Water lilies are not toxic to cats, and owners can keep them at home. However, do not keep lilies, azaleas, oleanders, daffodils, or other similar plants at home, as these plants contain certain toxic substances that can seriously harm cats and, in severe cases, even lead to death.

If the owner insists on keeping this type of substance, they can place it in places such as the balcony or kitchen, ensuring that the cat does not accidentally ingest it and become poisoned.
