CRITICAL DISCLAIMER: If you suspect your pet has ingested ANY of the plants below, contact your veterinarian IMMEDIATELY! Time is of the essence.
1. Lilies (Lilium & Hemerocallis species) - The #1 Threat to Cats
· Toxic to: Cats and Dogs, EXTREMELY TOXIC AND OFTEN FATAL TO CATS! (May cause only mild stomach upset in dogs, but still avoid).
· Common Types: Easter Lily, Tiger Lily, Asiatic Lily, Daylily.
· Toxic Parts: EVERY PART! Petals, leaves, stems, pollen, and even the water in the vase.
· Mechanism & Symptoms:
· Mechanism: The toxin causes acute tubular necrosis in the kidneys, leading to rapid kidney failure.
· Symptoms: Vomiting, lethargy, and loss of appetite can appear within 2-4 hours of ingestion. Ingesting just two leaves or a small amount of pollen can cause fatal kidney failure within 36-72 hours without immediate treatment.
· "PLANTIMAL" Safe Tip: If you have a cat, do not allow any lilies into your home. Thoroughly inspect all bouquets and remove them immediately.
2. Sago Palm (Cycas revoluta) - A Deadly Threat to Dogs
· Toxic to: Cats and Dogs, EXTREMELY TOXIC AND OFTEN FATAL TO DOGS!
· Toxic Parts: All parts are highly toxic, but the seeds ("nuts") are the most potent.
· Mechanism & Symptoms:
· Mechanism: The primary toxin, cycasin, causes severe and often irreversible liver damage.
· Symptoms: Violent vomiting, diarrhea (may be bloody), lethargy, abdominal pain, jaundice (yellow gums), seizures, and liver failure. The mortality rate is very high. Even with aggressive treatment, surviving dogs may have permanent liver damage.
· "PLANTIMAL" Safe Tip: These are often planted in parks and landscapes. Be vigilant on walks. Never keep one in your home.
3. Pothos/Devil's Ivy & Dieffenbachia - The Oral Irritants
· Toxic to: Cats and Dogs
· Common Types: Golden Pothos, Dieffenbachia (Dumb Cane), Philodendron, Peace Lily.
· Toxic Parts: Entire plant (leaves and stems).
· Mechanism & Symptoms:
· Mechanism: Contain insoluble calcium oxalate crystals. These microscopic, needle-shaped crystals penetrate and irritate the soft tissues of the mouth, throat, and GI tract.
· Symptoms: Immediate and intense oral pain, burning, and inflammation, excessive drooling, vomiting, difficulty swallowing, and swelling of the mouth. While rarely fatal, the experience is extremely painful and swelling can block airways.
· "PLANTIMAL" Safe Tip: These are among the most common houseplants. Always keep them in hanging baskets or on high shelves, far out of reach.
4. Tulip & Daffodil - The Deceptive Bulbs
· Toxic to: Cats and Dogs
· Toxic Parts: The bulbs are the most toxic part. Leaves and flowers are also harmful.

· "PLANTIMAL" Safe Tip: Be extra cautious with gifted bouquets or bulb kits during holidays. Ensure they are placed where pets cannot access them.
5. Oleander - The Outdoor King of Toxins
