Many common flowers and plants are toxic to cats, with lilies being especially dangerous and potentially fatal. Other harmful varieties include amaryllis, daffodils, tulips, chrysanthemums, hyacinths, cyclamen, foxglove and crocus, causing symptoms from vomiting to severe organ damage. If you think your cat may have eaten a toxic plant, contact your daytime vet immediately, or if they’re closed, your nearest Vets Now clinic for urgent help
