting, diarrhea, or skin redness. For mild symptoms, supportive care (rest, water) is usually sufficient. Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 if vomiting persists more than 24 hours, your dog seems lethargic, or you notice persistent skin swelling or refusal to eat.

The foliage is the main concern — dogs that mouth or chew the leaves can develop both gastrointestinal upset and contact dermatitis on the muzzle or paws. The available data does not single out seeds, stems, or flowers as significantly more dangerous than the rest of the plant.
