If a plant is toxic to pets, it contains compounds that can cause adverse reactions when ingested, chewed, or sometimes even touched. Toxicity levels vary depending on the plant species and the size or health of the animal.
Common symptoms in cats, dogs, and other small pets include vomiting, diarrhoea, drooling, irritation of the mouth or throat, lethargy, and in severe cases, difficulty breathing or organ damage.
Some plants contain insoluble calcium oxalates, alkaloids, or saponins that irritate the digestive system, while others may have compounds affecting the heart or nervous system.
Being aware of which plants are toxic allows you to make safer choices for your indoor garden and take preventative measures, such as placing plants out of reach, using hanging baskets, or choosing non-toxic alternatives. If a pet ingests a toxic plant, contact a vet immediately.
