Yesterday-Today-and-Tomorrow

Yes, Yesterday-Today-and-Tomorrow (Brunfelsia species) is considered potentially toxic to cats. All parts of the plant can cause serious harm if ingested, including neurological signs such as tremors and seizures.

Watch for hypersalivation and vomiting first, followed by tremors, twitching, agitation or anxious pacing, incoordination, and seizures. Diarrhea, lethargy, and coughing have also been reported. Seizures may persist or recur for several days in severe cases.

Call ASPCA Animal Poison Control (888-426-4435) or Pet Poison Helpline (855-764-7661) immediately and head to an emergency vet — any suspected ingestion warrants an urgent visit. Do not induce vomiting at home, especially if your cat is already tremoring or seizing. Bring a piece of the plant or a clear photo so the veterinary team can confirm the plant.

Onset is typically within 2 hours but can take several hours; exact timing in cats is not well documented, as most reported cases involve dogs. Because seizures can persist for days in severe cases, hospital monitoring is often required even after initial treatment.
