Many popular houseplants like Lilies, Sago Palms, and Pothos are toxic to cats. If your furry friend loves to nibble, stick to this list.
Why Are Some Plants Toxic?
Plants defend themselves with chemical warfare.
- Calcium Oxalates: Found in Monsteras, Philodendrons, and Dieffenbachia. These are microscopic needle-shaped crystals that cause immediate pain, drooling, and swelling if chewed.
- Saponins: Found in Aloe Vera and Snake Plants. Causes vomiting/diarrhea.
- True Poisons: Found in Lilies (highly toxic to kidneys) and Sago Palm (highly toxic to liver).
