text: … Stray cats have been listed as “vermin” since the early 1900’s. This is why it is even legal to use any and all vermin-poisons on them. For an even more species-specific vermin poison check into the toxicity of “Lilium” species of flowers too. Be certain the plant contains the word “Lilium” in the scientific-name (other plants with the word “Lily” in the common-name may be toxic to other species besides cats). Common N. American “Day Lilies” (Hemerocallis graminea) also work, they are the one exception to the rule that the name “Lilium” needs to be in the scientific name. Lilium species of flowers are 100% fatal to cats ONLY, even a bit of pollen on their fur that they lick-off will do. If they even drink a bit of water in which a bunch of Lilium flowers have been kept – that too is fatal, but totally harmless to all other species of animals (including dogs).
