Cats are smart animals who are typically mindful of what they eat. But sometimes, seeds or pollen of a toxic plant get stuck in their fur or on their paws, and cats may ingest toxic substances while grooming themselves. To avoid this and keep your cat safe, all pet parents should take some time to learn the names of plants that are toxic to their health. Some of these plants are mentioned below. Peace lily (spathiphyllum) All its parts, including the leaves, roots, petals, and pollen, should be kept away from cats. If cats ingest peace lilies, they could get acute kidney failure. Other symptoms of poisoning would include vomiting, irritation of the mouth and GI tract, excessive drooling, and in rare cases, difficulty swallowing or breathing. Sago palm (cycas revoluta) Sago palm contains a toxic substance called cycasin, which, when consumed, may result in liver damage in cats. It could also cause vomiting, diarrhea, and black, tarry-looking stool. It could also lead to bruising, excessive thirst, lethargy, and in rare cases, death. Eucalyptus (myrtaceae) Eucalyptus can cause complications like drooling, vomiting, decreased appetite, and diarrhea in cats. The toxicity level of this plant is low, and the symptoms often disappear within 24 hours.
