Most pyrethrin poisoning happens when a well-meaning owner uses too much of a pyrethrin-based product or uses one that is too strong for a cat. Kittens, elderly cats and underweight cats are even more susceptible to pyrethrin toxicity. This is because their bodies can't process the chemical as well, and the lack of a protective layer of fat allows the chemical to soak right into muscles and tissues.
Pyrethrins are nature's way of lending gardeners a helping hand when it comes to controlling pests. A group of six chemicals, pyrethrins come from the flowers of the pyrethrum or Dalmatian daisy (Chrysanthemum cinerariaefolium), which is hardy in U.S. Department of Agriculture plant hardiness zone 10.Related substances are pyrethrum, which is a mixture of pyrethrins, and pyrethroids, man-made versions of pyrethrins.ried pyrethrum daisy petals provide pyrethrins, or the chemicals are extracted using solvents. The pyrethrum daisy grows in Ecuador, Kenya, Rwanda and Tanzania. After the newly opened flowers are harvested, they're dried and crushed into a powder or soaked in solvent to dissolve the pyrethrin-rich oil.
